Owner Jerry Jones confirmed that DeMarco Murray will remain a "workhorse" even though Felix Jones (ankle) is expected back Sunday. It's a no-brainer. Over the last four games, Murray has averaged 150.2 rushing yards per game while breaking off 8.01 yards per carry. "One thing that comes to my mind is that Murray looks like the more he carries, the more effective he gets," Jerry Jones said. The owner went on to hint that Felix could "step in" 12 or 13 times per game, but we'd be surprised if he got that much work. Murray is locked in as the feature back.
