Anderson Silva on Monday responded unlike ever before to rival middleweight Chael Sonnen, when he promised to "break his face and break every one of his teeth" in their upcoming rematch at UFC 148 on July 7.

The comments were made through a translator during a media conference call.

"What I'm going to do inside the Octagon is something that's going to change the image of the sport," Silva said. "I'm going to make sure every one of his teeth are broken, his arms are broken, his legs are broken.

"He's not going to be able to walk out of the Octagon by himself. I can guarantee that."

Silva (31-4) is widely considered the top mixed martial artist in the world. He has successfully defended the 185-pound title a UFC-record nine times since 2006, including a fifth-round submission win over Sonnen when the two met in August 2010.
