Rob Gronkowski has yet to file his retirement paperwork, Robert Kraft told the NFL Network on Thursday.
Gronkowski, who recently joined FOX's broadcast team, said he doesn't have plans to return, but Kraft said, "We can pray and hope."
When asked about Kraft's comments, Gronkowski said about the possibility of coming back from retirement: "I would have to be feeling it, feeling it big-time to come back. It's always going to be open in my mind. ... I love the game of football. I love playing the game. I love being around the game. I even love watching the game of football now."
