This past weekend was UFC 131, and on Friday a lot of the sexy fighters striped down to their undies and weighed-in. Surprisingly most of the fighters wore boxer briefs, and of course most of them were patterned.
The MMA fighters featured in the gallery are Darren Elkins, Dustin Poirier(L), James Head, Nick Ring, Mike Massenzio, Chris Weidman, Sam Stout(R), Donald Cerrone and Kenny Florian. I also added a video highlight after the jump!
