The Packers will be without rookie running back Eddie Lacy for Sunday's game against the Bengals.

Lacy sustained a concussion a week ago against the Redskins, when safety Brandon Meriweather led head-first and collided with Lacy's helmet. The hit knocked Lacy out of the game and for this week too.

James Starks will take over No. 1 running back duties with Lacy out. A week ago, Starks ran for 132 yards and a touchdown on 20 carries against the Redskins.
