Nate Diaz says Dana White and UFC are 'full of s--t,' insists he didn't turn down Khabib Nurmagomedov fight

This is starting to get ugly.

Ultimate Fighting Championship (UFC) President Dana White recently told the mixed martial arts (MMA) community that Khabib Nurmagomedov would not be fighting Nate Diaz at one of the promotion's upcoming events, because Diaz "turned the fight down."

Read those comments here.

Turns out Dana and the UFC are "full of shit," according to the outspoken Stockton slugger, who took to his Twitter account to let the world know he never turned down a fight against "The Eagle," not long after he initially tweeted, "F U PAY ME."

See for yourself.

A gutsy move, considering how much blood is already on the chopping block.

Diaz is no stranger to social media head games, recently claiming he had no intention of fighting Gray Maynard at The Ultimate Fighter (TUF) 18 Finale because he was already committed to his high school reunion. Diaz did show up, but once again found himself in the headlines for his paltry purse.

See the surprising numbers here.

Despite calling out everyone from B.J. Penn (really) to Diaz himself, Nurmagomedov is still without an opponent, since a rumored fight against Gilbert Melendez -- a teammate of Diaz -- failed to materialize for the UFC 170 pay-per-view (PPV) event next month in Las Vegas, Nevada.

Sounds like Joe Silva has his work cut out for him.
