523 CMR 16.05
Fouls: Accidental
(1) If a contest or exhibition 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. A
recuperative interval of not more than five minutes is allowed for groin fouls only. Immediately after
separating the unarmed combatants, the referee shall inform the Commission of his determination that
the foul was accidental.
(2) If the referee determines that a contest or exhibition of mixed martial arts may not continue
because of an injury suffered as the result of an accidental foul, the contest or exhibition must be
declared a no decision if the foul occurs during:
(a) The first two rounds of a contest or exhibition that is scheduled for three rounds or less; or
(b) The first three rounds of a contest or exhibition that is scheduled for more than three rounds.
(3) If an accidental foul renders an unarmed combatant unable to continue the contest or exhibition
after:
(a) The completed second round of a contest or exhibition that is scheduled for three rounds or
less; or
(b) The completed third round of a contest or exhibition that is scheduled for more than three
rounds,
the outcome must be determined by scoring the completed rounds and the round during which the
referee stops the contest or exhibition if that round is more than half way complete.
(4) If an injury inflicted by an accidental foul later becomes aggravated by fair blows and the referee
orders the contest or exhibition stopped because of the injury, the outcome must be determined by
scoring the completed rounds and the round during which the referee stops the contest or exhibition.
