I don't have any links, but was reading about it on another forum. From what I was reading, it looks like he is claiming it was something from a supplement he was taking....same song and dance explanation. That's all I know though.
I read the same thing on MMA Fighting. He's lucky the test and fight were before the new rules were implemented! He's only getting a one year suspension...The new rules call for a two year suspension for 1st time offenders!!
