Once a team has made their choice on the extra point, they can only change their decision by taking a time-out. If a player carries the ball across the goal line they are defending and the ball becomes dead while in their team's possession, it is a safety. If a team commits a foul in the end zone where the spot of enforcement is designated as the spot of the foul, it will be declared a safety. A team recording a safety will receive two points and the ball at their own 15 yard line. When a player intercepts a forward pass or catches a scrimmage kick between their five yard line and their goal line and their momentum carries them into the end zone where the ball becomes dead, the ball will belong to the receiving team at the spot of the catch or reception.
Any act listed below or any other act of unnecessary roughness is a personal foul.
Contact an opponent either before or after the ball is declared dead. Clip an opponent. Tackle the runner. Screen blocking shall take place without contact. The blocker shall have their hands and arms at their sides or behind their back.
