http://www.ufc.com/news/UFC-Statement-on-josh-barnett-122716?id= 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. Barnett was not currently booked. Given that this is his fourth offence he will likely be given a lengthy if not lifetime ban.
He's not a great commentator or in ring performer but does seem to be a decent trainer. Shayna Baszler is doing well in NXT.
