John Cena is currently out with a shoulder injury, which means he has more time in his hands. The 15-time WWE champion is a known active user of Instagram and decided to send internet fans into a frenzy by posting the following photo last Feb. 20.

CM Punk Returning to WWE?

Here comes the rumors that CM Punk is returning to WWE as many fans are still hoping that the former wrestler will be back in time for WrestleMania 32. However, it should be noted that Punk, real name Phil Brooks, is currently signed to a multi-fight contract with the UFC.

He has recently undergone back surgery and is scheduled to make his MMA debut against Mickey Gall probably sometime later this year. He also has an ongoing legal battle with WWE's doctor as well as famously walking out of the company that led to a very bad relationship.

However, many believe that Punk may be back in wrestling as Dave Meltzer reported that The Undertaker's WrestleMania 32 opponent is not an active WWE superstar. Punk seems to be the perfect fit, but he has already faced The Undertaker at WrestleMania 29 last 2013.

John Cena is Just Trolling

"Welcome to my Instagram. These images will be posted without explanation, for your interpretation. Enjoy." These are the exact words in Cena's Instagram description, so he could very well be just trolling fans for his entertainment.

Although some of his cryptic posts became true just like with A.J. Styles, it's difficult to believe that CM Punk will be back in the WWE. He has said a lot of negative comments and harsh words towards the company these past years.

In relation to his Instagram, Cena recently posted an image of The Undertaker, who was his rumored opponent at WrestleMania 32 before he got injured.

Cena vs. Taker at WrestleMania?

The 38-year-old superstar was present at the Daytona 500 this Feb. 21, where he spoke about a possible return at WrestleMania in Dallas.

"As far as me participating in WrestleMania 32, the Magic 8-Ball says 'Ask Again Later.' It would be personally unfortunate for me to miss WrestleMania. Our goal is to deliver the best show possible. If I can contribute to that, great. If I can't then, we'll see how it works," Cena commented.
