Not too shabby.

"Leben vs. Munoz," featured long-time mixed martial arts veteran Chris Leben fading after just two rounds of pressure from middleweight counterpart Mark Munoz, who put his best foot forward while making a case for a 185-pound title shot against reigning division deity, Anderson Silva.
