That's Chael Sonnen cracking Anderson Silva's granite jaw on Saturday. Of all the hard hitters he's faced in the UFC, Sonnen is the first to rock him.

So, that was the second time in the 1st round he caught a kick and didn't follow it up. There was a good second there where he could have followed it up with a straight right (his broken rib side, mind you). That makes me believe that the rib had a big impact on Silva' performance.
