The Dallas Cowboys have released four players, including a pair of defensive linemen added last season to shore up the injury-riddled position.
Everette Brown and Corvey Irvin played backup roles after signing during the season. Brown had seven tackles and a sack in seven games at defensive end. Irvin had five tackles in six games at defensive tackle.
The Cowboys also dumped guards Ray Dominguez and Jeff Olson. Neither played last season.
