Middleweight MMA fighter Chael Sonnen reportedly failed a drug test following his loss to Anderson Silva at UFC 117.
According to Sherdog.com, Sonnen was notified of his positive test by the California State Athletic Commission over the weekend. Although it's not known specifically what the 33-year-old Oregonian tested positive for, it's believed to be a performance-enhancing drug, not "drugs of abuse."
"(Sonnen) received his notice yesterday," California State Athletic Commission Executive Officer George Dodd told Sherdog.com.
A report on SI.com indicated the failed test was due to abnormally high levels of testosterone.
Sonnen has 30 days to appeal the result, which carries an automatic $2,500 fine and year-long suspension. If he does appeal, it would be heard at the next CSAC commission meeting on Dec. 2.
A suspension would end the possibility of a lucrative rematch with Silva in early 2011. The rematch was reportedly scheduled for Feb. 6 in Las Vegas.
Sonnen, one of the most outspoken fighters in the UFC stable, lost to Silva when he tapped out in the fifth round of their championship fight Aug. 7 in Oakland, Calif. He dominated Silva, the reigning middleweight champ who was once thought to be virtually unbeatable, for most of the fight before submitting to a triangle armbar at 3:10 of the final round.
Known for his trash-talking as much for his fighting ability, Sonnen once suggested that the reason cyclist Lance Armstrong was stricken with testicular cancer was because he used illegal drugs. Armstrong, a seven-time Tour de France winner, has never tested positive for PEDs.
