Saturday night's Ultimate Fighter 7 Finale was unexpectedly pared from 11 down to 10 bouts at the last minute when
The fight was scrapped by the Nevada State Athletic Commission when traces of the prescription drug Adderall were found in a pre-fight drug test administered to Credeur according to the Ultimate Fighting Championship.
Credeur informed that commission before Friday's weigh-ins that he had been taking the drug up until about five days ago. He was voluntarily subjected to a drug test following the weigh-ins and traces of the drug appeared in his system.
"Unfortunately, the drug was still in his system and he's still positive, so he was unable to get cleared to fight," said
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.
According to drugs.com, "Adderall is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
"Adderall is used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD)."
