On February 11, 1990, Buster Douglas, a 42-1 underdog, knocked out Mike Tyson in the 10th round of their 12-round fight to complete one of the biggest upsets in boxing history. While always thought of as a decent fighter, Douglas was given practically no chance by oddsmakers, writers, and fans alike, as Tyson was on an incredible run, building up a 37-0 record up until this point. Douglas would lose his heavyweight title in his next fight to Evander Holyfield on a third-round knockout. Douglas would retire after losing to Holyfield, coming back for a short time in 1996, retiring again in 1999.
