When may the scorer signal?
If the scorer desires to call attention to a player who is illegally in the game, he/she may signal the official when the ball is in control of that player’s team. If it is for a substitution, the scorer may signal when the ball next becomes dead and the clock is stopped. If it is for conferring with an official, he/she may signal when the ball is dead. If the scorer signals while the ball is live, the official should ignore the signal if a scoring play is in progress. Otherwise, the official may stop play to determine the reason for the scorer’s signal.
