Patriots tight end Rob Gronkowski is done for the day after being carted off with a knee injury.
Update from the #Patriots bench: Rob Gronkowski will not return to the game due to a leg injury.
It was thought that Gronk was knocked out, but suffered a knee injury, not a head injury.
Update: Gronk will undergo an MRI on his knee on Monday, but right now it doesn’t look good.
Update: It’s believed that Gronkowski has suffered a torn ACL.
