A1 fouls B1. The official who made the ruling moves toward the reporting area. A2 immediately signals the free official for a time-out. Momentarily thereafter, the scorer notifies the ruling official that A1 has fouled out.
A1 must be replaced before the time-out is granted. COMMENT: The first responsibility the ruling official has is to report the foul to the scorer. Officials should not be hasty in granting an immediate time-out after the game has reached a point that players may begin to foul out. Rather, they should take a second or two after reporting the foul to see if the scorer may report a disqualification.
