UFC 137 - Penn vs. Diaz predictions

The Georges St. Pierre thrashing of Nick Diaz has been postponed due to injury.

Instead, we'll see B.J. Penn, 32 years young, crack open his best attempt at whoop-ass this Saturday night against Diaz, four years his junior and fighting out of California. It's not that we're unexcited, but GSP's withdrawal after a knee injury does have us mustering little more than a yawn for the new main event.

Nevertheless, we're sure to be in for a fight. Diaz (25-7) has youth and a 10-fight win streak on his side. Penn (16-7) has, well, confidence to say the least.

Expect this fight to favor Diaz, if not for momentum going into the fight. We're not counting out B.J. Penn, but Diaz has some making up to do after a few recent PR foibles. We predict a second-round flash KO from Diaz.

Also of note for UFC 137, Mirko Cro Cop is back to face Roy Nelson. We're hopelessly predicting Filipovic to resurrect PRIDE form and lay "Big Country" a highlight headkick. Then again, we've been hoping for the old Cro Cop to return since he first joined the UFC. Realistic prediction: Nelson by TKO, late second round.
