[Not really racist!]

I'm still curious why he fail-pass-failed... unless it was a false negative
So he actually wasn't cycling off at all?

According to the commission its a stimulant, so they can release it for grounds of disciplinary action? Not sure

Spoiler!

I recall Forrest Griffin getting popped for Xanax when he fought Silva and it was released to the public as well. I was always under the impression that you could get a TUE for prescribed psych medications granted you declared it to the commission before the fight with an ample amount of time.
