Former Bellator bantamweight and featherweight champion Joe Warren tested positive for marijuana following his latest victory at Bellator 143.

Warren defeated L.C. Davis by unanimous decision at the event on September 25th in Texas, but tested positive for the drug post-fight and as a result he’ll now have to serve a 90 day suspension.

The 38 year-old was reported to have a marijuana metabolities reading of 53 ng/ml, just 3 ng/ml over the limit in Texas. If he had been fighting in Nevada, Warren wouldn’t have been suspended as they recently raised their limit to 150 ng /ml.

Prior to his MMA career Warren tested positive twice for marijuana as a wrestler, with the second instance resulting in a lengthy ban that prevented him from competing at the 2008 Olympics.

Recently, Warren publicly revealed that he holds a license to use medical marijuana in two different states.

He also spoke out on Nick Diaz’s five year suspension for a third marijuana test, telling MMAjunkie, “That’s terrible for him. It’s a law, though. I’m the first one to say, you break a law, you’ve got to deal with it.”

Warren lost his Bellator bantamweight title to Marcos Galvao earlier this year, but that’s his only loss in his last seven fights and his latest victory over Davis has put him right back into the title hunt.
