[MRH]

R1 is preparing to catch a scrimmage kick in flight by K. K1 begins his charge to contact R1. In the brief moment before the catch R1 signals for a fair catch, makes the catch and is then contacted by K1. Since the fair catch signal was given after K1 began his charge does a personal foul occur?

In other words, is there any such thing as a fair catch signal being given too late?

I'm not finding anything in the NFHS book to support NOT calling a foul.

Primarily looking for the NFHS ruling but would like to know NCAA as well.
