CYO Varsity Girls (7th/8th Grade) -- NFHS Rules.
Visiting team had a player get fouled hard and complains her wrist hurts and she can't shoot her free throws. The official tells the visiting coach if she's replaced, she can't re-enter the game at all.
I know if an injured player is judged to have a concussion, her or she can't come back without approval from a DO or MD, but for a non-concussion injury, is the above true, or is it some sort of rule myth?
