July 21, 1989: Mike Tyson knocks out Carl (The Truth) Williams in just 93 seconds to retain the undisputed heavyweight championship.
The fight did have some controversy. Referee Randy Neumann stopped the fight and awarded Tyson the victory by technical knockout even though Williams was able to return to his feet and was seemingly ready to continue fighting.
The decision upset Williams so much that he and his agent demanded that that the victory be declared a no contest and that a rematch was put together. Williams' complaints' fell on deaf ears as he was never granted his rematch, and the decision stood.
This fight marked Tyson's last successful title defense. Tyson, 23, went on to get knocked out by James "Buster" Douglas in the tenth round on Feb. 11, 1990, in one of the biggest upsets in boxing history.
