Elliott was unable to finish Tuesday's practice and had his leg stretched out in the middle of the workout. Jones did not have a definitive timetable as to when Elliott would return. But a team source told ESPN's Ed Werder that Elliott will probably miss about a week.
With Elliott and Darren McFadden out, Alfred Morris would move into the first-team role. The Cowboys signed him to a two-year deal in the offseason as a free agent after a four-year run with the Washington Redskins in which he posted three 1,000-yard seasons. Jones said the Cowboys are not on the lookout for a running back, despite the injuries to Elliott; McFadden, who is on the non-football injury list; and Lance Dunbar, who is on the physically unable to perform list recovering from a knee injury, the story said.
