Mike Tyson vs. Carl Williams was a professional boxing match contested on July 21, 1989, for WBA, WBC, IBF, and The Ring heavyweight championships.

[1] After Tyson's dominating victory over Frank Bruno five months prior, negotiations for a potential bout with Carl Williams began, and on June 15, 1989, the fight was made official.

[2][3] Four years earlier, Williams had challenged then-IBF Heavyweight champion Larry Holmes for the title, only to narrowly lose by unanimous decision.

His eyes were blank, his expression was blank, he had no answer.”[5] Because of the controversial nature of Tyson's victory, both Williams and his manager Ira Leibowitz urged the WBA, WBC and IBF to change the ruling Tyson victory to no-contest while also demanding a rematch between the two.

HBO, which broadcast the fight live across the nation, did not expect the early conclusion and was hence forced to fill time with episodes of The Kids In The Hall and HBO One Night Stand (prior to the latter, they put up a card explaining the unscheduled broadcast).
