Eagles coach Andy Reid said that running back Dion Lewis, who was a healthy scratch, did not dress Sunday because rookies Bryce Brown and Chris Polk have earned the right to jump ahead of him on the depth chart.
He also noted that Lewis was slowed late in the preseason by a hamstring injury. Brown ran three times for 7 yards and was part of a fumbled handoff with Michael Vick. Polk took five special-teams snaps.
It's likely Lewis would get some committee action should McCoy suffer and injury and not be able to play.
