[4] Instead, it was announced in March that Mayweather would be matched up against replacement opponent, former WBO junior welterweight champion DeMarcus Corley.

[5] Corley had not fought since losing his title to Zab Judah 10 months prior, but denied that the length layoff would effect him as he had partaken in the training camps of Ricardo Mayorga and Kostya Tszyu as a sparring partner since his last fight.

Corley was aggressive and attempted to press the action during the early portion of the fight and managed to stagger Mayweather in the third and fourth rounds, but over the course of the fight, Mayweather used his superior defense to keep Corley off balance and effectively counter-punched.

Corley was down on the canvas seven times during the bout, though only two were official knockdowns while the remainder were ruled slips or pushes.

The first knockdown came in the eighth round after a Mayweather combination forced a tired Corley to take a knee.
