Dallas Cowboys running back DeMarco Murray will miss his fourth straight game Sunday against the host Philadelphia Eagles because of a sprained left foot, ESPN Dallas reported Friday. Murray did not practice this week but was seen Thursday wearing a helmet and cleats for his rehab. He spent much of Friday's portion of practice that was open to the media working out in the weight room. The team has said Murray cannot return until he is 100 percent and practicing. Felix Jones, who is listed as probable with a knee injury, is expected to start again in Murray's place after participating in practice this week.
