context:  With the Monday night game having been moved to the University of Minnesota's TCF Bank Stadium due to the snow-induced collapse of the Metrodome roof, Chicago looked to rebound from the previous week's rout in the first outdoor NFL game held in Minnesota in over two decades.  Quarterback Brett Favre made a surprise start for the Vikings after having been ruled out earlier in the week due to injury. Minnesota started strong with an impressive opening drive that culminated in a touchdown pass from Favre to Percy Harvin, but the Bears soon took control in all three phases as the Vikings would be outscored 40-7 over the rest of the game. Jay Cutler connected with Johnny Knox, Devin Hester, and Rashied Davis for three touchdown passes, and Robbie Gould was 4-for-4 on field goal attempts.  Chicago wide receiver/kick returner Devin Hester ran his way into the record books in the third quarter, scoring a touchdown on a punt return off the foot of the Vikings' Chris Kluwe and becoming the all-time NFL leader in combined punt and kick returns for touchdowns. Minnesota quarterback Joe Webb (who entered the game in the second quarter after Favre was injured while being sacked by Bears rookie Corey Wootton) scrambled for a touchdown in the third quarter. With the win, Chicago improved to 10-4 and clinched the NFC North division title.
