On January 3, 2010, USC announced that it had determined Mayo was ineligible for the 2007–2008 season because he received improper benefits, and had thus forfeited his amateur status before ever playing a game for USC. As a result, USC vacated all 21 of its wins from the 2007–08 season, dropping its record to 0–12. A vacated game does not count as a win for the other team, but is officially treated as having never happened. USC also withdrew from postseason consideration (including the Pac-10 conference tournament) for the 2009–10 season.
