Daniel Cormier is on a mission to trim Roy Nelson‘s hair, and UFC President Dana White is ready to hand him the shears.

“I don’t blame (Cormier),” White told a small group of reporters on Monday in Los Angeles. “I wouldn’t want that nasty thing rubbing on my face, either, during the fight.”

This past week, according to a report on FOX Sports 1’s “UFC Tonight,” Cormier (12-0 MMA, 1-0 UFC) said he would file a complaint with the Texas Department of Licensing and Regulation to force Nelson (19-8 MMA, 6-4 UFC) to clean up his signature beard.

The Texas commission oversees the pair’s bout at UFC 166, which takes place Oct. 19 at Houston’s Toyota Center. The main card, including Cormier-Nelson, airs on pay-per-view following prelims on FOX Sports 1 and Facebook.

Cormier said the facial hair gives Nelson an unfair advantage in the fight, which could be Cormier’s last before a long-discussed potential drop to the light heavyweight division. The winner of the Strikeforce heavyweight grand prix, Cormier defeated former champ Frank Mir in his octagon debut, but has targeted a bout with rival Jon Jones for the near future.

“I’m going to request that there’s a rubber band in it and that it comes straight down,” Cormier said of Nelson’s beard. “Also, I’m going to ask that they put his hair in two parts off to the side. Part it down the middle, part it on the sides. I don’t want it all in my face.”

White agrees, if only in spirit. The UFC executive has never been a fan of Nelson’s shaggy appearance, and once told the fighter he should tidy up so as to attract more attention from sponsors.

Nelson, who recently signed a nine-bout contract with the promotion, didn’t exactly take the advice to heart. The 37-year-old fighter has made his mullet and beard as much of a signature as his round belly, which White isn’t a fan of, either.

“I hate that whole, ‘You can grow a beard down to here and still fight in MMA,'” White said. “It’s not even allowed in boxing, and they don’t go to the ground and have side control.

“Who would want that thing laying on their face? Seriously? That long, nasty, ratty looking thing in your mouth, rubbing on your face … I mean, it’s ridiculous. They shouldn’t be allowed to have beards that big. If you want a beard, trim that thing down and make it look normal. Disgusting.”

It’s unclear if Cormier and White’s fight is winnable. TDLR statutes don’t specifically address beards or long hair, but rather say contestants “must be clean and present a tidy appearance.”

A rep for the TDLR on Tuesday told MMAjunkie.com that Cormier has yet to file a complaint on the matter.

“It may be one of those things that have to be put in there in the future,” said Randy Nesbitt, project coordinator with the TDLR, when asked what the commission’s standards are on facial and body hair.
