Nate Diaz rules himself out of UFC 244 main event

Jorge Masvidal and Nate Diaz - UFC 244

Nate Diaz dropped a huge bomb on Thursday regarding his highly anticipated matchup with Jorge Masvidal UFC 244. 

Diaz stated that he was out of his headlining fight with Masvidal. The fight hasn't yet been officially ruled out by the UFC just yet. If this happens, this is definitely going to derail one of the biggest non-title fights in UFC history. 

The Stockton native tweeted that a drug test had shown "elevated levels," adding that he wouldn't make it to New York City for the Masvidal bout.

A lot of money has been put into this fight to officially happen. UFC president Dana White confirmed the promotion had even spent $50,000 to create a fictional "Baddest [expletive] on the Planet" title belt for the winner.

Diaz accuses USADA of alleged faking of drug test

"I’m not gonna make it out to NYC for fight week next week because they say I tested with elevated levels that they say might be from some tainted supplements,” Diaz wrote on Thursday.

 “I call false on that cause I only take Whole Food or natural food supplements. I don’t even eat meat," Diaz explains. “So until UFC, USADA or whoever is f---ing with me fixes it, I won’t be competing," he added.

Reports indicate however that the fight has not yet been ruled out. Neither the UFC nor any Anti-Doping Agency has provisionally suspended or otherwise call off the bout.

"UFC and USADA are gathering information and will issue a statement as soon as possible," USADA spokesperson Adam Woullard said.

What really happened?

Unidentified sources report that Diaz tested positive for trace amounts of a prohibited selective androgen receptor module (SARM). Diaz adamantly denied knowingly taking any banned drugs. The substance for which he said he was found to have "elevated levels was not identified.

A case like this, if proven true can possibly still make Diaz eligible to fight. UFC fighter Neil Magny had the same situation in the past but was still cleared to fight after trace amounts were found were believed to be ingested via a tainted supplement.

Diaz has been known to make exaggerated comments in the past. If this is the case, the fight might still happen.

"I don't give a f--- about some money over my dignity and my legacy," Diaz wrote. "I'm not playing along with this bulls---. I'm not staying quiet and figuring it out after the fight. That's cheating."
