New England Patriots tight end Rob Gronkowski is retiring from football.
Gronkowski took to social media last night and announced that this was the biggest decision of his life, but it's time to move forward.
Gronkowski says he's grateful for the opportunity given to him by owner Robert Kraft and head coach Bill Belichick.
Gronk says he moves forward with a big smile knowing the Patriots organization and fans will be a big part of his heart for life.
The team hasn't commented yet.
