Newbies please note. Even after being "seatbnelted", a coach may still stand in a few situations:
The head coach may stand within the coaching box to request a time-out or signal players to request a time-out, to confer with personnel at the scorer’s table to request a time-out for a correctable error, or a timing, scoring or alternating-possession mistake be prevented or rectified, to replace or remove a disqualified/injured player or player directed to leave the game, during a charged time-out, or the intermission between quarters and extra periods, to spontaneously react to an outstanding play by a team member or to acknowledge a replaced player, but must immediately return to his seat.
