The Chicago Bears signed center-guard Rob Turner.
The veteran lineman started six games last season for the Tennessee Titans before going on injured reserve with a shoulder injury.
In 2012, he started every game for the St. Louis Rams.
Turner was added to the roster after center Brian de la Puente sprained his medial collateral ligament.
The Bears cut guard Graham Pocic.
