Cowboys release reserve CB Oglesby

Posted by ESPN.com's Matt Mosley

The Dallas Cowboys just released cornerback Evan Oglesby. Second-year cornerback Alan Ball and Oglesby had battled throughout training camp for the final spot at cornerback. This clears a spot for safety Keith Davis, who was released by the Dolphins last week.

The Cowboys will also need to clear a spot for quarterback Brooks Bollinger after the Browns game.
