Bills receiver Percy Harvin has been placed on injured reserve after a setback in his recovery from a knee injury.

Buffalo Bills receiver Percy Harvin has been placed on injured reserve after a setback in his recovery from a knee injury, the team announced Saturday.

Vic Carucci of the Buffalo Newsreported Friday that Bills general manager Doug Whaley said IR could be an option for the oft-injured Harvin, a move that would end his season. Whaley told reporters that Harvin’s knee had “flared up,” and that he would have a discussion with team trainers about his status.

The NFL Network reported in October that retirement was an option for Harvin, who has not played a full 16-game schedule since 2011 with Minnesota. Harvin has also dealt with a hip injury this season and has not played since Oct. 11 against Tennessee.

Harvin has recorded 19 catches for 218 yards and one touchdown in four games for the Bills. He will be a free agent at the end of the season.

Buffalo has been without Harvin and receiver Sammy Watkins for multiple weeks. Watkins said Friday that he will play Sunday against the Dolphins.
