It was announced at the Smackdown tapings on Tuesday night in North Charleston, South Carolina that the originally scheduled CM Punk vs. Ryback main event for the WWE Championship in a TLC match has been called off. Instead Ryback will team with WWE Tag Team Champions Team Hell No (Kane and Daniel Bryan) against The Shield (Dean Ambrose, Seth Rollins and Roman Reigns) in a six man tag team match at the PPV on 12/16.
The change was a result of CM Punk undergoing surgery on his left knee on Tuesday in Florida.
