It's been a rough couple of days for arms (just ask Professor X).

Ultimate Fighting Championship (UFC) bantamweight butt-kicker Raphael Assuncao defeated Mike Easton in their UFC on FOX 5 "Prelims" contest held last Saturday night (Dec. 8, 2012) at the KeyArena in Seattle, Washington.

And he did it with a broken arm.

The Brazilian took to his official Facebook page following the fight to share a photo of his X-Ray. The busted bone came in the first round of his battle against the 135-pound "Hulk," which he initially believed to be a muscle spasm.

"Broke my arm in the first round! Thought it was a muscle spasm at first but was broke...no excuse lets keep the improvements + recovery on."

I guess the "excuse" he's referring to is remaining on the injured reserves until he gets better. The "Emerald City" win was his third straight and pushed his record to 19-4 overall. Easton falls to 13-2 in defeat.
