The depleted Bears' special teams unit just took a big hit.
Garrett Wolfe, the leading tackler, has been ruled out of the game with a hamstring injury.
Wolfe leads the team with 21 special teams tackles and far and away has been the most consistent performer for special teams coordinator Dave Toub.
Wolfe was injured on the game's opening kickoff.
The Bears have been seeking special teams help but have not found anyone out on the street to take the roster spot of defensive tackle Dusty Dvoracek.
