- We noted earlier that ESPN Cleveland reporter Casey Kulas reported the following about a backstage argument CM Punk had with WWE officials at RAW:

"My info on CM Punk: I do know from sources that at #Raw in CLE there was heated exchange backstage between Punk & staff. Topic – concussion. Punk was heard arguing with staff saying "I passed all your damn concussion test" and "I'm not going out and telling fans that BS""

In regards to that story, Punk was banged up in the Royal Rumble match on Sunday and did take a concussion test on Monday but it showed that he did not have a concussion. The concussion test had nothing to do with his departure.
