UFC 137 weigh in results LIVE from Las Vegas for 'Penn vs Diaz'

The official weigh in event for UFC 137: "Penn vs. Diaz" took place today (Oct. 28, 2011) LIVE from the Mandalay Bay Events Center in Las Vegas, Nevada.

And the 209 was definitely in the house when Nick Diaz put his head up against B.J. Penn's to ignite a nice little pull apart during the staredown. Get hyped, ladies and sirs.

Everyone made weight without incident save for Tyson Griffin, who came in a whopping three pounds over the 145-pound limit and has one hour to drop the excess baggage. We'll keep you updated on that situation.

Everyone else was good to roll.

UFC 137 will feature former welterweight champion B.J. Penn taking on ex-Strikeforce 170-pound titleholder Nick Diaz. In the co-main event, fast-rising heavyweight prospect Matt Mitrione challenges the hard-hitting Cheick Kongo.
