The Cowboys are working out four players on Tuesday, the team's usual day off.
Among the four include veteran center/guard Nick Cole, who has 29 career starts, with the Eagles. The Cowboys are also working out offensive lineman Langston Walker, a nine-year veteran who has had two stints with the Raiders and also played for the Bills.
Safeties C.C. Brown and Chris Horton also worked out Tuesday, in front of coaches, scouts and front-office personnel. Brown has played for the Texans, Giants and Lions, while Horton spent three years with the Redskins.
The Cowboys typically use Tuesday to work out players, similar to last week when the club worked out Montrae Holland, Daniel Loper and Mansfield Wrotto and signed Holland and Loper to the roster.
Obviously all four of Tuesday's workouts this week appear to be for backup and special teams help.
