With the majority of their wins coming in the first round, not many fans were expecting the heavyweight championship bout between Junior dos Santos and Frank Mir to go the distance Saturday night.
After an early feeling out process, Dos Santos established his attack and showcased the boxing skills that have taken him throughout his UFC career to winning the title last year.
Mir couldn't survive the punching power of his Brazilian opponent, losing by TKO in the second round at UFC 146 in Las Vegas, Nev.
It was the main event of an all-heavyweight pay-per-view and gave fans of combat sports what they want to see from the heavyweights in a knockout.
Round 1 was back and forth until the last 20 seconds when Dos Santos landed a flurry of punches that hurt Mir.
Early in the round, Mir attempted a takedown but was unsuccessful and tried to transition to a leg lock. JDS was able to escape and get back to the feet where he could be at his most comfortable.
With his body shots and flurry at the end, JDS stole the round.
Round 2 opened with Mir getting dropped early by a right hand. After a quick recovery, Mir started to use more leg kicks to keep distance between him and his opponent.
With brutal body shots, JDS created the opening for his right hand, knocking Mir down three minutes into the round after countering a kick.
A quick hammerfist to Mir's head left Herb Dean no choice but to stop the fight.
Junior dos Santos defeats Frank Mir by TKO at 3:04 of Round 2.
"I'm feeling awesome," Dos Santos began in his post-fight interview with Joe Rogan, via Toronto Sun. "Not bad for a nice guy."
Heading into the bout, much of the hype for the fight came from Mir's two victories against Dos Santos' mentor, Antonio Rodrigo Nogueira.
"Nogueira is a tremendous fighter," Dos Santos said of the fights. "Frank Mir is a really good fighter, too. That fight is between them. I respect my mentor, but I came here to defend my belt, and I did it."
Now the question is who's next?
Of all the heavyweights that won tonight, three have already fought him. Many are anticipating a rematch with Cain Velasquez.
Mir's third attempt at gaining the heavyweight championship ended with him getting knocked out for the sixth time in his career.
It's hard to think he gets another shot at it, but this is the heavyweight division and one win can change any fighter's chances.
"He's the champ," Mir said after the fight. "He's faster. I couldn't get out of the way. It was some of the hardest shots I've ever taken."
"I knew he would be hard to takedown," said Mir. "I didn't want to box with him. He just forced me to because I couldn't get him down."
If Mir continues to try to get back into contention, it could start with a fight with Antonio Silva, who lost to Cain Velasquez in the co-main event.
