James Starks, who played in just nine games this season after knee and concussion problems, was cut by the Packers on Tuesday.
Eddie Lacy, who already has fallen behind James Starks on Green Bay's depth chart, is inactive Sunday against Detroit because of a groin injury.
James Starks has overtaken the struggling Eddie Lacy for the No. 1 running back role in the Packers' offense, according to coach Mike McCarthy.
