To follow-up on CM Punk being removed from upcoming WWE dates, there doesn't seem to be anything to it. Apparently Punk being listed on the events in the first place was an oversight, something I mentioned in my original report, and nothing regarding his status has changed.
Punk is taking time away from the ring to heal from injuries, as he was actually pulled from live events prior to Wrestlemania 29 due to concerns regarding his health. His match against Undertaker only made his problems worse and by many accounts, Punk is lucky he didn't require surgery.
The former WWE Champion remains out indefinitely.
