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

The university said Sunday its 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 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 20 less recruiting days (from 130 to 110) allowed for the 2010-2011 academic year.

USC won the inaugural Diamond Head Classic in Honolulu last month.
