UFC's Josh Barnett flagged by USADA for potential violation

Josh Barnett is the latest UFC fighter to be flagged for a potential drug test violation.

Barnett, 39, who doubles as co-host of New Japan World Pro Wrestling on AXS, was reported today to have had an issue with a December 9th out-of-competition test issued by USADA.

Barnett had tested positive for banned substances previously in 2001 in Nevada, after a win over Bobby Hoffman, in 2002 in Nevada, after he captured the UFC heavyweight title from Randy Couture, and in 2009 in California, prior to a fight with Fedor Emelianenko.

He is coming off a win over Andrei Arlovski on September 3rd in Hamburg, Germany and was not signed to a new fight.

Barnett was also a pro wrestling star in Japan, and became a protege of Billy Robinson. He headlined the January 4th, 2003, show at the Tokyo Dome, losing in the main event for the IWGP title against Yuji Nagata.
