The Vikings will be going for their fifth straight win when they host the Bears on Monday Night Football at the Metrodome.  The Vikings are 7-and-6 and can take a one-game lead for the final NFC playoff spot with a win.  Tarvaris Jackson threw for a score and Chester Taylor rumbled for 101 yards and a TD in Minnesota’s 27-7 drubbing of the San Francisco 49ers in Week 14.  The Vikes are 4-and-2 at home this season while the Bears are just 2-and-4 on the road.  The Bears come in at 5-and-8, but will be mathematically eliminated from playoff contention with a loss.  Chicago has dropped two straight after falling 24-16 in Week 14 to the Washington Redskins.  Quarterback Kyle Orton will make his first start for Chicago since his rookie season in 2005.  The Vikings won the first meeting 34-31 in Week Six in Chicago.
