"Mr. Sunshine" Steve Cofield has the "raw" audio feed from the UFC 83: "Serra vs. St. Pierre 2" post-event press conference.
Georges St. Pierre, Matt Serra, Rich Franklin, Michael Bisping, Nate Quarry, Mac Danzig and UFC President Dana White all participated.
Serra talks about the stoppage, admitting that St. Pierre was beating him up but he seems a bit confused regarding the referee's decision to step in and stop the fight in the waning seconds of round two.
