The play described below is provided for your review and discussion. The rulings given are based on NFHS rules. NCAA rulings may be different.
A1 is fouled in the act of shooting by B1 and awarded two free throws. After the first free throw, the Center official notices that A1 is bleeding from his nose. The coach of Team A is notified and made aware of his options to substitute for A1, take 20 seconds to clean/stop the blood, or request a timeout. The coach of Team A decides to substitute A6 for A1. A6 is beckoned onto the court by the referee.
While the blood is being cleaned from the floor, the coach of Team A changes his mind and wants to substitute A7 for A6.
Handle the situation.
