Does anyone read the NFHS interps?
2005-06 NFHS Basketball Rules Interpretations
SITUATION 1: A1 is fouled by B1 late in the second quarter. It is a common foul and the seventh Team B foul. The bonus situation is not recognized by the scorer or the officiating crew, and the Team A coach substitutes A6 for A1. A6 is beckoned onto the floor and A1 goes to the team bench. The scorer recognizes the error and sounds the horn (a) just before or (b) just after the administering official hands the ball to A2 for a throw-in. RULING: This is a correctable-error situation and falls within the proper timeframe for a correction. In both (a) and (b), A6 leaves the game with A1 re-entering to shoot the bonus free throw. Play is resumed as after any free-throw attempt(s). If the second free throw is successful and the coach desires, A6 may re-enter the contest. (2-10-1a; 2-10-6)
