Beatdown: GSP and Matt Serra

TJ De Santis and Josh Gross returned on Wednesday, and were joined by UFC welterweights Matt Serra (Pictures) and Georges St. Pierre (Pictures).

Serra, the Octagon 170-pound champion, discussed the back injury that forced him to withdraw from his late December bout with Matt Hughes (Pictures). Taking his place to square off with Hughes is St. Pierre, who joined De Santis and Gross to chat about the interim title clash.
