When the disc goes out of bounds, play is resumed where it crossed the line, if it goes out the back, walk it to the closest spot on the end line. Throwing team gains possession if the receiving team touches the disc in the air and drops it. If the pull lands out of bounds, receiving team has a choice of taking disc on sideline, where it went out, or in the middle of the field at the point where it went out. If the pull goes out of the back of the endzone the receiving team starts play at the five yard line. If you gain possession in the end zone you are attacking, you must walk the disc perpendicularly back to the goal line.
Fouls are the result of physical contact between opposing players.
A foul can only be called by the player who was fouled. It must be called immediately after the occurrence. On uncontested catching fouls, the receiver takes the disc as if caught. Check the disc. On offensive fouls or travels, it stays the same or goes back to six, whichever is lower.
