As expected, Calvin Johnson is inactive for today's game with a lower back bruise. Also out for the Lions are starting guard Damien Woody (bruised ribs) and defensive end Kalimba Edwards, who'll miss his second straight game with a sprained ankle. Jeff Backus should make his 100th straight start at left tackle.

The Bears aren't any healthier. They'll be without their entire starting secondary — Charles Tillman, Nathan Vasher and Adam Archuleta are inactive, and Mike Brown is on IR — plus linebacker Lance Briggs. Defensive tackle Tommie Harris is expected to play.
