Quick Summary

In boxing, a knockout (KO) occurs when a boxer is knocked down and cannot rise to their feet before the referee counts to ten. A technical knockout (TKO) is when a referee stops the fight because a boxer is unable to continue, often due to injury or being unable to defend themselves. This can also happen if a boxer or their corner decides to stop the fight. Both KOs and TKOs result in an immediate loss for the affected boxer.123
