As previously reported, CM Punk has been pulled from all live events leading up to WrestleMania so that he can be fresh for his match against The Undertaker at WrestleMania 29.
At this time, Punk is expected to remain off of the WWE RAW live events (house shows) following WrestleMania so that he can heal up from various nagging injuries. WWE feels CM Punk has helped carry the company in recent years, and are looking to give him the time off in order to protect their investment in him.
