Alright, we're less than 30 minutes away from the beginning of the action. Or rather, 30 minutes away from "Optimus Bellum Domitor" and the unveiling of Mike Goldberg's Haimov watch of choice for the evening. Sounds like the prelims have been pretty exciting, so as usual please refrain from undercard spoilers in the comments.

And we're off!

Before the opening package, the UFC dedicates the show to Nelsen Bernardo, an in-house graphic designer for Zuffa who passed away in a car accident last week.

Demian Maia vs. Jason MacDonald

Maia enters to... Braveheart music? He's got Wandy in his corner. I see Clay Guida in the crowd, so hopefully we'll get some great shadowboxing later on in the evening. MacDonald's entrance music of choice is Metallica's cover of "Turn The Page."

Round 1 - Maia throwing left kicks low and high to start off. MacDonald clinches almost immediately and Maia pulls guard. Jason staying tight to the body as the Brazilian peppers him with shots. MacDonald leaves an arm exposed and Maia cinches up a VERY tight triangle. He pulls MacDonald's head down and Joe Rogan pronounces the bout over, but "The Athelete" won't tap. Now MacDonald stands and frees himself, quickly takes Maia's back and sinks in a rear naked choke! Maia frees himself and MacDonald works from the guard. MacDonald stands and lunges in, grabbing Maia's head and squeezing on a guillotine. Maia's cut near the left eye, now slips out of the guillotine and takes MacDonald's back. Now Maia takes the rear naked with :30 remaining! MacDonald rides it out and the round expires with the submission and body triangle still sunk in. BloodyElbow.com scores the round 10-9 for Demian Maia.

Round 2 - Maia catches MacDonald with a hard left hook to open the round, and MacDonald immediately shoots for a double and puts him against the fence. Now Jason against the fence with Maia throwing big knees, but not much connecting. Maia trips him to the ground, now in full guard raining down punches. Some hard elbows from Maia and MacDonald is bleeding from the nose. Maia smothering and neutralizing MacDonald's attempts at offense from the bottom with 2:00 left. Now Maia in full mount, throwing non-stop punches, alternating left and right as MacDonald simply covers up. These shots aren't landing flush but they're obviously frustrating the Canadian fighter. MacDonald finally escapes; Maia has isolated his left arm but can't do anything with it and it's MacDonald's turn on top again. BloodyElbow.com scores the round 10-9 for Demian Maia.

The crowd surprisingly cheers for a very technical match between rounds. MacDonald's corner tells him he needs to knock Maia out.

Round 3 - Maia tries for a guillotine as the round begins, but MacDonald trips him down and lands on top, popping his head out. Now MacDonald takes Maia's back again and tries for a neck crank/guillotine. Maia with another great escape and now the BJJ expert is back on top. MacDonald rolls and gives up his back, now he's taking shots that drive his head into the mat as Maia tries to snake his right hand under the neck. Both fighters look exhausted. MacDonald stops paying attention for a fraction of a second and Maia loops his right arm under and locks on an inescapable rear naked choke. MacDonald taps Maia's leg and Yves Lavigne steps in to stop it. Demian Maia def. Jason MacDonald via Submission (Rear Naked Choke) - R3, 2:44

Roger Huerta vs. Kenny Florian

Roger Huerta looks fired up as ever - he's doing wind sprints back and forth across the octagon. Looks like KenFlo borrowed Uma Thurman's tracksuit from Kill Bill. And don't look now, but "Big Dan" is our ref.

Round 1 - Huerta opens up with some sharp leg kicks. Florian tries to jump in with a knee, and eats a couple punches for his trouble. Takedown by Florian, now in Huerta's full mount. Huerta gives up his back and Kenny's got him flattened out against the cage, punishing the adopted Minnesotan with strikes. The fight gets back to its feet as Huerta stands and shakes Florian off. It's almost like it's nothing for Roger to give up his back, he gets out of that situation at least once every fight. Crisp strikes from Huerta that seem to faze his opponent, who drops down for a single-leg but is stuffed. Now the fighters clinch and Florian brings up a hard knee to Huerta's body. Huerta is pushing forward but missing a lot of punches due to some nice head movement from the Boston boy. Very close round, but I've got to give it to Kenny for taking the back. BloodyElbow.com scores the round 10-9 for Kenny Florian.

Round 2 - Huerta looks desperate for a takedown in the first minute, but is repeatedly stuffed as Florian backs into the cage. Goldberg notes "Kenny's avoidance is good." Kenny shoots but Huerta stuffs and is working for a standing kimura. Now they go to the ground and Florian takes top, then Huerta's back... but he's up too high and Roger escapes again. 2:00 left and they're back standing. Florian comes forward and sweeps Huerta's left leg. Roger hits ground but the Bostonian can't capitalize. Florian looking Machida-esque in his gameplan, peppering Huerta with shots whenever he comes forward. Huerta is in love with his Superman punch, which has been completely ineffective in this match thus far. I think he's thrown seven or eight. BloodyElbow.com scores the round 10-9 for Kenny Florian.

Round 3 - The two enthusiastically touch gloves as the round begins. Roger rushes in wildly and Kenny single-legs him clear across the cage. Back to the feet and Florian is landing stiff jabs at will that seem to simultaneously bewilder and piss off Huerta. Florian throws an elbow which narrowly misses Huerta, to which Kenny responds by pointing to Huerta's head. Maybe a little gamesmanship, as Huerta seems to check his forehead for a cut. Nasty front kick from Kenny catches Huerta right beneath the jaw. Now Huerta eats some jabs and attempts to unload, but Florian's dancing out of the way of almost everything. Huerta puts everything into a left kick to Florian's midsection, but overexerts himself and falls to the ground. Florian tries for a guillotine with about :20 remaining, then shoots some knees up into Huerta's grill as time runs out. BloodyElbow.com scores the round 10-9 for Kenny Florian.

BloodyElbow.com scores the bout 30-27 for Kenny Florian.

After the fight, Florian says he "really wanted a dominant performance over Roger" and dedicates the win to fellow Bostonian Jorge Rivera, whose eldest daughter passed away this week.

Rob Emerson vs. Manvel Gamburyan

I'm suddenly moved to root for Rob Emerson, who enters to the Diplo remix of M.I.A.'s "Paper Planes." Very nice.

Round 1 - Gamburyan comes out swinging with a pair of overhand rights. As he throws the second one, Emerson jacks his jaw with a right of his own that sends the Armenian to the canvas. Manny struggles to get back to his feet, but Emerson follows him down and connects with a left hook that puts Gamburyan out cold. He wakes up two seconds later, but Yves Lavigne has already (correctly) called this one off.

Brock Lesnar vs. Heath Herring

Lesnar is sponsored by Jack Link's beef jerky and enters to "Shout At The Devil." Oh man, did I seriously pick Brock Lesnar? "Big Dan" just poked Herring in the left eye during the staredown. WTF?

Round 1 - Lesnar comes out with a ridiculous flying knee that misses, then composes himself and sends Herring tumbling to the canvas with a right. Lesnar jumps on the injured "Crazy Horse" and squeezes Herring's head underneath his massive arm. Herring still in the guillotine, back to the cage - it doesn't look serious but some blood is running down the Texan's face now. Herring shoves out. Lesnar shoots and takes Herring down with ease. Looks like Lesnar is going for some ride time as he maintains Herring's back. Brock is landing tons of powerful shots from the back, now Herring looking up at Miragliotta and "Big Dan" warns Lesnar about hitting to the back of the head.

The crowd chants and some of that WWE experience comes out as Brock showboats, raising his head momentarily to nod along with the crowd. BloodyElbow.com scores the round 10-8 for Brock Lesnar.

Round 2 - Another shot from Lesnar to open the round, backing Herring into the fence, but Heath doesn't go down this time. Second attempt does it. Lesnar in side control. Big elbows connecting to the face of Herring, who tries to stand and gives up his back.

Heath shoots some good knees up the middle as they tie up against the fence, but Lesnar scores another takedown as the round expires. BloodyElbow.com scores the round 10-9 for Brock Lesnar.

Herring scrambles out but Lesnar maintains side control; he's picking up and rolling Heath at will. Herring goes to stand, but Lesnar's arms are wrapped around his waist. Sensing the impending suplex, Heath wisely sits back down. Herring continues to scramble, but Lesnar winds up in side control or full mount each time. The match ends and Lesnar looks ecstatic, jumping up and down, pointing at Herring with his mouth agape. Not sure if he meant it as an insult, but Herring walks over to embrace and congratulate him regardless. BloodyElbow.com scores the round 10-9 for Brock Lesnar.

Spinning back-kick to the midsection lands for Georges.
