IRVING, Texas - Cowboys running back Felix Jones is listed as questionable for Saturday's game against the Eagles after missing practice all week because of hamstring tightness.
The NFC East-leading Cowboys had said during the week they were being cautious with Jones, who was limited to working on the side but never got on the field for practice. He is coming off consecutive 100-yard rushing games since rookie DeMarco Murray, the team's leading rusher, broke his right ankle in the first quarter of a loss against the New York Giants two weeks ago and was put on injured reserve.
During one of his regular weekly radio appearances Friday, Cowboys owner Jerry Jones said he would be surprised if Felix Jones didn't play. But the owner also said it was important to have a backup plan, since the fourth-year running back hadn't practiced.
Sammy Morris, a 12-year NFL veteran who signed with Dallas and made his season debut last week, would start if Jones doesn't play. Later Friday, the Cowboys signed running back Chauncey Washington to the active roster from their practice squad.
Morris and Washington split time at practice in Jones' absence.
Linebacker DeMarcus Ware (neck stinger) and nose tackle Jay Ratliff (ribs) were also listed as questionable, but both are expected to play after having limited participation three days in a row. Ware and Ratliff both played with those lingering issues in last week's win at Tampa Bay, though they came out after the Cowboys built a 28-0 halftime lead.
Dallas also listed as questionable cornerback Mike Jenkins (shoulder), safety Danny McCray (ankle), and receivers Kevin Ogletree (knee) and Laurent Robinson (shoulder). McCray and Ogletree didn't practice this week.
Nose tackle Josh Brent is out with a knee injury.
Washington, whose only four NFL carries came as a rookie for Jacksonville in 2008, was signed to the Cowboys' practice squad Nov. 30. He had been out of football since being cut by St. Louis during training camp on Aug. 4.
