Rob Phillips of dallascowboys.com reports that Cowboys' rookie running back DeMarco Murray has a right ankle fracture and a high ankle sprain.
Philips also speculates that the Cowboys could be looking to sign a couple of running backs after tonight's game. Murray's injury is severe enough that he could be headed for injured reserve and Felix Jones is the only other running back active for Sunday's game against the New York Giants.
