In the event that a boxer loses his or her mouthpiece, the referee shall call time during a lull in the action of the contest and cause such boxer's seconds to install a backup mouthpiece or promptly wash and reinstall the same mouthpiece. If a referee determines that a boxer has deliberately spit out his or her mouthpiece for any reason, the referee may issue a warning to such boxer or deduct one or more points from such boxer and, upon any subsequent such infraction, may disqualify the boxer by declaring the opponent a winner.
