Konstantin Erokhin is having a rough few months.

The Russian heavyweight's latest fight was a highly criticized, listless unanimous decision loss to Gabriel Gonzaga at The Ultimate Fighter 22 Finale on Dec. 11 in Las Vegas. And late last month, Erokhin was removed from the UFC roster.

Now, Erokhin's drug test from the TUF Finale has come back positive. Erokhin popped for the anabolic steroid drostanolone in a pre-fight, in-competition test, according to documents obtained by MMA Fighting through a public records request with the Nevada Athletic Commission.

Erokhin failed a test sent to Quest Diagnostics administered by the NAC, not a test administered by USADA. He will face a suspension and fine from the NAC in an upcoming hearing.

Erokhin (9-3) went 0-2 in the UFC, also falling to Viktor Pesta in January 2015. He came into the UFC winning nine in a row -- all but one via knockout -- on the European circuit. Erokhin, 34, has wins over veterans like Brett Rogers and Dave Huckaba.

NAC executive director Bob Bennett said Wednesday he was unsure when Erokhin would be scheduled for a disciplinary hearing.

No other fighters on the TUF 22 card came back positive. Frankie Edgar defeated Chad Mendes in the main event. The testing information also encompassed samples taken by USADA, which runs the UFC's anti-doping program.

The tests done regarding the adjacent cards, UFC 194 and UFC Fight Night: VanZant vs. Namajunas, all came back negative, including headliners Conor McGregor, Jose Aldo, Chris Weidman and Luke Rockhold. See the spreadsheet for UFC 194, provided by the NAC, below:
