This was all planned
I have been away from boards for a few weeks but this whole Punk injury has been planned, right? That's why they introduced the Shield, right? To get a interesting Ryback match. Also, if you noticed, before they announced the injury, only Kane and Bryan made the save, not Randy Orton. He was attacked that night as well. All this time, they weren't really working an angle for Team Hell No.
Is Punk really hurt? Are they keeping him out of Ryback's way so they don't hurt Ryback's character and keep Punk vs. Rock.
