John Cena has posted CM Punk's Twitter profile picture on his Instagram. Punk has been using the picture of Paul Newman in Slapshot for the last year, and fans have started fervently speculating on why Cena would now post the same picture. If you remember last month, before AJ Styles joined WWE, Cena posted a Styles photo on his Instagram. Is he now trying to drop a similar hint indicating CM Punk is coming in? It would seem unlikely, more probable is that Cena is having fun and teasing the fans. Punk is under contract to UFC and has just had a small surgery. He's also had legal problems with WWE's doctor and left the company on incredibly bad terms two years ago. That said, some fans are convinced Cena is dropping a hint here. He often posts abstract pictures to his Instagram as a way of communicating cryptic messages. You can understand why some fans believe this copy of Punk's Twitter picture is a clue just like the Styles photo was. What's also causing Cena's post to be talked about, is the fact that Dave Meltzer reported The Undertaker's WrestleMania opponent this year is someone who isn't active with WWE. CM Punk would certainly fit that bill, although he did work the Deadman at Mania just three years ago. What do you think? Have WWE tempted CM Punk back with a WrestleMania show closing main event against The Undertaker? Or is John Cena's Instagram post just a random bit of fun?
