Piggy-backing with the previous, check with your state for two inevitable things:
1) Their specific penalties regarding eligibility in upcoming games for unsportingly disqualified players (2 T's or a flagrant foul) and ejected adult bench personnel which the NFHS does not stipulate, and
2) Wording in their official documents which blurs the distinction, well-expressed in the NFHS books, between "disqualification" and "ejection".
Our state does both. Quite well.
