Harris has suffered from knee injuries in recent years but was not on the injury report this week. That means this is a coaching decision, and a surprising one. Harris has only one tackle in two games this season but has been considered a central part of their nucleus. Third-year player Matt Toeaina will start in his place.
The Bears also deactivated receiver Devin Aromashodu.
Meanwhile, the Packers have left tackle Chad Clifton active and did not announce a change in their starting offense, so we're assuming Clifton will start with Daryn Colledge at left guard. Rookie Bryan Bulaga will probably play in some capacity, however.
