One of MMA’s biggest names returns to the cage today for a historic UFC 184 in Los Angeles tonight.

Historic, and not only because UFC Women’s Bantamweight Champion Ronda Rousey will defend against what she calls her greatest challenger yet in Cat Zingano in the main event. But also, because for the first time, a UFC card will feature a women’s bout as a co-main event as well, as former boxing champion Holly Holm continues her transition into MMA in a bout against Raquel Pennington.

We’ll have a play-by-play account of the action beginning in about an hour, at 8 pm ET/5 pm PT. Please join us — and remember to hit refresh often for the latest update!

Preliminary Card (to air on UFC Fight Pass)

Featherweights: Masio Fullen defeated Alexander Torres by split decision (29-28, 28-29, 29-28)

Lightweights: Valmir Lazaro defeated James Krause by split decision (29-28, 28-29, 29-28)

Preliminary Card (to be broadcast on FOX Sports 1)

Heavyweights: Derrick Lewis vs. Ruan Potts

Big boys start up my play-by-play coverage. Potts is a pioneer in his native South Africa who has lost his only (two) Octagon appearances. The American Lewis is 2-1 and known to be a brawler, and a -600 favorite.

Round One: Some ineffective standup to begin, as Potts mostly circles away from the brawler. Potts initiates a clinch, Lewis briefly whips him to the mat. Back up, Potts takes a low knee and the action is halted. Potts rolls back for a kneebar and nearly gets it. They scramble and Potts takes top. Lewis in half guard. Lewis reverses as Potts looks momentarily lost (?) and lands some heavy ground-and-pound.  I hated this round. 10-10.

Round Two: Ugly standup, ugly attempt at a lateral drop. One guy (Potts) crumbles and the other uses hammer fists. This fight is just a nightmare and really shouldn’t be happening at this level. Potts getting beat up and narrowly escapes a sloppy arm triangle. More punches and the ref finally steps in.

Derrick Lewis defeated Ruan Potts by TKO (punches) at 3:18 of round two.

Ugh. Let’s move on, shall we…

Welterweights: Dhiego Lima vs. Tim Means

Lima, whose brother Douglas is enjoying a good MMA career at Bellator, was a TUF finalist from Team Edgar. Means is on his second UFC run — he went 2-2 from 2012-2013, and has gone 2-1 with ZUFFA since last May. Means is a minor -125 favorite.

Round One: Means with a good 1-2 out of his southpaw stance and follows up with hard uppercuts inside. Lima crumbles to the mat but gets right back up. Means mixing his combo’s up with elbows and knees. Lima with a hard right to back him up briefly but gets tagged with a knee to the head in the clinch. Straight left staggers Lima, Means with a few punches, and that’s it! Dean steps in.

Tim Means defeats Dhiego Lima by TKO (punches) at 2:17 of round one.

Ariel Helwani announces this is the first UFC to receive both blood and urine testing for all competitors.

Bantamweights: Roman Salazar vs. Norifumi “Kid” Yamamoto

The 37 year old Tokyo native Kid was a legend in an earlier era, using a high caliber of wrestling with some solid boxing. He’s a -160 favorite vs. “El Gallito” Salazar, of Arizona.

Round One: The two bounce in and out, with Kid shooting punches from long range and missing. Salazar finally starts looking for inside leg kicks and body kicks after almost two minutes. Right hook from Southpaw Kid. And another. Eye poke from Salazar halts the action. Yamamoto fighting in spurts but still way outlanding Salazar. 10-9, Yamamoto.

Round Two: Salazar catches a Kid kick and gets a takedown. Kid back up. They’re back to darting in and out, Salazar in defensive shell. Kid with a lunging uppercut. Salazar is hit with an eye poke and the action is halted. More of the same darting in and out. Kid glances a haymaker. Salazar is poked in the eye again.

Fight is stopped and declared a no contest.

Roman Salazar and Norifumi “Kid” Yamamoto fight to a no-contest (accidental eye poke at 2:37 of round two).

Middleweights: Mark Muñoz  vs. Roan “Jucao” Carneiro

Jucao is a BJJ black belt fighting out of Georgia. SoCal based GnP specialist Muñoz is a -285 favorite.

Round One: Jucao sprawls out of a takedown, scrambles into side control. Jucao moves to back and quickly gets the rear naked choke. Muñoz out cold!

In fact, he was out several seconds before the ref intervened. Bad job by officials tonight, but good win for Jucao, who actually let up on the choke as he realized Mark was out. Also very respectful to his opponent post-fight, saying he’s a big fan. Good stuff.

Roan “Jucao” Carneiro defeats Mark Muñoz by technical submission (rear naked choke) at 1:40 of round one.

PPV broadcast up next.

Main Card (to be broadcast on PPV)

Lightweights: Tony Ferguson vs. Gleison Tibau

Ferguson gets a nice hand fighting in his hometown — will enjoy a 6″ reach advantage here. Brazil’s Tibau is making his 25th UFC appearance.

Round One: Good punching and fornt kicks at range from Ferguson. Tibau, fighting about a 40 day turnaround, struggling to get started. Tibau hits the deck off a right. Big right cracks Tibau. Ferguson looking for a choke on the mat… then spins to Tibau’s back. Ferguson gets the choke and the tap!

Tony Ferguson defeated Gleison Tibau by submission (rear-naked choke) at 2:37 of round one.

Welterweights: Alan Jouban vs. Richard Walsh

SoCal Male model Jouban is a -335 favorite over Aussie Walsh, who has a Muay Thai background.

Round One: Walsh with a heavy kick to the southpaw Jouban’s body. They clinch but disengage right away. Good body kick from Jouban; right hand lands from Walsh. Walsh with the pressure with hand combo’s. Jouban with a good body kick. Straight left lands from Jouban, then a big elbow! Walsh crumbles to the mat and the ref stops it!

Alan Jouban defeated Richard Walsh by TKO (elbow, punches) at 2:19 of round one.

Welterweights: Jake Ellenberger vs. Josh Koscheck

Two former contenders trying to get out of a three-fight losing slump here. Ellenberger is a -210 favorite.

Round One: Ellenberger looking for the jab. Koscheck with a high kick, which is blocked. Kos shoots in and gets a takedown. Ellenberger trying to wall-walk… finally works to his feet. Little stomps and knees in the clinch from Kos. The action is slow and the crowd is booing. Halfway through the round, Ellenberger spins away. Ellenberger looking for the jab. Ellenberger lands a right. Kos a little wobbly, circling away now. Koscheck, 10-9.

Round Two: Kos trying for another takedown, gets Ellenberger against the cage. Ref breaks ’em up. Kos circling away again, seems he’s bleeding and bothered with his left eye (hit by that right last round). Ellenberger with a minor advantage as they slowly attack with hand combo’s. Boo birds out in force now. Ellenberger snares Kos in a power guillotine — similar hold as a rear naked choke — and Kos taps!

Jake Ellenberger defeated Josh Koscheck via submission (north-south choke) at 4:20 of round two.

(Co-Main Event) Women’s Bantamweights: Raquel Pennington vs Holly Holm

Holm a -650 favorite here, mostly for her boxing achievements. She uses traditional Irish music, while Pennington uses “Uptown Funk” — so that seems a mismatch too.

Round One: Holm striking wildly with kicks and punches — Pennington clinches up but her takedown attempt is shrugged off. Holm clinches, hits knees to the body. They disengage, side kicks snap out at range from Holm. Head kick from Holm, Pennington again fails with a takedown. Knee to the leg by Pennington. They disengage. Holm with light 1-2’s and that side kick as time expires. 10-9, Holm.

Round Two: Holm with more pitter patter punching and then a high kick. Pennington with a leg kick as she finally moves in… Pennington looking to walk her down, but not landing much. Slow action with a lot of darting back and forth. Holm is still in control though — lands a solid straight left in the mix, but overall there’s not much to see here. Good right by Pennington as the round ends. 10-9, Holm.

Round Three: More of the same, Holm landing a good 2-1 combo and a body shot. Pennington wakes up and scores a knockdown off a chopping right hand. Holm back up and lands a good punching combo. Knee to the body lands hard from Holm. Pennington misses a punching combo. 10-9, Pennington.

Not a great fight at all. Holm won on my card, but had some serious Octagon jitters.

Holly Holm defeated Raquel Pennington by split decision (29-28, 28-29, 30-27).

(Main Event) Women’s Bantamweights: Ronda Rousey vs. Cat Zingano

Here we go! Rousey with her typical “Bad Reputation” music on the entrance, looking typically focused. Cat pacing and staring back as the intro’s begin. I still think this is a bit of a mismatch but it’s a heck of an atmosphere.

Round One: Rousey clinches immediately, rolls to the mat, and clinches in the armbar. Cat taps out immediately. 14 seconds is all it took.

 Ronda Rousey defeats Cat Zingano by submission (armbar) at 0:14 of round one.
