Dallas Cowboys searching for CB depth

OXNARD, Calif. -- The Dallas Cowboys are searching for depth for their depleted cornerback corps.

The team visited with free-agent cornerback Charles Sawyer but will not sign him, a source said.

The Cowboys are currently practicing without four cornerbacks. Starter Brandon Carr isn’t expected to report to camp until the weekend due to the death of his mother. Morris Claiborne, who is competing for the other starting role, has missed the last three practices due to tendinitis in his right knee. Veteran Sterling Moore has been sidelined by a sore groin. Undrafted rookie Dashaun Phillips is out with a strained hamstring.

The Cowboys want to add a corner to give them enough players at the position to practice competitively. They anticipate being thin at corner during Thursday’s preseason opener against the San Diego Chargers.

Seventh-round pick Terrance Mitchell, 2013 fourth-round pick B.W. Webb and undrafted rookie Tyler Patmon should see extensive action against the Chargers, as the Cowboys won’t want to overwork veteran Orlando Scandrick.

“For those young guys, they’ll get a chance to go play and see what they’re made of,” secondary coach Jerome Henderson said.
