What energy in the arena.  It looks like the UFC has unleashed a new promotional video and it has the fans pumped up. This is the first fight of the main card, being televised on pay-per-view.

Sobral begins the first round with a flurry and takes Lambert to the ground, even attempting a rear naked choke. But Lambert gets the fight back on its feet and drops Sobral to the ground with some nice punches and knees. Sobral looks hurt at the end of the first round. The crowd roars as the first round ends. The first round is too close to call.

In the second round, Lambert controls the fight on the ground, grounding and pounding before referee McCarthy stands the two fighters back up. But the fighters aren't up for long as Lambert devastates Sobral with a punch that knocks out Sobral and keeps him on the ground for a couple of minutes after the fight has ended.

Official result: Jason Lambert wins by KO at 3:36 of Second Round

Referee: Big John McCarthy

Celebrity watch: I went back into the Media workroom to get some food from the buffet before the main card began (UFC treats the press very nicely ...) but there wasn't any food left.  However, UFC President Dana White was back there, mingling and taking pictures with fans and other members of the press alike.  Also spotted along the way were middleweight champ Anderson Silva, who was engulfed by fans who wanted to take pictures with him, including one lady who had some skin signed (I'll leave it up to your imagination where the skin was.)  Also spotted was light heavyweight Keith Jardine.

Unknown referee mystery solved: The ref for the 1st and 3rd matches of the undercard was Mike Matheny. Thanks to the UFC for that information.
