Top middleweight contender Chael Sonnen told ESPN.com on Tuesday that he isn't the least bit worried about the threats UFC champion Anderson Silva directed at him Monday during a media call.

"He says he's going to knock out my teeth and break my jaw and break my head and all this," Sonnen said. "He acts like I've never been to the orthodontist.

"I've fought 49 men, all professionals. He acts like I've never had a jaw set before. He acts like I've never had my head stapled shut in an emergency room before.

"Who gives a damn? He can do all those things." he added. "But one thing he didn't say is that he's going to beat me. One thing he didn't say he'd break is my will. One thing he didn't say he'd do is win this fight. We'll be in the middle of a cage stupid; I'd expect you to do those things."

Silva (31-4) and Sonnen will meet in a middleweight title bout July 7 at UFC 148 in Las Vegas. It will be the second fight between them.

In their previous bout at UFC 117 on Aug. 7, 2010, Silva retained his 185-pound belt with a fifth-round armbar triangle.

Though Silva was able to apply that submission hold at 3:10 of the final round, Sonnen thoroughly dominated the fight up to that point.

Sonnen (27-11-1) has continued to verbally taunt Silva ever since. But the champion has shown little desire to respond in a similar fashion, until Monday.
