UFC middleweight champion Anderson Silva and training partner Lyoto Machida were all smiles following a recent session at Black House outside Los Angeles.



Both commented on each other's upcoming bouts -- Silva's against wrestler Chael Sonnen at UFC 117 on Aug. 7 in Oakland, Calif., and Machida's potential (and still rumored) tilt with Quinton "Rampage" Jackson.



The two Brazilian standouts also gave their impressions of Fabricio Werdum's stunning upset victory over Fedor Emelianenko at Strikeforce in June.
