Ed Werder of ESPN suggests that Cowboys running back Darren McFadden is a candidate to replace Lance Dunbar (who is now on IR) as the preferred backfield option in passing situations.
While that doesn't change the fact that Joseph Randle will remain the primary ball carrier, Dunbar did manage 21 catches for 215 yards in four games prior to suffering his season-ending injury. So if McFadden does end up absorbing some added work as a pass-catcher, it could result in a degree of added Fantasy value for him, notably in PPR formats.
