Rob Gronkowski is no longer "shackled" by the NFL and the New England Patriots -- and that means we could see him RUN WILD in the WWE very soon ... so says his good friend, Mojo Rawley.
Everyone knows Gronk LOVES pro wrestling -- remember he made a cameo with Mojo at Wrestlemania 33 in 2017 -- and people are speculating he could become a WWE superstar now that his NFL career is over.
We spoke with Mojo, who says he wouldn't be shocked if Gronk turned his focus to the ring .
