Southern California is imposing sanctions on its basketball program for violating NCAA rules involving former player O.J. Mayo.

The university's investigation found rules were violated during Mayo's one season with the Trojans in 2007-08 under former coach Tim Floyd. Mayo currently plays for the NBA's Memphis Grizzlies.

The sanctions announced yesterday call for a one-year ban on postseason play following the current regular season, including the Pac-10 Conference tournament; a loss of one scholarship for this season and the 2010-2011 season; a loss of one coach permitted to engage in off-campus recruiting during the summer of 2010; and the loss of 20 recruiting days (from 130 to 110) for the 2010-2011 academic year.

The school said that because of Mayo's involvement with Rodney Guillory, who under NCAA rules became a USC booster due to his role in Mayo's recruitment, USC will vacate its 21 victories during the 2007-08 season, when Mayo competed while ineligible.

Floyd abruptly quit in June following allegations that he gave $1,000 in cash to Guillory who helped steer Mayo to the Trojans.

Floyd is now an assistant with the New Orleans Hornets.

Louis Johnson, a former associate of Mayo and Guillory, has previously alleged Guillory received hundreds of thousands of dollars from a sports agency that he partially funneled to Mayo.

USC will return to the NCAA the money it received through the Pac-10 for playing in the 2008 NCAA tournament. The Trojans lost in the first round to Kansas State.

"When we've done something wrong, we have an obligation to do something about it and that is exactly what we are doing here," USC athletic director Mike Garrett said in a statement.

Kevin O'Neill took over for Floyd and has guided the Trojans to a 10-4 record and an eight-game winning streak. The Trojans won the Hawaiian Airlines Diamond Head Classic, Dec. 22, 23 and 25 at the Stan Sherif Center.
