UFC featherweight Dennis Siver tested positive for human chorionic gonadotropin (hCG) following a win over Manny Gamburyan at UFC 168 on Dec. 28 in Las Vegas.

The Nevada State Athletic Commission confirmed Siver's positive test to ESPN.com on Saturday.

NSAC chairman Francisco Aguilar said a complaint is currently being prepared by the Nevada Attorney General's office.

The substance hCG is linked to anabolic steroid use and/or weight cutting. The NSAC tested all 22 fighters at UFC 168 and all other tests came back negative.

Siver does have the right to an appeal.

However, he faces a likely fine and suspension based on the current result. His unanimous decision win over Gamburyan would also change to a no-contest.

Fighting out of Mannheim, Germany, Siver (22-9) is 3-1 since dropping to the UFC's featherweight division in 2012. Prior to that, he had fought the majority of his UFC career as a lightweight.
