CM Punk is said to be relaxed and refreshed following his near two month sabbatical from WWE. We still do not have confirmation but continue to operate under the assumption he will work against Chris Jericho at Payback on Sunday.
He has plans to attend Wednesday's Stanley Cup Finals Game 1 between the Boston Bruins and his hometown Chicago Blackhawks. Punk was in Detroit on Tuesday night at a concert at The Fillmore (details here). Punk doesn't take much solace in the ratings being in the toilet without him but would love to show Vince McMahon that he can move the needle.
The feeling is Punk eventually wants a program with Daniel Bryan and if he can't get a match against Brock Lesnar at Wrestlemania XXX, he'll lobby to work Bryan and steal the show. Punk's hair is a little longer and he got some new tattoos during his time off.
As for his health, Punk is said to be in a "much happier place" and his knee is a lot better. It isn't 100% and might not be without surgery but it's good enough to resume working in the ring.
