foul in overtime

[ppaltice]

Scoring play is not the correct terminology, because there are a few ways you can score (TD, try, FG, and safety). Each have their on provisions for fouls that occur during the play.

The OP specified touchdown. On a foul by the defense that occurs during a TD, the penalty may be assessed on either the try or the subsequent kickoff. If the foul occurs during OT, there is no subsequent KO, so the penalty can only be assessed on the try (Rule 8-2-2).

If the penalty by the defense occurred during a successful try, A has the option of having the penalty assessed on the try and replaying or on the succeeding spot (which means it can carry over to the next series in OT) (Rule 8-3-5).

If the penalty by the defense occured during a successful FG, A has the option of having the penalty assessed from the previous spot and replaying the down or having the penalty assessed on the succeeding spot (next series in OT) (Rule 8-4-3).

No carryover provisions for penalties that occur during a safety (although quarter will not be extended for the kickoff).

Make sense? I think you are trying to bundle all scoring plays into one, and that is just not supported by rule.
