Spike TV's "UFC Prelims" special for UFC 137: "Penn vs. Diaz" on Oct. 29, 2011, averaged 1.1 million viewers, up from one million viewers for UFC 136 on Oct. 8 but down big from the 1.6 million it scored for the UFC 135: "Jones vs. Rampage" undercard offering back on Sept. 24.

The two fight broadcast from the Mandalay Bay Events Center in Las Vegas, Nevada, featured former WEC wrecking machine Donald Cerrone doing the damn thing by destroying another top lightweight in Dennis Siver.

Another WEC veteran represented in the form of Bart Palaszewski knocking out longtime Octagon worker Tyson Griffin inside the very first round.

"UFC Prelims" for Oct. 29 pulled in a 0.8 household rating, including a 0.89 in males 18-49 and a 0.85 in males 18-34.

UFC 137 featured the Octagon return of Nick Diaz, who emphatically made his case for the next welterweight title shot by battering and busting up B.J. Penn like never before en route to a three-round unanimous decision victory.

Wish granted. Georges St. Pierre vs. Nick Diaz over the Super Bowl weekend.

The rest of the card was, unfortunately, rather forgettable. Cheick Kongo cracked and crawled his way to a decision win over Matt Mitrione while Roy Nelson earned a third round technical knockout in Mirko Filipovic's final fight as a professional mixed martial artist.

Goodbye, "Cro Cop."
