American Football NCAA Approved Ruling 10-1-5
I. With fourth and eight, Team A gains four yards and the ball is declared dead, after which B1 is called for piling on. RULING: Team B personal foul. Penalty—15 yards from the succeeding spot. First and 10 for Team B (Rule 5-1-1-c). The clock starts on the snap.
II. A personal foul occurs during action after a snap infraction that was made before the ball was ready for play. RULING: Every effort should be made to prevent any such premature snap and resulting action, but if such a foul does occur, it is between downs. Both penalties are enforced. If the personal foul is by Team B, there is likely a net of 10 yards for Team A. The penalty for Team B’s foul carries an automatic first down.
III. Second and goal at the three-yard line. Ball carrier A14 is downed at the one-yard line and then B67 piles on. A14 retaliates by punching B67. RULING: The penalties cancel since neither has been completed. A14 is ejected for fighting. Third and goal (Rule 10-1-1).
