OXNARD, Calif. -- With injuries to four interior offensive linemen, the Cowboys are bringing in familiar faces for a workout.
Holland started 11 games last season at right guard. The team cut him at last year's training camp but re-signed him after Bill Nagy suffered a season-ending ankle injury.
Dockery started two games after joining the team following training camp. Loper was on and off the roster but did not appear in a game.
Nate Livings suffered a hyperextended knee in Wednesday's practice, but he is not expected to be out long. Nagy suffered a high ankle sprain Monday and is not expected to return soon.
