Following Nick Diaz’s decision loss to Anderson Silva at UFC 183, and the news that he tested positive for marijuana metabolites after the event, the renowned fighter has hinted his fighting career might be over.

The following post appeared on Diaz’s Instagram account recently, and included the hashtag “dunfighting”. Could that mean he’s not planning to compete again?

Diaz has walked away from fighting in the past, and has been extremely critical of how fights are scored throughout his career. In addition, since Diaz has tested positive for marijuana use in Nevada before, the fighter could be facing a lengthy suspension.
