bruce lee:
Fight history
Lee was involved in competitive fights, some of which were arranged while others were not. Dan Inosanto stated, "There's no doubt in my mind that if Bruce Lee had gone into pro boxing, he could easily have ranked in the top three in the lightweight division or junior-welterweight division".[42]
Lee defeated three-time champion British boxer Gary Elms by way of knockout in the third round in the 1958 Hong Kong Inter-School amateur Boxing Championships by using Wing Chun traps and high/low-level straight punches.[43]
The following year, Lee became a member of the "Tigers of Junction Street," and was involved in numerous gang-related street fights. "In one of his last encounters, while removing his jacket the fellow he was squaring off against sucker punched him and blackened his eye. Bruce flew into a rage and went after him, knocking him out, breaking his opponent's arm. The police were called as a result".[44] The incident took place on a Hong Kong rooftop at 10 pm on Wednesday, 29 April 1959.[45] In 1962, Lee knocked out Uechi, a Japanese black belt Karateka, in 11 seconds in a 1962 Full-Contact match in Seattle. It was refereed by Jesse Glover. The incident took place in Seattle at a YMCA handball court. Taki Kamura says the battle lasted 10 seconds in contrary to Hart's statement.[46] Ed Hart states "The karate man arrived in his gi (uniform), complete with black belt, while Bruce showed up in his street clothes and simply took off his shoes. The fight lasted exactly 11 seconds – I know because I was the time keeper – and Bruce had hit the guy something like 15 times and kicked him once. I thought he'd killed him".[47]
