The UFC heavyweight championship belt is finally staying with the same owner for more than one fight.

The golden strap is headed back to Salvador, Brazil, with Junior dos Santos. Former champion Frank Mir was no match for dos Santos, who officially claimed a second-round TKO victory at 3:04.

"I came here to defend my belt," dos Santos exclaimed in the octagon moments after his victory, "and I did it."

Dos Santos breaks a streak of four straight challengers prevailing in UFC heavyweight championship fights. It's the first time in two years — since Brock Lesnar, who sat octagon-side with UFC President Dana White — that anyone has defended the most prized possession in the promotion.

Dos Santos dropped Mir with a counter right-hand in the second round. A few seconds later, it was over after dos Santos chased after him and rained down punches on the grounded Mir.

"It's not bad for a nice guy, huh?" dos Santos said.

Another nice guy, former champion Cain Velasquez, also had quite the night. Velasquez defeated Antonio "Bigfoot" Silva by TKO at 3:36 of the first round in the co-main event.

In perhaps the bloodiest heavyweight fight in UFC history, Velasquez opened a deep cut above Silva's eye. The octagon newcomer bled profusely, eating elbows and ground-and-pound punches, before the referee mercifully stopped the fight.

"I took my time and waited to get good position to turn it on and finish the fight," Velasquez said. "I had to get really good posture and sit up in order to get power and land those hard shots. I knew if I kept the speed up the ref would step in and stop it."

Mir may have come up short in his quest to win a title, but another local was successful on the card. Roy Nelson knocked out Dave Herman with a right hand 51 seconds into their bout.

The win breaks a skid that saw "Big Country" lose three of his past four bouts. Stipe Miocic and Stefan Struve also picked up stoppages by beating Shane del Rosario and Lavar Johnson, respectively, to open the card.

Pre-main card

On the Saturday of Memorial Day weekend in Las Vegas, the ultimate gamble is taking place inside of the MGM Grand Garden Arena.

The UFC’s decision to hold its first-ever all-heavyweight main card looks like the ultimate hit-or-miss proposition. In terms of stirring interest, it’s a knockout of an idea.

The heavyweight division continues to hold the most pizzazz in combat sports. The fights often deliver, and fans love nothing more than seeing 250-pound men wing punches with all their power at each other.

But heavyweight fights also end disappointingly at a higher clip than the rest of the divisions. The aforementioned heavy power that enthralls fans can also cause bouts to end before they ever really get started — see the one-minute knockout at UFC on FOX 1.

Heavyweights tend to get tired faster, too, sometimes creating slow, sluggish wars of attrition — see the two heavyweight bouts on the main card of UFC 135 last week.

But all of this was a risk worth taking for the UFC. The fans, which have already filled the arena, also give the impression that they are unconcerned.

They don’t seem to mind the massive re-shaping of UFC 146 following Alistair Overeem’s failed drug test, either. On paper, Junior dos Santos gets a much easier opponent for his first title defense.

Dos Santos was only a 2-to-1 favorite over Overeem, but oddsmakers see him as more than double that at 5-to-1 against Las Vegas native Frank Mir.

Mir’s ability to take a punch worried many UFC fans. Antonio Rodrigo Nogueira rocked Mir before he came back to get a submission in their last fight. Shane Carwin and Brock Lesnar also memorably made quick work of Mir within the last three years. But Mir has referenced recent wins over Roy Nelson and Mirko Cro Cop for proof that he has a strong enough chin.

Mir says wrestling is his biggest disadvantage, so perhaps he dodged a bullet by getting pulled out of a co-main event showdown with Cain Velasquez, who now meets Antonio “Bigfoot” Silva.

The more competitive matchups, by the odds, come in the first three pay-per-view fights. Cimarron-Memorial graduate Roy Nelson faces Dave Herman in a battle between two fighters looking to get back on the winning track.

Top prospects Stipe Miocic and Shane del Rosario meet in a bout that will give one of them a major boost toward their championship aspirations. The same could be said for the opening contest between Stefan “Skyscrape” Struve and Lavar “Big” Johnson.

Struve and Johnson are both on two-fight winning streaks and promised top opposition with another win.

Combined, around 2,500 pounds worth of heavyweights will enter the octagon tonight. Whether they soar or tumble will serve as the story of the night.

Welcome to UFC 146.

Stay tuned for a round-by-round live blog of the main card and read below for full results from the preliminary portion of the event.

Darren Elkins won a unanimous decision (29-28, 29-28, 29-28) over Diego Brandao in a featherweight bout. Brandao rocked Elkins several times in the first round, but the former lightweight was able to wrestle "The Ultimate Fighter" 14 champion and use ground-and-pound to win the rest of the fight.

The return of former WEC lightweight champion Jamie Varner was a rousing success. Varner stunned previously undefeated Edson Barboza, scoring a knockout victory at 3:23 of the first round. Varner finished Barboza with a combination of punches along the fence, and also took down the Brazilian prospect earlier in the round.

Jason "Mayhem" Miller promised he would retire from mixed martial arts if he lost to C.B. Dollaway at UFC 146. It's time to see if Miller, now 0-3 in the UFC, will stick to his word. Dollaway defeated Miller by unanimous decision (30-26, 29-28, 29-28), out-wrestling "The Ultimate Fighter" 14 coach to pick up the victory.

"It's really good to be back," former top welterweight contender Dan Hardy exclaimed after completing a sure Knockout of the Night candidate. Hardy knocked out Duane Ludwig with a left hand at 3:51 of the first round to snap a four-fight losing streak dating back to his failed bid to steal the title from Georges St. Pierre.

Paul Sass continued his tear of first-round submissions in the UFC with a victory over Jacob Volkmann. Sass submitted Volkmann with an armbar at 1:54 of the first round to stay undefeated. Sass has submitted all three opponents in the UFC and 12 out of 13 in his career.

Talk about a memorable UFC debut; Glover Teixeira showed why fans have demanded to get him into the octagon for years. Teixeira submitted Kyle Kingsbury with an arm-triangle choke at 1:53 of the first round after rocking the usually durable light heavyweight veteran with strikes.

Mike Brown won a unanimous decision (29-28, 29-28, 29-28) over Daniel Pineda in a featherweight bout. Pineda wobbled Brown with crisp striking in the first round and took the former WEC champion's back in the third round, but it wasn't enough. Brown prevailed in an exciting fight to open the card.
