During their possession in the 2nd OT period, Team B has scored a touchdown, to bring the score to 64-66, Team A leading. On the try, the snapper sends the ball over the head of the holder A12, who recovers the ball and manages to run into the end zone. B38 punches A22 and throws him to the ground as A12 enters the end zone.
Also, same play, but no fouls occur.
Ruling?
Primarily interested in philosophy/how it is handled when H/L have forward progress/TD or not, but don't see the foul, and the U/R that have the foul, aren't sure of the location of the runner when foul occurred, how to determine dead ball foul or live ball foul. Matters quite a bit in this scenario.
