UFC 168: Dennis Siver tests positive for human chorionic gonadotropin (hCG) following win over Manny Gamburyan

Ultimate Fighting Championship (UFC) featherweight Dennis Siver has tested positive for the banned substance human chorionic gonadotropin (hCG) following his unanimous decision win over Manny Gamburyan at the UFC 168 pay-per-view (PPV) event, which took place back on Dec. 28, 2013 in Las Vegas, Nevada.

MMA Fighting has the skinny direct from Nevada Athletic Chairman Francisco Aguilar:

"The Nevada Attorney General's office is preparing the appropriate complaint for the State of the Nevada," Aguilar said. He didn't reveal Siver's exact hCG level or what kind of punishment he might receive.

Most commonly known as a female fertility drug, hCG is typically used by steroid users in an effort to restart their testosterone production following steroid usage.

Siver first returned an "inconclusive result" when the original test results were released earlier this month (details). That prompted the commission to have the featherweight's "B sample" tested for further analysis and it returned positive for the banned substance, made famous by baseball's Manny Ramirez back in 2009.

Bad company.

Siyar Bahadurzada also needed to go back into the lab after his test result was inconclusive; however, the second time proved to be the charm, as "The Great's" extra sample returned negative. Gamburyan, as a result of Siver's fertility fail, may have his loss changed to a "No Contest," depending on the commission's ruling.

Stay tuned.
