No. 3 -- Donald Cerrone

It doesn't matter to Cerrone who he's fighting, so long as he's fighting. Cerrone has filled in on numerous occasions on very short notice (usually replacing Sam Stout) and had opponents fall out and be replaced, too. But no matter who's standing in front of him on fight night, he treats everyone exactly the same: rudely. "Cowboy" is always game.
