Cowboys starting running back Felix Jones played most of the game against the 49ers with a separated shoulder, owner Jerry Jones said.
Jerry Jones said Felix Jones separated his shoulder on one of his first carries of the game in the first quarter. Felix Jones' last carry of the game was a 4-yard run early in the fourth quarter.
Jerry Jones said he's not sure if Felix Jones will be able to play in the Cowboys' home opener against Washington next week.
DeMarco Murray and Tashard Choice will most likely split up work if Felix can't play. Choice had five carries for five while Murray carried six times for 21 yards. Choice caught two balls for 24 yards.
