“Mixed martial arts” means unarmed combat involving the use, subject to any applicable   limitations set forth in these Unified Rules and other regulations of the applicable Commission, of a combination of techniques from different disciplines of the martial arts, including, without limitation, grappling, submission holds, kicking and striking.

“Unarmed Combat” means any form of competition in which a blow is usually struck which may reasonably be expected to inflict injury.

“Unarmed Combatant” means any person who engages in unarmed combat.

“Commission” means the applicable athletic commission or regulatory body overseeing the bouts, exhibitions or competitions of mixed martial arts. 

 

Except with the approval of the Commission, or its executive director, the classes for mixed martial arts contests or exhibitions and the weights for each class shall be:

Flyweight  125 pounds and under
Bantamweight  over 125 to 135 pounds

In addition, if one athlete weighs 264 pounds while the opponent weighs 267 pounds, the Commission may still decide to allow the contest if it determines that the contest would still be fair, safe and competitive in spite of the fact that the two contestants technically weighed in differing weight classes.

    2. a round is to be scored as a 10-9 round when a contestant wins by a close margin, landing the greater number of effective legal strikes, grappling and other maneuvers;
    3. a round is to be scored as a 10-8 round when a contestant overwhelmingly dominates by striking or grappling in a round.
    4. a round is to be scored as a 10-7 round when a contestant totally dominates by striking or grappling in a round.
  11. Judges shall use a sliding scale and recognize the length of time the fighters are either standing or on the ground, as follows:
    1. if the mixed martial artists spent a majority of a round on the canvas, then:
      1. Effective grappling is weighed first; and
      2. Effective striking is then weighed
    2. If the mixed martial artists spent a majority of a round standing, then:
      1. Effective striking is weighed first; and
      2. Effective grappling is then weighed
    3. A round is to be scored as a 10-8 round when a contestant overwhelmingly dominates by striking or grappling in a round.
    4. If a round ends with a relatively even amount of standing and canvas fighting, striking and grappling are weighed equally.

    3. If the fighter goes over the 5 minute time allotment, and the fight cannot be restarted, the contest must come to an end with the outcome determined by the round and time in which the fight was stopped. See Section 16 below.
  8. Fighter Fouled by other than low blow:
    1. If a contest of mixed martial arts is stopped because of an accidental foul, the referee shall determine whether the unarmed combatant who has been fouled can continue or not. If the unarmed combatant's chance of winning has not been seriously jeopardized as a result of the foul and if the foul did not involve a concussive impact to the head of the unarmed combatant who has been fouled, the referee may order the contest or exhibition continued after a recuperative interval of not more than 5 minutes. Immediately after separating the unarmed combatants, the referee shall inform the Commission's representative of his determination that the foul was accidental.
    2. If a fighter is fouled by blow that the referee deems illegal, the referee should stop the action and call for time.

    3. For a foul other than a low blow, if the injured fighter is deemed not fit to continue, by the referee, the referee must immediately call a halt to the bout. If the fighter is deemed not fit to continue, by the referee, even though some of the 5 minute foul time is still remaining, the fighter cannot avail himself of the remaining time and the fight must be stopped.
    4. If the referee stops the contest and employs the use of the ringside doctor, the ringside physician's examinations shall not exceed 5 minutes. If 5 minutes is exceeded, the fight cannot be re-started and the contest must end.

If the injured contestant is even or behind on the score cards at the time of stoppage, the outcome of the bout shall be declared a technicaldraw.
  5. If a contestant injures himself or herself while attempting to foul his or her opponent, the referee shall not take any action in his or herfavor, and the injury shall be treated in the same manner as an injury produced by a fair blow.
