Triple crown: Tyson was the first heavyweight boxer to hold the WBA, WBC, and IBF titles simultaneously. He is thought by many to be one of the greatest heavyweights of all time. However, he lost his titles to James "Buster" Douglas on Feb. 11, 1990, in Tokyo, even though Douglas was a 42-to-1 underdog.
Quick to the punch: Tyson won his first 19 professional fights by way of knockout. Also, 12 of those knockouts came in the first round. By the late 1980s he unified the belts in the splintered heavyweight division to become the undisputed heavyweight champion of the world. He went on to become the lineal champion after defeating Michael Spinks in the first 91 seconds of the fight.
Tyson-Holyfield: On Nov. 9, 1996, in Las Vegas, Tyson and Evander Holyfield faced off for the first time in their careers with the WBA title on the line. Tyson was heavily favored in this contest; however, Holyfield went on to defeat Tyson by TKO in the 11th round. With the upset, Holyfield became the only other person besides Muhammad Ali to win a heavyweight championship three times. Holyfield's frequent head butts were heavily discussed after the fight and they would come into play when Tyson and Holyfield met for the second time on June 28, 1997. This rematch saw the highest-paid professional boxing purses ever up until 2007, with Tyson receiving $30 million and Holyfield receiving $35 million. This bout would become one of the most controversial events in modern sports. The fight was stopped by referee Mills Lane in the third round. Tyson was disqualified for biting Holyfield on both ears. The second bite was severe enough to remove a small piece of Holyfield's ear, which was found on the ring after the fight ended. Tyson claims he did it in retaliation to Holyfield's continuous head butts.
