Patriots tight end Rob Gronkowski was carted off the field at Gillette Stadium Sunday after being hit in the knee by Cleveland safety T.J. Ward with 8:27 remaining in the third quarter.
Gronkowski could very well be done for the season given the severity of the hit.
The big tight end missed the first six games of this season and last year's AFC Championship game against Baltimore due to injury.
