what is the meaning of tko in boxing
Knockout A technical knockout (TKO or T.K.O.), or stoppage, is declared when the referee or official ring physician decides during a round that a fighter cannot safely continue the match for any reason, without the need for an intervening count. In most regions, a TKO is declared when a fighter is knocked down three times in one round.[3] Other reasons for stopping a fight include severe facial lacerations and a fighter's inability to put up a sufficient defense following a knockdown.
Professional boxing In contrast with amateur boxing, professional bouts are typically much longer and can last up to twelve rounds, though less significant fights can be as short as four rounds. Protective headgear is not permitted, and boxers are generally allowed to take substantial punishment before a fight is halted. Professional boxing has enjoyed a much higher profile than amateur boxing throughout the 20th century and beyond.
