Saturday night’s preliminary bout between middleweights Tim Credeur and Cale Yarbrough at The Palms in Las Vegas was cancelled by the Nevada State Athletic Commission after traces of the prescription drug Adderall were found in a pre-fight drug test administered to Credeur.
Credeur, a member of The Ultimate Fighter: Team Rampage vs Team Forrest cast, informed the NSAC before Friday’s weigh-ins that he had been taking the medication up until five days ago. After the weigh-in, Credeur was sent to a Las Vegas lab for a follow-up test but when the results of the test came back Saturday morning, he still showed traces of the drug.
“Unfortunately, the drug was still in his system and he’s still positive, so he was unable to get cleared to fight,” said Keith Kizer, Executive Director of the Nevada State Athletic Commission. “It should be out of his system in a few days and hopefully they’ll find another fight for him.”
According to Kizer, Adderall “acts as a cardio-vascular restrictor and that’s the main reason it’s banned because it can cause athletes to have a cardiac episode with the stress they’re under when they’re in an athletic competition. Secondly, it can have a performance-enhancing effect as well.”
There will be no disciplinary action taken towards Credeur by the NSAC. “We found out about it beforehand, and he was very honest with us about it yesterday,” said Kizer.
