It's a well-known fact that former NFL player Rob Gronkowski, is a long-time WWE fan, having even come to the aid of his friend and WWE Superstar, Mojo Rawley, at WrestleMania 33.

Gronkowski helped Rawley win the André the Giant Memorial Battle Royal after he attacked Jinder Mahal in the ring.

And following his retirement, there has been a lot of buzz about him making the switch over to the WWE. Stephanie McMahon congratulated him and even said that the "doors are always open" for him in the WWE.

Congratulations @RobGronkowski, this is a tremendous honor by one of my favorite organizations, @USOMetroDC, dedicate to serve those who serve and their families. Thank you for all that you do and good luck with your retirement! Doors are always open @WWE! :))) https://t.co/nLYssgCJdV

Former Universal Champion spoke about the former NFL star in a recent interview, calling Gronkowski a "great athlete".

"It's hard to tell with him. He seems like a crazy enough guy. He seems like he's wild enough and has a great personality. He's clearly a great athlete," said Reigns.

Rawley has not been seen on RAW lately, but could the signing of his friend reinvigorate his WWE career? A tag team of Rawley and Gronkowski could work for both Superstars.
