MEMPHIS, Tenn. — The NBA has suspended guard O.J. Mayo 10 games without pay for violating the league and union's anti-drug program with a positive test.

MEMPHIS, Tenn. — The NBA has suspended guard O.J. Mayo 10 games without pay for violating the league and union's anti-drug program with a positive test.

The league announced the suspension Thursday for Mayo's positive test for dehydroepiandrosterone (DHEA). Mayo's suspension will start tonight when the Grizzlies visit Philadelphia, and he will be able to return Feb. 15 also against the 76ers in Memphis.

Mayo said in a statement released by the team that he is extremely disappointed he will miss 10 games as the Grizzlies are making a push for the playoffs. He blamed an over the counter supplement that he didn't know was banned by the NBA for the positive test, but a team spokesman said Mayo declined to say which supplement he used.

Mayo was the No. 3 pick overall in 2008 after only one season at USC, and Minnesota swapped him draft night deal to the Grizzlies for Kevin Love. Mayo was runner-up to Chicago's Derrick Rose for rookie of the year.

But the guard was moved to the bench earlier this season, starting just 15 of Memphis' 45 games this season. He's been bandied about as possible trade bait.
