UFC fighter Liz Carmouche is campaigning to be the first openly gay athlete endorsed by Nike. 

We previously reported that Nike is actively seeking an openly gay athlete in a major pro sport to throw their support ($$$) behind. 

Carmouche took her campaign to Twitter today. More after the jump! 

We're not sure why he's chiming in anyway, since he won't ever be fighting Fallon Fox, but UFC fighter Matt Mitrione made an ass of himself on Monday when he went on a vitriolic rant against transgender female fighter Fallon Fox. 

During an appearance on The MMA Hour, Mitrione called Fallon Fox a "lying, sick, sociopathic, disgusting freak."

Sadly it doesn't end there. See what else Mitrione had to say after the jump.

Ahead of the UFC's first openly gay fighter's inaugural bash (no pun intended), UFC President Dana White hopes to clear the air about his homophobic reputation. What does White have to say to MMA Fighting about singing a different tune these days as he embraces the sports first gay fighter, Liz Carmouche?

The UFC has been slowly moving toward an inclusive environment in the past year, with a gay-for-pay porn actor competing on its reality show and President Dana white giving his anti-gay reputation a makeover. This week, however, the UFC has finally marked a bold step forward toward full LGBT-friendliness by signing its first ever openly gay fighter. 

Ultimate Fighting Championship President Dana White has been hounded by accusations of homophobia for years--and not without reason. White famously recorded a video blog back in 2009 targeting reporter Loretta Hunt with both anti-gay slurs and misogynistic vitriol.

He didn't help his case during "speedo-gate" when he had a bit of a freakout when one of his fighters performed in a speedo (a big "no no" in the macho UFC world). 

Still, White believes he's been misrepresented and even went so far as to encourage gay UFC fighters to come out back in Oct. 2011.

He addresses his perceived homophobia in a new interview where he's asked to reveal his biggest regret. We'd love to get your take on his answer.

The Marine Corps will be presented with 5,000 signatures from folks asking it to end its relationship with the UFC over the fighting championship's ongoing cultivation of homophobia. Details follow. 

Dakota Cochrane, a talented MMA fighter who has been cast in the new season of UFC's The Ultimate Fighter, has come clean about his past career in gay porn.

A washed-up UFC fighter, who has spent countless hours in the embrace of muscular, sweaty men, has made headlines today for refusing to train with gay fighters.

Dana White, president of the Ultimate Fighting Championship, has lost his mind after seasoned fighter Dennis Hallman donned Speedo-type trunks during a recent match. Follow the jump for the full brief.

UFC fighter and A-Team actor Rampage Jackson proves that he barely knows more english than "fag" and "tiny penis" in this clip of the suspiciously hyper-homophobic d-bag. Follow the jump to watch Rampage "teach Japanese people English," which includes nothing more than "I am a fag" and "I have a tiny penis." Charming.
