The UFC released the following statement on its website.

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Zubaira Tukhugov of a potential Anti-Doping violation stemming from out-of-competition sample collections made on September 7, 2016 and October 29, 2016. USADA has provisionally suspended Tukhugov based on the potential anti-doping violation. The UFC is removing Tukhugov from his scheduled bout against Tiago Trator on December 9 in Albany, New York, and is in the process of attempting to locate a replacement.

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 fair legal review process that is afforded to all athletes before any sanctions are imposed. Consistent with all previous potential anti-doping violations, additional information or UFC statements will be provided at the appropriate time as the process moves forward.

Tukhugov’s last fight was a split-decision loss to Renato Carneiro at UFC 198 in May.

The process continues.
