Greg McCoy, a seventh-round pick, was informed of his release, according to a league source.
McCoy had an uphill battle to make the roster, although he played well in the preseason finale.
The Bears have a lot of experience ahead of him, with Charles Tillman, D.J. Moore, Tim Jennings and Kelvin Hayden. The Bears may have kept one fewer cornerback because of the injuries at the safety position.
