American Football Rules IFAF Approved Ruling 8-3-3:I
I. During a try attempt, Team A’s legal kick, untouched and in the air, has crossed the neutral zone when a foul occurs. RULING: If the foul is by Team A and the try is unsuccessful, and Team B does not gain possession, the try ends. If the foul is by Team A and the try is successful, the penalty is at the previous spot. If the foul is by Team B and the try is successful, score the point unless Team A chooses to accept the penalty and attempt a two-point play. The try is exempt from postscrimmage kick enforcement. Penalties for Team B personal fouls on a successful try may be enforced on the subsequent kickoff or at the succeeding spot in extra periods. If the try is unsuccessful, Team A may accept the penalty and the down will be repeated. [Cited by 8-3-3-b-1, 8-3-3-c-1]
