Twenty-five years ago today – Feb. 10, 1990 (Feb. 11 in Japan) – James “Buster” Douglas knocked out heavyweight champion Mike Tyson in the 10th round in Tokyo, Japan to shock the world in perhaps the biggest upset in history in a big fight.

Douglas survived an eighth-round knockdown to come back and sock it to Tyson in a way that will always be remembered.
