Gronkowski left Sunday’s game against the New York Jets with an injury. A source told Schefter that ultimately Gronkowski was diagnosed with a herniated disk. The need for surgery was first reported by The Buffalo News.
Gronkowski had returned to action Sunday after missing the team’s game the week before because of a chest injury.
Gronkowski played seven snaps in Sunday’s win over the Jets, leaving the game late in the first quarter as he walked off under his own power with members of the team’s medical staff. The team later announced he had a back injury during the game and would not return.
It was unclear on what play Gronkowski injured his back.
It could have happened on a third-and-7 play with 9:04 remaining in the first quarter, as Gronkowski was the intended receiver on a deep pass down the middle of the field as he dove for the ball.
But Gronkowski played one more series after that play, and was the intended receiver on an incomplete pass down the right sideline on third-and-4 before walking off with members of the medical staff.
Gronkowski and quarterback Tom Brady were not present for practice on Wednesday. Brady, who is listed as having a knee injury, returned to the field Thursday.
