On This Day in Sports: February 11, 1990
On February 11, 1990, James “Buster” Douglas knocked out Mike Tyson in the tenth round at the Tokyo Dome, producing one of the greatest upsets in sports history. Tyson arrived as the undefeated and undisputed heavyweight champion, feared for his speed, power and string of early knockouts. Douglas was widely treated as an opponent expected to lose, with betting odds commonly listed around 42–1 against him.
Douglas refused to fight cautiously. He used a long jab to control distance, followed with combinations and tied Tyson up when the champion moved inside. Round after round, he disrupted the rhythm that had overwhelmed Tyson’s previous opponents. Douglas was carrying personal grief after the recent death of his mother, yet he appeared focused and physically prepared while Tyson’s corner struggled to respond to the swelling around his eye.
Tyson finally landed a crushing uppercut late in the eighth round and dropped Douglas. Douglas rose before the referee completed the count, then recovered during the break. In the tenth, he connected with an uppercut of his own and followed with a rapid combination that sent Tyson down. The champion searched for his mouthpiece and could not regain his feet before the count ended.
The knockout ended Tyson’s 37-fight unbeaten run and made Douglas the world heavyweight champion. Debate followed over the count Douglas received in the eighth, but the result stood because the referee’s count—not a stopwatch—governs the action. More broadly, the fight became proof that reputations and odds cannot decide a contest. Douglas’s discipline under pressure turned an expected showcase into boxing’s enduring symbol of possibility.
