Mouthpiece rule.
All contestants are required to wear a mouthpiece during competition. The round cannot begin without the mouthpiece. If the mouthpiece is dislodged during competition, the referee will call time and have the mouthpiece replaced at the first opportune moment, without interfering with the immediate action. The referee may deduct points if it is judged the mouthpiece is being purposely spit out.
