One of the most impressive aspects of the Cowboys' offense during their 31-29 loss to the Ravens was the ease with which running backs DeMarco Murray and Felix Jones cut through the Baltimore defense, combining for 185 yards and a touchdown on 32 carries. But Murray had to leave the game with a foot injury, and now CBS Sports' Jason La Canfora reports that he sustained an apparent foot sprain. According to La Canfora, the X-rays were negative and an MRI is scheduled for Monday to assess the severity of the injury. On the day, Murray gained 93 yards on 14 carries. Source: CBS Sports
