Cutman

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 (commonly called cuts). The rules of full contact 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.
The compensation for cutmen varies, generally staying within 1-3% of fighter's prize money. For many fighters on a low budget, the cutman duties are performed by their cornerman. While most athletic commissions require cutmen to be licensed, there is usually no formal training or certification required. Most cutmen learn their trade through apprenticeship and self-education.
Unlike boxing, cutmen for mixed martial arts events are generally provided by the promotion, rather than the fighter's corner. This is to prevent allegations of "greasing" (applying petroleum jelly to areas other than the forehead, which provides an unfair advantage in grappling situations).
Cutmen should not be confused with the fight doctor who is an official that monitors the health of the fighters, and whose task is closer to that of neutral referees, providing medical advice and monitoring the safety of both fighters in accordance with regulations or law and evaluates their ability to continue fighting.
