Fight stoppers are two important roles in the sport of boxing. Referees, or REFS, are responsible for ensuring that the rules of the sport are followed and that the boxers are safe. They also have the authority to stop a fight if they deem it necessary. TKOS, or Technical Knockouts, are when a boxer is unable to continue fighting due to injury or exhaustion. This can be declared by the referee or the ringside doctor. Both REFS and TKOs are important in boxing as they help to ensure the safety of the boxers.
