Mike Tyson vs James "Buster" Douglas produced one of the greatest upsets in boxing history at the Tokyo Dome in 1990. Tyson, the undefeated heavyweight champion, appeared to be on course for another victory when he knocked Douglas down in the eighth round, but the challenger recovered brilliantly and continued to outbox Tyson. Douglas dominated much of the contest before finishing the job in the tenth round, dropping Tyson for the first time in his professional career and ending his reign as undisputed heavyweight champion with a stunning knockout victory.
