Mosley and De La Hoya faced each other for the second time on September 13, this time with De La Hoya's "The Ring", WBC, WBA and lineal light middleweight championships on the line. Mosley defeated De La Hoya by a controversial 12 round unanimous decision and joined the exclusive group of world boxing champions that have reigned in three or more divisions. Many fans had Oscar easily beating Mosley in this rematch but judges scored it differently regardless of De La Hoya landing over 100 more punches. Mosley testified in 2003 that he injected himself with the notorious doping agent EPO as he prepared for his light-middleweight title fight against Oscar De La Hoya, according to grand jury transcripts and doping calendars.
