IRVING, Texas (AP) -- Cowboys running back Felix Jones isn't at practice again.
Jones, coming off consecutive 100-yard rushing games for the first time in his four NFL seasons, is dealing with hamstring tightness. He wasn't on the field at the start of practice Wednesday after missing Tuesday's session.
Cowboys executive vice president Stephen Jones expressed confidence Felix Jones will play against the Eagles on Saturday and says the team is being cautious since they are so thin at running back.
Rookie running backs DeMarco Murray and Phillip Tanner are already on injured reserve. That leaves the Cowboys with Sammy Morris, a 12-year veteran, and Chauncey Washington on the practice squad.
