"Leon Spinks" is an American former boxing/boxer, who had an overall record of 26 wins, 17 losses and three draws as a professional boxing/professional, with 14 of those wins by knockout. In only his eighth professional bout, Spinks won the Undisputed Champion/undisputed world list of heavyweight boxing champions/heavyweight championship when he beat Muhammad Ali on February 15, 1978, in what was considered one of the biggest upsets in boxing history. However, he was stripped of the World Boxing Council/WBC title for fighting Ali in an unapproved rematch seven months later, which he lost by a 15-round unanimous decision. Besides being heavyweight champion and his characteristic gap-toothed grin (due to losing two and later all four of his front teeth), Spinks gained notoriety for the disaster which befell his career following the loss to Ali.If you enjoy these quotes, be sure to check out other famous athletes!
