UFC Bantamweight champion Ronda Rousey didn't need her savvy judo game in her ninth career bout, as she utilized brutal knees to the body to stop Olympic wrestling silver medalist Sara McMann one minute and six seconds into the first round of Saturday's UFC 170 main event in Las Vegas.  Rousey said she'd sparred her entire preparation camp. This is the first of Rousey's bouts that she hasn't ended via armbar. Check out SI.com's round-by-round recap of the entire main card below.

Women's Bantamweight Championship: Ronda Rousey vs. Sara McMann

Sara McMann is the only challenger with similar Olympic credentials to Rousey. She’s a 2004 Olympic silver medalist (7-0) with obvious physical strength, something that might make a difference against Rousey, who’s been able to bully her previous opponents. McCann’s preference is top control and some good ‘ole ground-and-pound. The problem is Rousey (8-0) can maneuver her armbar assault from just about any position. The X-factor is the stand-up (neither woman is an ace there yet) and Rousey’s movie star distractions. No matter what she says, she hasn’t had the dedicated time to work her weak spots. Will McMann be able to capitalize?

11:47 p.m. - Main event time. Sara McMann enters first with a T-shirt that reads "ETG." Embrace The Grind. Rousey follows, mean-mugging an invisible opponent in front of her.

11:55 p.m. - The women take center for instructions.  They touch gloves. Our referee is Herb Dean.

R1 – It’s a brawl from the get go, both women throwing for the fences. McMann gets in the best strike and Rousey pushes it to the fence. McMann is defending well; Rousey is attacking with knees. Rousey throws a vicious body knee and McMann crumbles, her arms grasping her mid-section (liver shot). It’s all over.

 Official Result - Ronda Rousey def. Sara McMann - TKO (knee) 1:06 R1

Light Heavyweight: Daniel Cormier vs. Patrick Cummins

Though Cormier and Cummins have gone above and beyond to promote this bout, it’s hard to get excited for a last-minute replacement fight between a 4-0 newcomer and a 13-0 contender on the outskirts of the contender’s circle.

Regardless, the two have had “beef” this week: the short of it is Cummins, a two-time All-American, made Cormier cry during an especially grueling wrestling session when Cormier was training for his Olympic bid. Apparently, UFC President Dana White booked the fight on this story. I’d gripe about this move, but why bother? Cormier has a good shot of knocking Cummins out.

11:29 p.m.  - Goldie and Rogan going into overdrive to hype this next one. "Make no mistake. Pat Cummins deserves to be in the UFC," says Rogan. At this point, everybody is making it into the UFC.

11:34 p.m.  - Cormier jogs quickly to the Octagon. He looks determined. Cormier makes his Octagon lap. He looks all business; borderline peeved. Our referee is Mario Yamasaki.

R1 – Cormier shrugs off Cummins half-shot. Cormier with an uppercut that hurts Cummins off the bat. Cormier taking his time. Cormier lands a left-right and Cummins goes down. Cummins turtled and Cormier lays on the hurt. This is over in no time.

Official Result: Daniel Cormier def. Patrick Cummins  - TKO (strikes) 1:19 R1

Welterweight: Rory MacDonald vs. Demian Maia

This is the first bout on the card tonight that has actual ramifications for its division. Let’s start with Rory MacDonald (15-2), touted as the second coming of Georges St. Pierre, his mentor. MacDonald lived up to the hype with decision wins over Jake Ellenberger and B.J. Penn, but hit a brick wall with Robbie Lawler last November – a split-decision loss that cost him a title shot now that GSP has stepped down as champ. MacDonald had his hands full with Lawler; he needs a decisive showing tonight to get back in the title hunt.

BJJ master Maia (18-5) was on a roll in his drop to 170 with back-to-back wins over Dong Hyun Kim, Rick Story, and Jon Fitch (February 2013). His split-decision loss to Jake Shields last October slowed down that train. Taking MacDonald out will get things back on track, though the young Canadian is quick on his feet.

Mike Pyle vs. T.J. Waldburger 

The 38-year-old Pyle (25-9) is entering the final phase of his career on a respectable note. He’s won four of his last five UFC bouts (eight of his 12 UFC appearances); Matt Brown took him out in the last with a 29-second KO six months ago. A win over Waldburger won’t put Pyle any closer to title contention…

…but Waldburger (16-8) stands to gain more with a win over the veteran Pyle. The 25-year-old Texan is also coming off a first-round KO loss – his to Adlan Amagov last October.

10:28 p.m. - Waldburger enters first to ACDC. Pyle enters with a big smile and his magic mullet. Our referee is Herb Dean.

10:52 p.m.: "His leg quicks were hard. We expected a battle and we got it," says Pyle. Will Smith and Jada Pinkett-Smith flash across our screen.

Official Result: Mike Pyle def. T.J. Waldburger  - TKO (strikes) 4:03 R1

Welterweight: Stephen Thompson vs. Robert Whittaker

“Wonderboy” Thompson (8-1) has rebounded well enough from his sole career loss to Matt Brown last April with victories over Nah-Shon Burrell (May 2013) and Chris Clementes (Sept. 2013). He has potential in the division -- especially as a quick, crowd-pleasing striker -- but needs more time for development.

Whittaker (11-3) should be a fine challenge. He took gritty TUF winner Court McGee to task last August, narrowly dropping a spilt-decision loss to the tough-as-nails fighter.

R1 -  Whit takes center cage. Whit in with a jab; Thompson taking side stance. Good pace from both to start. Thompson with a right hook; then a left a few seconds later. Thompson landing front, side kicks; Whit has slowed down his attack. Thompson forward with a landing combo. Whit starting to chase Thompson down; lands here and there, but Thompson is generally circling out. Thompson with hook kick. Thompson standing in front of Whit, doesn’t look afraid of Whit’s striking. They continue to exchange. Thompson lands a big right straight and Whit goes down, tries to get his feet and is knocked down again in the Thai clinch with knees. Follow-up shots and referee Yamasaki stops it.

Official Result: Stephen Thompson def. Robert Whittaker - TKO (strikes) 3:43 R1

10:23 p.m. – Thompson very polished in his post-fight interview. Stone Cold Steve Austin and UFC lightweight champion Anthony Pettis in the house.
