Cowboys plan to promote RB Chauncey Washington

IRVING, Texas -- The Cowboys plan to promote running back Chauncey Washington from the practice squad, according to a source.

The Cowboys need depth at running back with Felix Jones' status uncertain due to tightness in his hamstring. Jones has not practiced this week. Sammy Morris, the 12-year veteran who signed last week, is the only other tailback on the roster.

Washington, 26, who was added to the practice squad on Nov. 30, has nine games of NFL experience, including two with the Cowboys in 2009. He has only four carries for 9 yards in his career, but he could replace Morris on special teams if Morris has to play a larger role on offense.

The Cowboys are still discussing what move they will make to open up a roster spot for Washington.
