Nick Diaz, former Strikeforce Welterweight Champion and UFC Welterweight/Middleweight fighter who was slapped with a five-year suspension from competing in mixed martial arts after a drug test at UFC 183, showed he tested posted for marijuana. However the Nevada State Athletic Commission (NSAC) will recheck their and possibly re-instate Diaz on January 12 according to MMA Fighting.
The decision is largely thanks to a petition signed by fight fans and the legal team of Campbell & Williams, who represent Diaz and have been challenging the ban. Diaz has had history of failed drug tests in Nevada in the past though, and will still be facing a $100,000 fine and an 18 month suspension from fighting. But it would it still be a lot better than his current status.
If re-instated, fight fans could see him back inside the ring at UFC 200 in July. The return of Diaz to the ring should be good for ratings or pay-per view buyouts. Nick, like his brother Nate, has long been fan-favorite with the aggressive fighting style and outspoken and verbally abusive demeanor.
