Cowboys make roster move: Promote RB

IRVING -- The Cowboys announced a roster move on Friday, placing rookie defensive end Sean Lissemore on injured reserve with an ankle injury and promoting running back Lonyae Miller from the practice squad.

Miller's promotion could mean starting running back Marion Barber will not play Sunday at Indianapolis because he's nursing a strained left calf.

Currently the Cowboys have two healthy running backs on the active roster in Felix Jones, the leading rusher and backup Tashard Choice.
