fumble, then penalty, then run

[jTheUmp]

A will decline the penalty for the Facemask, and accept the result of the play.

1st and 10 for A at the B-20.

A could also accept the penalty from the basic spot: the end of the related run at the 50 yard line, giving them first and 10 from the B-45 (for a 5-yard FM) or from the B-30 (for a 15-yard FM), but I don't see any sane Team A coach choosing that option.

All of these are assuming that, if we're operating under FED rules, the run and/or penalty enforcement places the ball beyond the line-to-gain, as there is no AFD provision for FM fouls in FED.
