Not wanting to take only two running backs into Sunday's game, the Cowboys promoted Chauncy Washington back off the practice squad. They released center Duke Preston to make room for Washington.
The Cowboys did the same thing last week, moving Washington up to the 53-player roster Saturday, but got burned when the Lions claimed safety Marvin White. Washington played on special teams against the Broncos, making one tackle. He did not get in at running back as Marion Barber and Tashard Choice carried the load.
Running back Felix Jones (knee) is expected to return after the bye.
Preston's release means the Cowboys are comfortable with Andre Gurode (knee). Gurode said Friday he would start against the Chiefs.
