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."
