Bellator officials have yet to confirm or deny the result.
Warren (12-4) faces a 90-day suspension after a post-fight test showed he barely missed the allowable cutoff for marijuana metabolites in his system, coming in at 53 ng/ml, or 3 ng/ml over the limit allowed by the Texas Combative Sports Program, which oversaw his fight on September 25 in Hidalgo.
This is the second time a positive marijuana test has impacted Warren’s athletic career. He was suspended by the U.S. Anti-Doping Agency for two years after a second positive test for the drug in 2007. Appealing his punishment, he told arbitrators he used the drug to combat depression and a sleep disorder.
