The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) informed Michal Oleksiejczuk of a potential Anti-Doping Policy violation stemming from an in-competition sample collected in conjunction with his recent bout against Khalil Roundtree at UFC 219 in Las Vegas, Nevada on December 30, 2017.

USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Oleksiejczuk, as it relates to the UFC Anti-Doping Policy and future UFC participation. Because the Nevada Athletic Commission was the regulatory body overseeing the fight in Las Vegas and has licensing jurisdiction over Oleksiejczuk, USADA will work to ensure that the Nevada Athletic Commission has the necessary information to determine its proper judgment of Oleksiejczuk’s potential anti-doping violation. Additional information will be provided at the appropriate time as the process moves forward.
