Russian UFC heavyweight Ruslan Magomedov is the latest fighter on the roster to have been flagged by USADA over a potential anti-doping violation.

The UFC confirmed the news on their official website, noting that the 29 year-old had been singled out for potentially having used a banned substance following an out-of-competition test on September 17th.

That’s disappointing news as Magomedov has been one of just a select few up and coming heavyweights who has been able to add new life to the aging division in recent times, having notched up wins over Viktor Peska, Josh Copeland and Shawn Jordan so far in the UFC, to take his overall pro-record to 14-1.

Magomedov had been slated to face Stefan Struve next month, but pulled out of the fight earlier this month due to an injury.

Read the UFC’s full statement regarding the matter below.

“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 review 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.”
