UFC 143 drug test results return with one positive for 'Diaz vs Condit' event

Uh-oh.

With all the controversy surrounding the UFC 143: "Diaz vs. Condit" event, and most of it swirling around the Nick Diaz vs. Carlos Condit headlining bout, this just puts the cherry on top.

Nevada State Athletic Commission (NSAC) Executive Director Keith Kizer sent out an e-mail today confirming that one fighter who competed on the card returned a positive result on their drug test:

Thank you for the many email and phone calls. I am still waiting for all the steroid and drug test results to come back. We did have at least one positive test. I will send out an email later today on that matter.

Naturally, assumptions are going to be made and at this point, it's difficult to refute them. The Diaz camp had been lobbying for a rematch against Condit and apparently got their way, as UFC President Dana White all but confirmed the two were going to be set up for another date later this year.

Then, suddenly, everything changed course and Cesar Gracie, head of the Diaz band of rebels, changed his tune.

Seemingly out of nowhere, Gracie told multiple media outlets that the rematch would not be happening. He refused to go into specifics, though, and left us all to wonder just what the heck is going on.

But then Josh Gross straight out asked Gracie about the rumor floating around that Diaz had failed his drug test and his response was rather interesting, to say the least:

I asked Cesar Gracie yesterday re: rumor about an issue w/ Nick Diaz's drug test. His answer: "I have been told not to comment on anything."

And the plot thickens.

If it is indeed Diaz, who is an unabashed, proud medical marijuana card-carrying member -- who also tested positive for THC after his epic win over Takanori Gomi in Las Vegas back in Feb. 2007 -- it would be a colossal career disaster.

However, that's a big IF until official word comes from the NSAC -- for all we know if could be Carlos Condit or one of the other 19 other combatants who competed on the UFC 143 fight card.

To be clear, we cannot confirm at this time that Diaz failed his drug test, even if all signs are pointing in that direction. Kizer noted that he will notify everyone once all results are in and then -- and only then -- can speculation be laid to rest.

In the meantime, feel free to share your thoughts on all this madness, Maniacs.
