Gonzaga celebrates UFC return (Getty)

Back in 2010, Gabriel Gonzaga lost his confidence and his passion. He got both back tonight in Rio de Janeiro.

The former heavyweight title contender schooled hotshot prospect Edinaldo Oliveira in less than four minutes. Gonzaga made it look easy as he took the 6-foot-7 Oliveira to the ground and eventually locked on a nasty rear-naked choke to force the tap at 3:22 of the first round.

"It felt great to be back in the Octagon. My time away from the UFC was good for me. I dealt with some personal business in my life and came back refocused. Before, I was training well, but my mind just wasn't in it. Now, I'm back, I feel great. I'm focused and I showed that," said Gonzaga.

Gonzaga (13-6, 8-5 UFC) last fought with the promotion in Oct. of 2010, then abruptly retired. He had a comeback fight with a smaller promotion in October of 2011.

After starting off 4-0 with the promotion, he rose near the top of the division, but then lost badly to UFC heavyweight champ Randy Couture at UFC 74. After that fight, Gonzaga looked tentative and wilted in big moments going just 3-4.

Oliveira (13-2, 0-1 UFC) was way in over his head tonight. He looked to small for the weight class and his takedown defense was shaky. Once Gonzaga got him to the ground, Oliveira was easy prey.

Stout tentative in first fight since trainer's passing

This was going to be a tough night for Sam Stout. He was facing Brazilian Thiago Tavares on his home turf and doing so without his trainer Shawn Tompkins, who passed away last August.

Mike Pyle celebrates after winning at UFC 142 (Zuffa)The UFC returned to Brazil on Saturday night for UFC 142. Two decisions and a quick knockout started off the card in Rio de Janeiro.

Pyle's quick win

Mike Pyle made quick work of Ricardo Funch with a right hand, a nasty knee and ground and pound to end their bout at 1:22 in the first round.

After the bouts, Pyle put out a warning to other welterweights.

"That's how I'm going to look every single time I step in the Octagon!"

Yuri Alcantara made the hometown crowd happy with a 30-27, 29-28, 30-27 decision over Michihiro Omigawa.

Alcantara started with a knee from the bell, and stung Omigawa with several strikes after. Late in the first, Alcantara swarmed with big strikes, including a spinning back elbow that knocked Omigawa to his knees. Omigawa remained calm and used his judo skills to reverse position and end up on top. Alcantara turned stretched out Omigawa in an armbar, but Omigawa was saved by the bell. A bit of controversy ensued as there was a question on if Omigawa tapped, but he didn't and the bout continued.

Belfort and Johnson square off at UFC 142 weigh in (Getty)

The debate has raged all day - how will Anthony Johnson's weight snafu affect his fight against Vitor Belfort? The pulse in the betting world is that Johnson is in big trouble at UFC 142 in Rio de Janeiro.

Belfort's number has jumped 40 cents since it was announced Johnson couldn't make the 186-pound weight limit at middleweight. He actually stepped on the scales yesterday in Rio de Janeiro at 197 pounds. A stipulation was also put in place that Johnson couldn't replenish his body beyond 205 pounds for another weigh-in earlier today.

If you liked Aldo early in the week at minus-220, you missed your chance. There's been heavy fight day steam on Aldo pushing him to minus-275.

Listen to Yahoo! Sports Kevin Iole, Adam Hill from the Las Vegas-Review Journal give out picks for the top fights on the card during last night's "MMA Insiders" show on ESPN1100/98.9 FM in Las Vegas.

Dana White's latest vlog does a nice a job of showing behind-the-scenes coverage of how the Anthony Johnson weigh-in miss went down.

Vitor Belfort arrives at the arena (2:45 mark) and is blown away by the fact that Johnson wasn't going to make weight. He explains that his cut was tough. As he thinks about what to do, Belfort begins to intensely chew on a towel full of ice to get a little water into his system.

White gives him the option of not making weight either, but then he wouldn't get 20 percent of Johnson's purse. His nutrition coach Mike Dolce is brought into help make a decision and says Vitor is going to be professional and do his part.

Later in the video, Johnson is informed on stage that he has to weigh in again on Saturday and be under 205 pounds. The exchange between White and the fighter is cordial.

Despite being a devastating knockout artist in the cage, Junior dos Santos is a smiling, affable man outside of it. He, UFC lightweight Gray Maynard and Octagon Girl Arianny Celeste stopped by a surfing school in Rio de Janeiro, Brazil as part of the run up to UFC 142 this weekend. They met with the students and even tried surfing.

If you're wondering what it looks like when a heavyweight champion surfs, here you go:

And yes, if the champ makes it to his feet on dry land, he will get applause. That's just how it goes. He gets extra credit for pulling off the Ron Santo-esque heel click.

What the heck just happened? Insert some stronger language and that had to be Dana White's initial reaction to Anthony Johnson's huge gaffe at the UFC 142 weigh-in.

Johnson, a massive 170-pounder, took this fight at 185 pounds months ago. Thought by some to be the smaller fighter against Vitor Belfort, Johnson clocked in at a shocking 197 pounds! The backstory was that Johnson got as low as 187.5 and doctors told him to stop.

UPDATE: Here's the medical explanation why Johnson stopped cutting weight at 187.5 pounds.

White was alerted to the issue earlier in the day and announced right around 4 p.m. ET that Johnson wasn't going to make weight.

"Rumble Johnson is not on weight today. And when I say he's not on weight he's way off weight," White said on FX.

White rightly flips out when fighters miss weight by three or four pounds. This was 11 pounds (186 is allowable middleweight limit)!

"As a fighter, you are a professional. You are contracted to come in at a certain weight. This is not the first time this has happened with Johnson. He moved up to 185 pounds so this wouldn't happen to him at 170 pounds, and here we are in the same position again. [Belfort] came in like a professional on weight, and Anthony Johnson comes in as a total unprofessional, way overweight."

The next step to officially making the fight tomorrow is also mind-blowing. Fighters like to rehydrate and replenish their body after the weigh-in. Johnson has to watch his intake. If he balloons higher than 205, Belfort said he won't take the fight.

"The stipulation is, Vitor does not want him to weigh more than 205 pounds by tomorrow at like 2 o'clock in the afternoon," White said. "So we'll see how this thing plays out. He'll weigh in today and have to weigh in tomorrow."

Johnson was making his debut at middleweight after waging his previous 10 UFC fights down at welterweight. The 27-year-old will be fine 20 percent of his show purse. If he loses badly, he may have to worry about a pink slip arriving soon from the promotion. Let's hope there was some legitimate excuse that can excuse Johnson's big mistake.

Mike Pyle has fought all over the world, but even he admits tomorrow night at UFC 142, Rio de Janeiro could be unlike anything he's ever seen.

"We're fighting and we have to fight other countryman on their soil. That makes it fun. Get out there in some hostile territory," Pyle told ESPN1100/98.9 FM. "It's kind of different. You don't get booed and looked at in strange ways at home. It's cool. Makes me feel like a super villain."

Pyle won't be walking through the Rio crowd with complete unfamiliarity. He cornerd Forrest Griffin back at UFC 134 and saw how intense the Brazilians were that night.
