Match officials are individuals responsible for enforcing the rules of a sport during a game. They include referees, umpires, and linesmen, depending on the sport. Their primary role is to ensure fair play, make decisions on fouls or violations, and maintain the flow of the game. In many sports, match officials are trained professionals who undergo rigorous testing and certification. They often use tools like video assistant referees (VAR) in soccer or instant replay in American football to assist in making accurate decisions. Their authority is crucial for upholding the integrity of the game.
