No! There are some notable instances in boxing and MMA where you won’t get penalized or disqualified for making rabbit punches. Let’s show you a perfect scenario where a rabbit punch might not be considered illegal during a fight. If a fighter gets a strike at the back of the head as he turns his back to the attack from his opponents who unknowingly is throwing a barrage of punches to achieve a knockout, then he can’t be penalized for making a rabbit punch as it wasn’t intentional. Such a fighter would be pardoned because he was only trying to aim for the face and the opponent turned his back to receive the hit at the back of the back.
