Jones had led the Cowboys with 253 yards and one rushing touchdown after five weeks, totals that were equaled in last Sunday's 34-7 win over the St. Louis Rams by 2011 third-round pick DeMarco Murray, who is expected to get the start against the Philadelphia Eagles on Sunday night.
Murray got his chance as Tashard Choice struggled with ball security and injured his shoulder, which along with a hamstring injury, which required an MRI on Friday, has him listed as "Questionable" for Sunday night's game.
Choice could be inactive, which would leave Murray and undrafted rookie Phillip Tanner as the healthy running backs on the roster when they take on an Eagles' run defense that allowed just 42 yards to the Washington Redskins before their bye week, but for the most part has struggled against the run. The Eagles had allowed 140.2 rushing yards per game the first five weeks of the season.
