And Silva kept his promise, landing a hard body shot in the second round that led to a TKO victory.

But the win didn't come easy for Silva, who was dominated in the first round. Sonnen started quickly, taking the champion to the mat. He then pounded Silva with punches and elbows.

In the second round, however, it was all Silva. He stuffed Sonnen's takedown attempts and landed a knee to the chest as the challenger was on the canvas after missing with a spinning backfist. Silva then hit Sonnen with several hard punches that forced referee Yves Lavigne to wave the fight off at the 1:55 mark.

After all the hostility between the fighters, Silva quickly moved to bury the hatchet once the fight was over.

"Chael fought me and I fought Chael," said Silva, who improved to 32-4 after successfully defending his 185-pound title for a UFC-record 10th time. "This is a sport. I have nothing against Chael.

"If you [Chael] would like to have a barbecue at my house, I'd like to have you over."

Sonnen, who harassed Silva over and over, was receptive of the champion's kind words.

"He gave me an opportunity," Sonnen said. "He didn't owe me anything. He's a great champion.

"He got me with a good knee."

Sonnen, who lost to Silva by fifth-round submission in their first meeting on Aug. 7, 2010, fell to 28-12-1.

The attendance for UFC 148 was a sellout of 15,016. The $7 million gate is largest in UFC history.
