According to the Nevada State Athletic Commission, former Strikeforce champion Nick Diaz tested positive for marijuana metabolites following his controversial loss to Carlos Condit at this past weekend’s UFC 143 event.

This is Diaz’s second offense with the NSAC and he will ultimately have to appear before them to address the issue. Last time he tested positive for marijuana it was following his win over Takanori Gomi in 2007 at PRIDE 33. He was suspended for six months and the result of the bout was changed to a no-contest.

* DANA WHITE Comments On NICK DIAZ Failing Another Drug Test

According to Strikeforce CEO Scott Coker, a grudge match between Strikeforce Welterweight champion Nick Diaz and Jason “Mayhem” Miller is being planned and could be finalized in the near future. Coker told the New York Daily News:

“It’s something that we’re definitely looking at. You have to look at it from all different angles. Would it be a fun fight to promote? Sure. I think we should wait until the beginning of the year, and let’s have another conversation on that because with Miller and Diaz I just couldn’t imagine the extra security that I’d probably need to get to make that fight happen.”

We’ll keep an eye on this story and will post a followup when new details become available.
