While Rob Gronkowski retired following the 2018 season, the door reportedly isn't closed on the former New England Patriots tight end making a return this season.

Florio added that the deciding factor could be whether Patriots quarterback Tom Brady appeals to Gronkowski to come back, given New England's dire tight end situation.
