Abdul-Kerim Edilov has not had a very good 2016.

After signing with the UFC and agreeing to face Francimar Barroso last month at UFC Fight Night 81, an injury forced the 20-fight veteran out.

Now, Edilov (16-4) has failed a pre-fight drug test given to him by the USADA, according to a statement released by the UFC.

“USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full and fair legal process that is afforded to all athletes before any sanctions are imposed. Additional information will be provided at the appropriate time as the process moves forward.”

Edilov has earned 10 consecutive first round finishes, which likely caught the eye of UFC officials. Of his 16 career wins, 15 have been stoppages, including eight knockouts and another seven submission wins.

It remains to be seen if the fighter will ever get the opportunity to compete inside the Octagon now.
