The Ultimate Fighting Championship on Monday revealed that middleweight standout Chris Leben tested positive for Oxycodone and Oxymorphone following his loss to Mark Munoz on Nov. 5 in the UFC 138 main event in Birmingham, England.
There is no athletic commission to oversee mixed martial arts events in England, so the promotion polices itself under the supervision of former executive director of the Nevada State Athletic Commission Marc Ratner, who is now UFC Vice President of Regulatory Affairs.
As a result of the positive test, the UFC suspended Leben for one year.
“I like Chris and I want him to do well, but based on his actions, he’s been suspended for one year,” UFC president Dana White said. “If he needs professional help, we are going to be there for him. We want to see him succeed not only in the Octagon, but in his personal life.”
“I would like to make it known that I fully accept this suspension and apologize for embarrassing the UFC, my friends and family, and the sport of mixed martial arts,” Leben said. “I’m learning that I’m my own worst enemy sometimes. I can’t succeed in the Octagon or in life behaving this way. I’ve got to make some real changes over the next year and I’m going to focus on getting my life and career back on track. Again, I’m sorry to the UFC and fans that’ve supported me since my days on The Ultimate Fighter.”
Leben has been in and out of trouble over the course of his career, arrested for an alleged DUI, and has tested positive for Stanozolol, a steroid.
UFC officials noted that the remaining 19 fighters on the UFC 138 fight card all passed their post-fight drug tests.
UPDATE: UFC officials confirmed to MMAWeekly.com on Tuesday that Leben will face the suspension, but was not fined for his infraction.
