The fight was marred in a controversy after Mosley's trainer, Naazim Richardson diligently spotted a gauze knuckle pad accessory in Margarito's hand wraps. California State Athletic Commission officials had Margarito re-wrap his hands and took the pad for testing: a state laboratory likened the substance to plaster of Paris. Margarito and trainer Javier Capetillo would be suspended for a year by CSAC: this effectively banned them from boxing across the United States, as suspensions in one state are usually also enforced by other commissions. Later investigations determined that Margarito was likely loading his gloves for several other fights as well, including his title win over Miguel Cotto.
