The Dallas Cowboys have released defensive end Everette Brown, who played in seven games last season.
They also cut defensive tackle Corvey Irvin, offensive guard Ray Dominguez and offensive guard Jeff Olson.
Brown finished the season with seven tackles, two for losses and four pressures.
He had a sack and forced fumble against the Minneosta Vikings.
The Cowboys have salary-cap issues and may have to consider whether they can afford defensive end DeMarcus Ware and wide receiver Miles Austin.
Their top free agent is defensive tackle Jason Hatcher.
