Do any of the answerers know this to be the approved NFHS ruling, or simply venturing a guess?

ASA would rule the force removed when the BR was later put out, rendering the subsequent appeal a timing play. NCAA would consider the appeal a force out, because their rule relates to "forced to advance at the time of the infraction", not the time of the appeal. I don't see either stated in the NFHS rule book.

Both NFHS and NCAA would allow a defensive team to substitute a beneficial fourth out; ASA would not, since the appeal wasn't on a runner that scored.

So, I repeat;

Do you know, or simply stating your opinion as if it were fact? Citation from NFHS, please.
