The Green Bay Packers' defense that has had difficulty stopping the run all season just took a significant hit with news linebacker Nick Barnett will miss the remainder of the season with a torn knee ligament.
Minnesota's Adrian Peterson rolled for 192 yards in the Vikings' 28-27 victory over the Packers Sunday at the Metrodome.
Barnett, who leads Green Bay in tackles, is one of the best defensive players in the division. Packers coach Mike McCarthy said he does not have a clear replacement in mind.
The Bears rushed for 136 yards in their victory over Green Bay at Soldier Field last season.
