Rob Gronkowski will undergo back surgery on Friday and is expected to miss two months.
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 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.
