Cowboys running back DeMarco Murray sprained a ligament in his left knee on Sunday night.
Murray, who had a 4-yard TD run on the opening drive of the game, never returned after the second quarter.
Owner Jerry Jones said after the game, "We thought DeMarco would be back out there but decided against it."
Fantasy Impact:
Jones also added that he didn't know how to comment on the injury in terms of availability for next week's divisional showdown against the Eagles, "but what I heard doesn't seem long-term..." Murray's status is up in the air for now, in what would be a pretty good matchup against the Birds for first place.
