Ouch.

Roy Nelson was bleeding like a stuck pig in his heavyweight fight against Fabricio Werdum last Saturday night (Feb. 4, 2012) in the co-main event of UFC 143: "Diac vs. Condit" from the Mandalay Bay Events Center in Las Vegas, Nevada.

Not hard to see why.

Nelson was battered across three rounds by the much larger "Vai Cavalo," eating several knees in the clinch and taking an inordinate amount of abuse en route to a unanimous decision loss.

"Big Country" summarizes:

"Here is the cut from me head butting Werdum's knee in the 1st. My face is fine, forehead is a little sore.gym monday, pissed and it's not the happy Roy, stitches total I want to say about 16-20 two cuts. As [an] entertainer I always must put on show to give it drama and suspense, and maybe a little horror (blood)."

The defeat to Werdum drops Nelson to 2-3 over his last five and 16-7 overall. Catch a complete recap of their fight plus all the action from UFC 143 right here.
