Nick Diaz appeared on Sportsnet Fan 590 radio's "Tim and Sid" and made a startling, and entirely unsubstantiated charge against UFC welterweight champion Georges St-Pierre.
Diaz earlier defended himself against accusation that he was not "playing the game" as far as media responsibilities.
"They do everything they can, in their power, to create these problems for me," said Diaz. "I'm not crazy, I'm not delusional, I'm not playing the victim card."
Then, at the 12:42 mark, Diaz was asked about references he made at the pre-fight press conference to "big guys on steroids holding me down." With little prodding, Diaz went after his opponent Saturday night.
"I believe that he's on plenty of steroids," said Diaz. "And I don't think they test around here either and I doubt I'll be tested here as well. I don't care what they're saying or marketing to the media, I don't think either of us are going to be tested and if so, he's probably got a bottle of piss in his pocket. I doubt they're standing over him making sure he's not on steroids."
The interviewers pounced, working UFC president Dana White's name into a leading question; the media unsavvy Diaz bit.
"So you're suggesting that the face of the franchise is on steroids" Diaz was asked. "And that Dana White would be complicit with that?"
"Sure, why not" replied Diaz. "Lance Armstrong is on steroids. And it was really a ridiculous thing that he was on steroids. You know... that as far as he was concerned."
The interviewers then pressed the issue.
"Nick, this is strong stuff," Diaz was asked. "Can you guarantee me you will be clean after the fight? These are strong allegations man."
Diaz' reply was vintage Nick Diaz.
"Hell no I'm not guaranteeing anything," he said. "I think I tested, like, for metabolites or a nanogram or something, so I just did a little more than I did last time. I'm sorry if I don't pass the test, but I think it should work out. I've passed plenty of them before. Unless they just weren't testing me? I wonder how much they test people around here?"
Athletic Commissions routinely test several fighters on any card, and as a rule always test both the champion and the challenger. GSP has fought in eleven straight title bouts, and has never tested positive for anything.
