The Chicago Bears have been ravaged by injuries, most notably on defense, this season. And there was another massive hit as rookies defensive tackle Shemar Turner is done for the year with a torn ACL, head coach Ben Johnson announced Monday.

The Chicago Bears signed defensive back C.J. Gardner-Johnson on Wednesday, bringing in a veteran to help a secondary severely depleted by injuries.

Coming off a 30-16 loss to the Ravens, the Bears face a major defensive test this weekend against a high-powered Cincinnati Bengals passing attack.
