Michael Spinks of his professional career. Spinks has been inducted into the International Boxing Hall of Fame and the World Boxing Hall of Fame. The International Boxing Research Organization and BoxRec rank Spinks among the ten greatest light heavyweights of all time. Spinks won the 1974 156-pound Golden Gloves Light Middleweight Championship by defeating Wilber Cameron in Denver, Colorado and then took the Silver Medal in the National AAU 165-pound Championship Competition in 1975, losing in three rounds to Tom Sullivan in Shreveport, Louisiana. He rebounded to take the 1976 National Golden Gloves Middleweight championship with a three-round victory over Lamont Kirkland
Leon Spinks to Norton. His second match with Ali, at the Louisiana Superdome on September 15, 1978, went badly for Spinks. A now-in-shape Ali—with better, sharper tactics—rarely lost control, winning back his title by a unanimous fifteen-round decision. Ali regained the title, becoming the first three-time lineal heavyweight champion. Spinks was never given a rematch; Ali retired after the fight (although he came out of retirement a few years later to fight Larry Holmes and Trevor Berbick). Spinks's next fight, his only one in 1979, was at Monte Carlo, where he was knocked out in the first round by future WBA world
