DeMarco Murray is not worried about his recent fumbling issues. "Doesn't bother me at all," Murray said. "Last week was last week. Two weeks was two weeks ago. I don't worry about mistakes." Murray has lost a fumble in back-to-back weeks, and his one last week against the Saints came inside his own five-yard line and led to a New Orleans touchdown. The Cowboys aren't worried, though, either. Murray has played his heaviest snap counts of the season over the last three games as he returns to full health from a foot injury, and back-up Felix Jones has been kicked to the curb.
