It's the end of an era as Rob Gronkowski announced his retirement from the NFL on Tuesday.
Gronkowski called it a career after 11 seasons, nine with the New England Patriots and his final two with the Tampa Bay Buccaneers. The legendary tight end's entire Patriots tenure was spent with Tom Brady as his quarterback and Julian Edelman as a fellow pass-catcher. Brady also was Gronk's quarterback in Tampa, where he added a fourth Super Bowl ring to his collection.
Shortly after Gronkowski announced his retirement, Brady and Edelman shared heartfelt messages for their longtime teammate.
