"The NBA announced today that Grizzlies guard O.J. Mayo has been suspended without pay for 10 games for violating the terms of the league's anti-drug program.

His violation of the program involved a positive test for dehydroepiandrosterone. DHEA is commonly available in health food stores and pharmacies. It is a steroid hormone that acts on the body much like testosterone.

Mayo's suspension will begin with Friday's game against the Philadelphia 76ers. Mayo will be eligible to return Feb. 15 when the Griz host the Sixers.

"I'm extremely disappointed that I'm going to miss the next 10 games, particularly as our team is making a push for the playoffs," Mayo said in a statement. "I had no idea that the over-the-counter supplement that I took was a substance banned by the NBA. It was an honest mistake, but I take full responsibility for my actions. I apologize to my fans, teammates and the Grizzlies organization for regrettably not doing the necessary research about what supplements I can put in my body.""
