Light heavyweight James Irvin has tested positive for Methadone and Oxymorphone, following his first round technical knockout loss to Anderson Silva at UFC Fight Night 14 on July 19, according to the Nevada State Athletic Commission (NSAC).
Methadone and Oxymorphone are often used to treat chronic pain.
The "Sandman" has 20 days to respond and request a formal hearing to dispute the finding. If the ruling is upheld after the hearing he faces a possible fine and suspension.
All of the other fighters tested on the card came back clean.
Stay tuned for more on this developing story.
Note that we passed along a story earlier today that the 11 fighters tested for the Spike TV special event tested clean for steroids and drugs of abuse. That was inaccurate ... those tests were just for steroids.
