Approved Ruling 1-4-2:I
I. The Team A player who started the game wearing jersey number 77 enters the game wearing number 88. RULING: The player must report to the referee who, without stopping the game or play clock, announces the change (using their microphone if available) and the relevant sideline official informs the opposing head coach. If A88 fails to report it is a foul for unsportsmanlike conduct. [Cited by 1-4-2-d]
