Penalty ( gridiron football ) - wikipedia Penalty ( gridiron football ) NFL back judge Lee Dyer retrieves a penalty flag on the field during a game on November 16, 2008 between the San Francisco 49ers and St. Louis Rams. In American football and Canadian football, a penalty is a sanction called against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow ( American football ) or orange ( Canadian football ) colored `` penalty flag '' onto the field toward or at the spot of a foul. Many penalties result in moving the football toward the offending team 's end zone, usually either 5, 10, or 15 yards, depending on the penalty. Most penalties against the defensive team also result in giving the offense an automatic first down, while a few penalties against the offensive team cause them to automatically lose a down. In some cases, depending on the spot of the foul, the ball is moved half the distance to the goal line rather than the usual number of yards, or the defense scores an automatic safety. Contents 1 Rationale 2 Signaling and announcing penalties 3 General types of penalty enforcement 4 Intentional fouls 5 The ten - second runoff rule 6 List of penalties 7 See also 8 References Rationale Because football is a high - contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contact, and actions of players on each team. It is very difficult to always avoid violating these rules without giving up too much of an advantage. Thus, an elaborate system of fouls and penalties has been developed to `` let the punishment fit the crime '' and maintain a balance between following the rules and keeping a good flow of the game. Players and coaches are constantly looking for ways to find an advantage that stretches the limitations imposed by the rules. For example, in 2016 the Baltimore Ravens had all of their offensive linemen commit holding penalties in order to allow the punter to keep possession of the ball so time would expire for a win, since the game can end on offensive penalties. However, the NFL changed the rules after this to prevent teams from manipulating the game clock. The frequency and severity of fouls can make a large difference in the outcome of a game as well, so coaches are constantly looking for ways to minimize the number and severity of infractions committed by their players. It is a common misconception that the term `` penalty '' is used to refer both to an infraction and the penal consequence of that infraction. A foul is a rule infraction ( e.g. offensive holding ) for which a penalty ( e.g. move back 10 yards ) is assessed. Signaling and announcing penalties Officials initially signal fouls by tossing a bright yellow colored flag onto the field toward or at the spot of the foul. Because of this, broadcasters and fans often use the terms `` flag '' or `` flag on the play '' to refer to fouls during the game. During a play, multiple officials may flag the same play, and multiple flags may be thrown for separate fouls on the same play. If applicable, the same official can signal additional fouls on a given play by throwing a beanbag or their hat. When officials throw a flag during a down, play does not stop until the ball becomes dead under normal conditions, as if there were no fouls. Once the ball is dead, or immediately when a foul is called after a play is over or prior to a snap ( since the ball is dead anyway ), the referee, the official ( s ) who threw the flag ( s ) and other officials with a view of the play confer to come to a consensus on whether an infraction was actually committed, what it was, and who committed it. The final determination and assessment of the penalty is the sole responsibility of the referee. The referee then makes initial visual body signals to the press box indicating what fouls were committed and the team that committed them, the latter shown by extending the arm toward that team 's end zone. The referee then confers with the offended team 's on - field captain to find out whether the offended team would rather decline the penalty and take the result of the play. In certain situations, the result of the play may be more advantageous to the offended team, especially, for example, if time is running out in the half and a 7 - yard gain is a better option than a 5 - yard penalty. However, there are certain scenarios where the referee may not have to confer with the team captain because the enforcement can not be declined ( such as a false start foul or other penalties called prior to the snap ) or when the choice is fairly obvious ( such as when the defense commits a foul during a play in which the offense scores a touchdown ). After any final conference, the referee then makes full visual signals describing the foul in detail, consisting of : the foul that was committed, the team that committed it, whether or not the opposing team chooses to decline it, the resulting down or possession, and any other penalties such as disqualification ( ejection ) of a player from the game or a ten - second runoff from the game clock. In college football, the NFL and other professional leagues, and in some high school games, the referee also announces the fouls and their penalties over a wireless microphone to the members of the teams, the crowds in the stands, and viewers / listeners of the televised / radio broadcast of the game. In college and professional football, and high school in some states, the referee will also give out the numbers of the players who committed the fouls. During these announcements over the microphone, the referee usually does not use names of the respective teams or their cities ( however, in the Canadian Football League, they are announced by their respective city or province ), but rather will use the generic terms `` offense '', `` defense '', `` kicking team '', `` receiving team '', etc. Some officials, especially in high school and lower levels, will refer to teams by their jersey color ( e.g. `` white '', `` red '', `` blue '', etc. ). General types of penalty enforcement The following are general types of penalty enforcement. Specific rules will vary depending on the league, conference, and / or level of football. Most penalties result in replaying the down and moving the ball toward the offending team 's end zone. The distance is usually either 5, 10, or 15 yards depending on the penalty. However, such penalties, when enforced, are capped at half the distance to the offending team 's goal line. Depending on the foul, the spot where the penalty is enforced may be at the spot of the foul ; the previous spot ( the line of scrimmage where the down began ) ; the spot of the snap, fumble or backwards pass ; or the succeeding spot ( the line of scrimmage of the next down ). Some defensive penalties give the offense an automatic first down. Conversely, some offensive penalties result in loss of a down ( loss of the right to repeat the down ). If a penalty gives the offensive team enough yardage to gain a first down, they get a first down, as usual. Rules are asymmetrical in regard to whether a team can score directly as a result of a penalty. The offensive team can not do so ; if a foul that is penalized from the spot of the foul is called on the defense in its own end zone, the ball is placed on either the one - yard line or the two - yard line, and the offense must try to score from there. However, penalties called on the offense in its own end zone can result in the defense scoring a two - point safety. If the defense commits a foul during the last play of any quarter, the offense usually has the option to accept the penalty and replay the down even with the clock showing 00 : 00 ( i.e., an untimed play ). Conversely, in most cases where the offense commits a foul during the last play in the half, the play in which the foul is committed is usually nullified and the half ends. In the US, when multiple fouls occur, when both teams commit a foul during a play, regardless of severity, the fouls are usually offset and the down is replayed. However, the fouls must be committed in the same time frame. For instance, two fouls during the active play can offset, but a foul during the play and a personal foul after the whistle may not. Two personal fouls after the play can offset, although this is not often called. In the NFL, a major ( 15 - yard ) penalty by one team may not offset a minor ( 5 - yard ) penalty by the other team. In the CFL, the penalty yardage is generally netted : a 15 - yard penalty by one team and a 10 - yard penalty by the other will result in 5 net yards of penalty enforcement. Intentional fouls In certain situations, a team ( specifically in the NFL ) may intentionally commit a foul in order to receive a penalty that they see as advantageous : A delay of game penalty may be sought intentionally in order to back up the line of scrimmage prior to a punt to allow for a larger punting field. Defensive pass interference may be committed in or near the end zone toward the end of a game in order to prevent a touchdown. This would place the ball at or near the goal line with a first down, and give the defense of a team that is slightly ahead a chance to prevent a touchdown that would put the opponent ahead. Some leagues have considered instituting palpably unfair act calls in these situations and calling touchdowns to prevent this from occurring. Since a penalty will stop the clock, a team may commit a foul in order to stop the clock when no timeouts are available. Some leagues have instituted a 10 - second runoff in order to negate the ability to do this. ( See below. ) The ten - second runoff rule In the NFL and NCAA, a 10 - second runoff is assessed if any of the following acts are committed by the offense in the last minute of either half ( as of 2017, after the two - minute warning in the NFL ) : A foul by either team that prevents the ball from being snapped Intentional grounding Illegal forward pass beyond the line of scrimmage Throwing a backwards pass out of bounds Any other intentional act that causes the clock to stop The 10 - second penalty does not apply if : The clock is stopped when the ball is set for play and will not start until the ball is snapped. If the team on offense has timeouts and elects to use one in lieu of the runoff. If the defense declines the runoff ( which prevents the offense from committing fouls to intentionally run out the clock ). Note that the team on defense may elect to decline the runoff while accepting the yardage penalty, but may not do the reverse. Moreover, the game clock will run once the ball is placed. If such a runoff occurs with 10 seconds or less remaining, the half automatically ends. Since the enforcement of the 10 - second runoff, eight regular season NFL games ended automatically due to this rule : 2005 Arizona - St. Louis, 2009 Cincinnati - Green Bay, 2011 Chicago - Oakland, 2012 Washington - Philadelphia, 2012 New England - Arizona ( which cost New England the chance to attempt a field goal at the end of the half in a game they eventually lost by two points ), 2014 St. Louis - Tampa Bay ( which cost Tampa Bay a chance to attempt a game - winning field goal ), 2015 New England - New York Jets ( which cost the Jets an attempt to throw a Hail Mary and force the game to overtime ) and 2017 Atlanta - Detroit ( which cost the Lions a chance to win the game ). A pre-season game in 2006 between Houston and Kansas City had the first half end automatically due to an intentional grounding foul with less than 10 seconds left. A 2013 divisional playoff game between the New Orleans Saints and the Seattle Seahawks also ended on a 10 - second runoff after Saints wide receiver Marques Colston threw an illegal forward pass. Starting in 2011, the NCAA adopted a similar 10 - second penalty rule for college football. Like the NFL rule, it applies in the last minute of each half, but the NCAA rule differs in that it applies to fouls by either side that cause a clock stoppage. Like the NFL rule, the team that benefits from the penalty may elect to take both the yardage and the runoff, the yardage alone, or neither ( but not the runoff in lieu of yards ). The penalized team may elect to take a charged timeout in order to avoid the runoff. The new NCAA rule was passed in response to the end of the 4th quarter in the 2010 Music City Bowl. In that game, the North Carolina Tar Heels were down 20 - 17 at the end of the 4th quarter and because they had no timeouts, they spiked the ball to stop the clock with 1 second left while too many men were on the field due to confusion about whether the field goal unit needed to come on the field. Because college football did not yet have the 10 - second runoff, UNC was penalized 5 yards but was still able to kick the field goal to send the game to overtime, and would wind up beating Tennessee 30 - 27 in double overtime. Ironically, the new rule would not have saved Tennessee, because the Tar Heels ' foul came after the snap, which would not have triggered the runoff. List of penalties In the NFL, most defensive penalties result in an automatic first down. The exceptions are offside, encroachment, neutral zone infraction, delay of game, illegal substitution, calling excess timeouts, running into a kicker, and having more than 11 men on the field. In these cases, the appropriate yardage penalty is assessed. If the yardage penalty results in a first down, then a new set of downs is awarded ; otherwise, there is a repeat of down. Foul Description Signal Penalty Yardage NFL NCAA HS CFL Blocking below the waist An illegal block, from any direction, below the waist by any defensive player or by an offensive player under certain situations, by any player after change of possession, by any player in high school with certain exceptions. Sometimes incorrectly referred to as a `` chop block ''.

Called an `` illegal block '' in the CFL. One arm extended horizontally in front of the body, palm facing outward. The other hand grasps the first hand 's wrist and pushes outward 10 yards 10 yards 10 yards 10 yards Chop block ( offense ) An offensive player tries to cut block a defensive player that is already being blocked by another offensive player. The second block may need to be below the thigh or knee, depending on the code. ( US ) Arms extended alongside the body, palms facing outward, then moving in to the upper thigh in a chopping motion. ( CFL ) Both hands held out flat, facing each other, in front of the referee, moving down together diagonally roughly from one shoulder to the opposite hip. 15 yards ( if it is in the end zone the play will be ruled a safety ) ; automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). 15 yards ; automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). 15 yards 15 yards ; automatic first down if committed by defense Clipping ( offense, defense, or special teams ) A blocker contacting a non-ballcarrying opponent from behind and at or below the waist Chopping the back of one thigh with the hand. 15 yards ; automatic first down if committed by defense 15 yards ; automatic first down if committed by defense 15 yards 15 yards ; automatic first down if committed by defense Delay of game ( offense, defense, or special teams ) Any action which delays the next play. In the US, on offense, this includes failing to snap the ball before the play clock reaches zero. ( In the CFL, that action is a time count violation. ) It may also include spiking the ball. On defense, it occurs when a player hinders the offense in hurrying to make the next snap. This happens most often in the last two minutes of a half when the offense is trying to go down the field in a hurry. The defense can also be flagged for a delay of game if a player spikes the ball after the end of a play. On special teams, it happens when the return team runs after signaling for a fair catch, or the defense does not unpile in a timely manner after the play ends. ( US ) Upper arms extended out from the body, forearms bent toward the opposite arm, such that the arms lie on top of one another or that each arm touches the opposite shoulder.

If the equipment is deemed hazardous, 15 yards and disqualification. Face mask ( offense, defense, or special teams ) Grasping the face mask of another player while attempting to block or tackle him. In the NFL, the grasping and pulling / twisting must be intentional to be penalized. Under NCAA rules, it is a foul to grasp and twist the face mask. Under high school rules, any grasping of the face mask, any helmet opening, or the chin strap is a foul, though grasping and twisting carries a more severe penalty than `` incidental '' grasping without any twisting. One arm in front of the body, forearm extended vertically. The hand is closed into a fist in front of the face and pulled downward 15 yards ; automatic first down if committed by defense 15 yards ; automatic first down if committed by defense 15 yards for grasping and twisting, 5 yards for incidental grasping 15 yards ; automatic first down if committed by defense False start ( offense ) An offensive player illegally moves after lining up for -- but prior to -- the snap.

Can also result in a fine and / or suspension. see Targeting, below see Targeting, below 15 yards see Unnecessary roughness, below Holding ( offense or defense ) Illegally grasping or pulling an opponent other than the ball carrier while attempting to ward off a block or cover a receiver. One of the most commonly called penalties. If a penalty for holding that occurred in the offense 's end zone is accepted, a safety results. Raising one arm in front of the body ( forearm is roughly vertical with elbow at bottom ) and grabbing its wrist with the opposite hand Offense, 10 yards. If it is called in the end zone by the offense, it 's an automatic safety ; defense, 5 yards and automatic first down. 10 yards 10 yards 10 yards Horse - collar tackle Illegally tackling another player by grabbing the inside of the ball carrier 's shoulder pads or jersey from behind and yanking the player down. ( US ) Raising one arm to the side of the body with the elbow bent, so that the closed fist is located near the neck. The fist is then pulled away, horizontally, from the neck. ( CFL ) Same as unnecessary roughness ; it is a subset of that penalty 15 yards, automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). 15 yards, automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). 15 yards 15 yards Illegal batting ( offense ) Any intentional batting of a loose ball or ball in player possession.

The illegal contact is called only if the quarterback is still in pocket and the ball is still in his hands. This rule was adopted in 1978, and its enactment is regarded as contributing to the increase in passing efficiency the NFL has witnessed since that time. One arm in front of the body with palm out and fingers up, moved in a pushing motion out 5 yards and an automatic first down Does not exist Does not exist 10 yards Illegal formation Fewer than 7 players line up on the line of scrimmage ( NFL / High School / CFL ) ; more than four players in the backfield ( NCAA only ) ; eligible receivers fail to line up as the leftmost and rightmost players on the line ( NFL / CFL ) ; or when five properly numbered ineligible players fail to line up on the line.

One arm in front of chest, palm open and down, with the elbow out to the side, moved away from chest. 5 yards 5 yards 5 yards Illegal participation Twelve or more players participate during the play, because the extra players either are not detected before the snap or enter during the play. Once the down begins, no further players may enter the field and participate, even if there are fewer than 11 players.

( NCAA / High School ) arm along the side of the body with the palm of the hand touching the opposite shoulder ; ( NFL ) two hands, palms down, touching the top of the head, with an elbow out to each side 5 yards 5 yards 5 yards Illegal touching of a forward pass ( offense ) A forward pass first touches an ineligible receiver ( an offensive lineman ). If the ball is touched by the defenders first, any player may touch it. One hand held up to shoulder, fingertips touching the shoulder ; ( NFL ) two hands held up to shoulders, fingertips touching the shoulders. 5 yards and a loss of down 5 yards ( if touched by an originally ineligible receiver ) / 5 yards and loss of down ( if touched by an originally eligible receiver who voluntarily went out of bounds ) 5 yards and a loss of down Illegal touching of a free kick ( special teams ) The ball, after the free kick, first touches a member of the kicking team prior to travelling 10 yards. This is most often seen on an onside kick where a member of the kicking team prematurely comes in contact with the ball in an attempt to recover it. Like illegal touching of a forward pass, if a defender ( member of the receiving team ) first touches the ball, any player may touch it. Note : in NFHS it is called ' first touching ', not ' illegal touching '. It is also illegal touching for a kicking team player to touch a free kick after going out of bounds, unless the kick is touched by the receiving team. One hand held up to shoulder, fingertips touching the shoulder ; ( NFL ) two hands held up to shoulders, fingertips touching the shoulders. 5 yards, unless the illegal touching occurs inside the receiving team 's 5 yard line. In that case, it is ruled a touchback. Five yards from the previous spot, or five yards from the spot where the subsequent dead ball belongs to the receiving team, or from the spot where the ball is placed after a touchback. Not a foul. Receiving team may take possession at the spot of touching unless it commits a foul. Illegal touching of a scrimmage kick ( special teams ) The ball, during the scrimmage kick, is touched by a kicking team player, unless the kick is touched by the receiving team or another member of the kicking team. One hand held up to shoulder, fingertips touching the shoulder ( NFL ) ; two hands held up to shoulders, fingertips touching the shoulders ( NCAA ). Not a foul. Receiving team has the option of taking possession at the spot of illegal touching unless it commits a foul. Not a foul ( called `` first touching '' in the NFHS rulebook ). Receiving team may take possession at the spot of first touching unless it commits a foul. Illegal use of hands Illegal use of the hands against a player on offense while attempting to ward off a block, cover a receiver, or tackle a ball carrier. There are several restrictions on how a defender may initiate contact. One forearm vertically held in front of the body with an open fist facing away from the referee 's chest ( closed fist for a HS referee ) ; the other hand grasping the first arm 's wrist 10 yards if committed by offense ; 5 yards and automatic first down if committed by defense 10 yards, automatic first if committed by defense against an eligible receiver 10 yards Ineligible receiver downfield ( offense ) An ineligible receiver is past the line of scrimmage prior to a forward pass. Ineligible receivers must wait until the pass is thrown beyond the line of scrimmage ( or touched ) before moving past the line of scrimmage. This exception has been added to accommodate the screen pass, where a receiver ( most often a back, but sometimes a tight end or wide receiver ) catches a ball behind the line of scrimmage behind a `` screen '' of offensive linemen. One palm touching the top of the head with the elbow out to the side. 5 yards 5 yards 5 yards Intentional grounding ( offense ) A forward pass is thrown intentionally incomplete so that the passer avoids loss of yardage or to conserve time. Not assessed if the ball is spiked. If the quarterback has moved outside of the area between his offensive tackles ( the `` tackle box '' or more commonly called `` the pocket '' ), there is no foul for grounding the ball if the quarterback throws the ball past the line of scrimmage. High school is more restrictive : spiking the ball is only allowed if the quarterback is under center, and the quarterback may not legally throw the ball away when outside the `` tackle box. '' Both hands held out flat, facing each other, in front of the referee, moving down together diagonally roughly from one shoulder to the opposite hip. 10 yards or spot of foul, whichever is farther from the original line of scrimmage, and loss of down. If the foul occurs in the end zone, the play is ruled a safety. Spot of foul and loss of down ( safety if the foul occurs in the end zone ). 5 yards from the spot of the foul and loss of down ( safety if the foul occurs in the end zone ). Leaping ( defense ) A defender at least one yard in front of the line of scrimmage running forward and leaping in an attempt to block a field goal or a point - after try lands on other players on either team. The penalty is not called if the defender was within one yard of the line of scrimmage at the time of the snap. ( NCAA ) Same as Personal foul, it is a subset of that penalty. ( NFL ) Same as Unsportsmanlike conduct, it is a subset of that penalty 15 yard penalty ; automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). 15 yard penalty ; automatic first down if committed by defense ( penalty also counts regardless of how many yards the offense gained ). Leverage ( defense ) A defensive player jumping or standing on a teammate or an opponent to block or attempt to block an opponent 's kick. ( NCAA / NFL ) Same as Unsportsmanlike conduct, it is a subset of that penalty 15 yard penalty and automatic first down 15 yards Major foul ( Canada ) See personal foul, the equivalent foul in the US Neutral Zone Infraction ( defense ) Before the snap, a defensive player ( most often a lineman ) jumps into the neutral zone and `` startles '' an offensive player, causing him to false start. Same as encroachment / offsides 5 yards 5 yards 5 yards Objectionable conduct ( Canada ) See unsportsmanlike conduct, the equivalent foul in the US Offside ( offense or defense ) A player is on the wrong side of the line of scrimmage ( or in the neutral zone ) when the ball is snapped. This foul occurs simultaneously with the snap. Unlike offensive players, defensive players are not compelled to come to a set position before the snap. If a defender jumps across the line but gets back to his side before the snap, there is no foul. In the case of an offside foul, play is not stopped, and the foul is announced at the conclusion of the play. Media covering the games call it a `` free play '' for the offense, as the non-offending team may decline the penalty and take the yardage gained on the play ( and when the play works against them, like a turnover to the opposing team, the non-offending team can accept the penalty and retake possession of the ball ) - unlike in the case of a false start foul against the offense, whereupon the play is immediately stopped by the officials. This foul is almost always committed by the defense ( any offensive player that moves into the neutral zone after setting would be charged with a false start ). However, it is possible for the offense to commit this foul. If an offensive player lines up in the neutral zone, an offside foul will be called against the offense. Two hands placed on the hips 5 yards 5 yards Not applicable ( see Encroachment ) 5 yards Offside pass Any act to direct the ball forward ( toward the opponent 's dead / end line ) other than a kick or a forward pass. This includes batting the ball and forward passes after change of possession. One arm in front of chest, palm open and down, with the elbow out to the side, moved away from chest see Illegal batting or Illegal forward pass, above see Illegal batting or Illegal forward pass, above see Illegal batting or Illegal forward pass, above No yardage penalty ; the down counts, and the ball is next snapped where the pass originated Pass interference ( offense or defense ) Making physical contact with an intended receiver ( intentional physical contact in NFL ), after the ball has been thrown and before it has been touched by another player, in order to hinder or prevent him from catching a forward pass. ( On offense, the restriction begins at the snap and continues until the ball is touched in order to prevent receivers from blocking defenders away from a passed ball. ) Both arms extended in front of the body, palms upright, in a pushing motion Offense, 10 yards ; defense, spot of foul ( or placement on the 1 yard line if the foul occurs in the end zone ) and automatic first down Offense, 15 yards ; defense, lesser of 15 yards or the spot of the foul ( or placement on the 2 yard line if the foul occurs in the end zone ) and automatic first down 15 yards, regardless of whether or not the foul is in the end zone.
