The role of referees in combat sports is critical for ensuring fair play and maintaining safety during matches. Referees are responsible for enforcing the rules, monitoring the fighters' actions, and intervening when necessary to prevent injury. They also have the authority to stop a match if one fighter is in danger or unable to defend themselves appropriately. Referees must possess a deep understanding of the sport, as their decisions directly impact the outcome of the fight and uphold the integrity of the competition.
