No professional boxer or professional mixed martial artist shall participate in any contest or exhibition following weight loss of one percent or more of body weight within 24 hours prior to such contest or exhibition, unless otherwise authorized by the commission. A combatant may be disapproved for participation in a match or exhibition if, in the professional medical opinion of the reviewing physician, it would be unsafe for the combatant to compete in the match or exhibition due to a finding of dehydration or extreme weight loss.
