Lovie Smith's Chicago Bears return home to Soldier Field, where they'll play host to Jeff Fisher and the 1-1 St. Louis Rams. The Rams managed to pull off a mild upset in Week 2, defeating the Washington Redskins, so they might be able to do the same in Chicago.
Clearly, If the Vikings want to keep a claim of first place, they'll need to make sure they take care of business against a tough foe in the 49ers this weekend.
