The Bears made a move to give themselves some depth on special teams by signing linebacker Gilbert Gardner to the roster Friday.
Gardner, who won a Super Bowl XLI ring with the Indianapolis Colts, and finished second in special teams tackles with Tennessee last season. Gardner appeared in two games with Detroit this season before being released Oct. 25.
To make room for the former third-round pick out of Purdue, running back Garrett Wolfe was placed on injured reserve. Wolfe pulled his hamstring on the opening kickoff of last Sunday's game with Jacksonville.
