LB Lance Briggs, CB Nathan Vasher and DT Darwin Walker are all inactive for today's game.
Also out are DE Mark Anderson, S Josh Gattis, G Josh Beekman and WR Mike Hass. Rex Grossman will serve as the third quarterback.
It will give the Bears a chance to look at Jamar Williams at weak-side linebacker in Briggs' absence. Alex Brown will start in place of Anderson and Trumaine McBride will replace Vasher.
For Green Bay, the only starter missing will be DT Ryan Pickett. First-round pick Justin Harrell will replace him.
