In need of depth at running back, the Cowboys signed Chauncey Washington off their practice squad and released safety Marvin White.
The Cowboys won’t have Felix Jones for Sunday’s game against the Broncos because of a knee injury, leaving them with Marion Barber and Tashard Choice as their main running backs. Barber is returning from a thigh injury, so if he aggravates it, the Cowboys now can turn to Washington for help.
Washington, a seventh-round draft pick by the Jaguars in 2008, played in six games with Jacksonville last season and had 9 yards on four carries.
White played in 27 games (13 starts) with the Bengals the previous two seasons before being claimed off waivers by the Cowboys last month. He has two tackles in three games (no starts) this season.
