Michael Spinks
Michael Spinks (born July 13, 1956) is an American former boxer who was an Olympic gold medalist and world champion in the light-heavyweight and heavyweight divisions. Nicknamed Jinx, which spawned the nickname of his right hand: The Spinks Jinx, he is the brother of former heavyweight champion Leon Spinks, and uncle of Cory Spinks, a former welterweight and light middleweight champion. He is also one of only five people, along with Mike Tyson, Evander Holyfield, Oliver McCall and Brian Nielsen to defeat Larry Holmes and the only one to do it twice.
After a successful amateur career, which culminated in him winning a gold medal at the 1976 Olympics, Spinks went undefeated in his first 31 professional fights, beating such opponents as Dwight Muhammad Qawi, Eddie Mustafa Muhammad, Marvin Johnson and Eddie Davis en route to becoming undisputed world light-heavyweight champion. Following ten successful title defences, Spinks moved up to heavyweight and as underdog beat the long-reigning IBF heavyweight champion Larry Holmes; in doing so, Spinks became the first reigning light-heavyweight champion to win the heavyweight title. In his final fight, Spinks was knocked out by Mike Tyson in 91 seconds, the only defeat of his professional career.
