Cowboys release CB Bryan McCann

The Cowboys released cornerback Bryan McCann on Tuesday.

With the team thin at wide receiver, the team will sign Laurent Robinson, who was cut last week after he suffered a hamstring injury. McCann, who played at SMU, didn't play on defense in the Week 2 victory over the San Francisco 49ers because of the addition of Frank Walker, a veteran corner who moved up the depth chart because of injuries.

The expected return of Terence Newman this week from a groin injury and the emergence of Walker made McCann's future with the team in doubt.

As it stands now the Cowboys have only Alan Ball, Walker and Newman as the healthiest corners on the team. Mike Jenkins is still playing with some ailments and Orlando Scandrick is out for about two more weeks with a high ankle sprain.

Meanwhile, the Cowboys have issues at wide receiver.

Miles Austin probably won't play Monday night against the Washington Redskins, and Dez Bryant is still recovering from a thigh bruise. His status for the game is in question.

That leaves Jesse Holley, Kevin Ogletree, Dwayne Harris and now Robinson as the receivers.
