James "Buster" Douglas is a former undisputed world heavyweight boxing champion who scored a stunning upset when he knocked out previously undefeated champion Mike Tyson on February 11, 1990, in Tokyo, Japan. At the time, Tyson was considered to be the best boxer in the world and one of the most feared heavyweight champions in history due to his utter domination of the division. The Mirage Casino in Las Vegas, the only Las Vegas casino to make odds on the fight, had Douglas as a 42 to 1 underdog for the fight, making his victory, in commentator Jim Lampley's words, "Let's go ahead and call it. The biggest upset in the history of heavyweight championship fights!" Douglas held the title for eight months and two weeks, losing on October 25, 1990, to 28-year-old, 6-foot-2-inch, 208-pound Evander Holyfield, via third-round KO, in his only title defense.
