The former UFC heavyweight champion failed an out-of-competition drug test stemming from a Dec. 9 screening, the UFC announced Tuesday. Barnett has been flagged by USADA and is facing a UFC anti-doping violation.
The potential positive marks the third time Barnett has run afoul of anti-doping rules while under the UFC banner, and his fourth issue while fighting for a major MMA promotion.
UFC official response
The UFC organization was formally notified today that the U.S. Anti-Doping Agency (USADA) has informed Josh Barnett of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection on December 9, 2016.
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.
