Green is battling a concussion. He was unable to practice at all this week, so it seems unlikely that he will get clearance to play on Sunday. With Cedric Benson and James Starks also injured, DuJuan Harris and Ryan Grant will receive the bulk of the carries in Week 16.
Fantasy Impact: The Packers' running game hasn't produced much fantasy value this season. Benson was a decent second option at running back, but since his injury, no Green Bay ball carrier has emerged as relevant for fantasy purposes.
DuJuan Harris is worth a look in deeper leagues, as he has been impressive in recent weeks. If you need to take a flier, he's not a terrible option.
