UFC fighter James Irwin threw a loaded urine after a recent Nevada fight...only not loaded for steroids (Bleacher Report ) but loaded with narcotics.
It also had to do with another flight during which he (Irvin) was on the illegal drug oxymorphone (a narcotic painkiller for extreme pain). James also tested positive for methadone (a synthetic form of heroin given to addicts to relieve withdrawing symptoms).
The report mentions 'recovery'. Masking pain isn't a good idea for recovery. Rest would be a better idea, to give the bones and tissues time to heal. Time to heal appears not to be ideal for the pocketbook of the owners, and athletes these days. But opioid drugs aren't a great option, either, especially when alertness might be a bit important in an MMA fight. (oxymorphone is Numorphan)
Eleven of the 22 fighters who competed on the card were tested at the event. Anderson Silva, James Irvin, Hermes Franca, Cain Velasquez, Brandon Vera, CB Dollaway, Tim Credeur, Frankie Edgar, Shannon Gugerty, and Nate Loughran all were tested for steroids, drugs of abuse, and stimulants.
Irvin was the only competitor who tested positive for a banned substance.
He has been temporarily suspended pending a disciplinary hearing with the NSAC. The regulatory body could vote to revoke his licensure for a yet-to-be determined length of time and/or fine him for the alleged infractions. A date for the hearing has not been set.
Irvin had broken his foot in May while preparing for a match against Rashad Evans. It is probable that he was using these drugs to speed his recovery for the Silva fight. Irvin's manager said that he was unaware of the allegations. Neither Dana White nor Irvin himself has commented on the issue yet.
