Unfair! UFC 166's Daniel Cormier to file formal complaint if Roy Nelson rocks Hillbilly beard in Houston

Ultimate Fighting Championship (UFC) heavyweight and The Ultimate Fighter (TUF) 10 winner Roy Nelson is the most dangerous mixed martial arts (MMA) fighter Strikeforce import Daniel Cormier has ever faced.

His words, not mine.

It would make perfect sense then, for "DC" to try to get any advantage he can on fight night, even if it means going after that bird's nest under "Big Country's" chin. In fact, Cormier plans to file a formal complaint with the Texas athletic commission prior to their UFC 166 co-main event on Oct. 19, 2013 in Houston, demanding that his opponent shaves his beard.

Nelson's response?

The portly power-puncher told UFC Tonight that if a beard is capable of providing an "unfair advantage," then Cormier "should have had a beard when he failed in the Olympics in 2008 and 2004."

Yeah, he went there.

If any of this sounds familiar, it's because it is. Back in July, Jorge Masvidal (unsuccessfully) lobbied The Washington State Athletic Commission to have UFC on FOX 8 opponent Michael Chiesa razor-up, because "Gamebred" did not want to be subjected to "Maverick's" rampant herpes.

Yes, really.

Whether or not Cormier moves forward with his plan to appeal the bristly Vandyke remains to be seen, as it could just be a way to get under Nelson's skin and disrupt his opponent's mentality prior to fight night. Then again, Nelson "is not a smart guy," according to UFC President Dana White, so he may show up in "The Lone Star State" unfazed.

Typical husband and wife stuff.
