Technical knockout refers to a situation in combat sports where a fighter is declared the winner because their opponent has become unable to continue due to technical reasons. There are several synonyms for the term, including stoppage, TKO, technical decision, technical victory, and technical stoppage. In some cases, a referee may stop a fight when they notice a fighter is receiving a series of unanswered blows, or the fighter is not intelligently defending themselves, resulting in a technical knockout. Synonyms for technical knockouts are commonly used in boxing, mixed martial arts, kickboxing, and other combat sports to describe events where a fighter has won without knocking out their opponent.
