Cowboys work out several players Tuesday

IRVING -- Tuesday was a busy day at Valley Ranch as the Dallas Cowboys worked out several free agents.

The team didn't sign anyone but the most accomplished of the players is guard/center Nick Cole.

He's started 29 games for the Philadelphia Eagles but was left on the free-agent market after allowing four sacks in 2010. Cole has also worked out for the Detroit Lions.

Tackle Langston Walker, cornerback C.J. Wilson, safeties Chris Horton, Darcel McBath and C.C. Brown, running backs Aaron Brown and Jalen Parmele worked out as well.

The Cowboys have some issues to deal with regarding their roster, especially along the offensive line.

Guards from starter Kyle Kosier (left foot) to backup Derrick Dockery (leg) are recovering from injuries. Kosier is playing through his injury, while Dockery hopes to return to the active roster this week.
