58 Pa. Code § 29.14 – Accidental fouls.

(a) If a contest or exhibition of professional mixed martial arts is stopped because of an accidental foul, the referee, with advice from the ringside physician, shall determine whether the contestant who has been fouled can continue or not. If the contestant’s chance of winning has not been seriously jeopardized as a result of the foul, the referee may order that the contest or exhibition continue after a recuperative interval of not more than 5 minutes. Immediately after separating the contestants, the referee shall inform the Commission’s representative of a determination that the foul was accidental.
(b) If the referee determines that a contest or exhibition of professional mixed martial arts may not continue because of an injury suffered as the result of an accidental foul, the contest or exhibition shall be declared a no contest if the foul occurs during either of the following:
1. (1) The first two rounds of a nonchampionship contest or exhibition.
2. (2) The first three rounds of a championship contest or exhibition.
(c) If an accidental foul renders a contestant unable to continue the contest or exhibition after the completed second round of a nonchampionship contest or exhibition, or after the completed third round of a championship contest or exhibition, the outcome shall be determined by scoring the completed rounds and the round during which the referee stops the contest or exhibition.
(d) 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 shall be determined by scoring the completed rounds and the round during which the referee stops the contest or exhibition.
