Cowboys RB options limited for Philly

IRVING, Texas -- Dallas Cowboys head coach Jason Garrett might not have to make a decision on who will start at tailback Sunday at Philadelphia after all.

As expected, Felix Jones will miss his second straight game with an ankle injury and Tashard Choice is questionable with shoulder and hamstring injuries, which would leave the job to DeMarco Murray. The rookie ran for a franchise record 253 yards last week against the St. Louis Rams.

Jones could miss another two games with a high left ankle sprain suffered Oct. 16 at New England. Choice suffered his shoulder injury in the third quarter against the Rams and was limited in practice Wednesday and Thursday before tightness in his hamstring kept him out of Friday's workout altogether.

If Choice, who had an MRI on Friday, cannot play, then the Cowboys would have only two tailbacks active for a game for the first time since the end of the 2008 season.

Murray and fellow rookie Phillip Tanner are the healthiest tailbacks on the 53-man roster, and the Cowboys do not have a running back on the practice squad.

Murray will look to back up his record-setting performance against the Philadelphia Eagles' 23rd-ranked run defense. The Eagles have allowed five running backs to gain at least 85 yards on the ground this season and three -- Atlanta's Michael Turner (114), San Francisco's Frank Gore (127) and Buffalo's Fred Jackson (111) -- to eclipse 100.

Murray's 253 yards came on 25 carries and included a 91-yard touchdown run on his first carry, which was the second-longest rush in team history.

Garrett was pleased with how the third-round pick has handled the newfound attention after carrying it just 24 times for 71 yards in the first five games of the season.

"That's the way he's been since we got him, that was the reputation he had out of school," Garrett said. "He had a lot of success at Oklahoma and he just seems to be a very even-keeled guy, works hard every day, wants to learn and wants to get better and this week has been no different for him."
