Patriots wide receiver Julian Edelman underwent a knee procedure on Thursday morning, per ESPN's Adam Schefter.
The exact timetable for Edelman's return is unclear. He is expected to be out for “some period of time," including Sunday's game against the Bills, per Schefter.
Edelman has struggled to make a major impact in the passing game in 2020 outside of a 179-yard performance against the Seahawks in Week 2. The three-time Super Bowl champion has tallied just eight catches over the last four games but has failed to find the end zone in 2020.
