A cutman is a person responsible for preventing and treating physical damage to a fighter during the breaks between rounds of a full contact match such as a boxing, kickboxing or a mixed martial arts bout. Cutmen typically handle swelling, nosebleeds and lacerations. In addition to degrading a fighter's performance, the rules of combat sports stipulate that these injuries can be a cause for premature match stoppage, counting as a loss to the injured fighter. The cutman is therefore essential to the fighter, and can be a decisive factor in the outcome of the match.
