Murray has missed six straight games since spraining his foot in Week 6 in Baltimore, and the Dallas running game has struggled for consistency in his absence. Jones said he can't be sure Murray will be ready for next Sunday's game against the Eagles. "We can't get a prognosis that another week's rest will do anything"” Jones said after Thursday's 38-31 loss. "It's all depending on how he pushes off." Murray suffered the injury Oct. 14 at Baltimore and has been on the practice field only three times since, and that was just for rehab. He said prior to the Cleveland game there would be a chance he would see action soon, but didn't. The hope is that he will return Dec. 2 against Philadelphia, but coach Jason Garrett made reference to Murray’s "slow progress" Wednesday.
