Coming off their easy win over the Seahawks, the Vikings stayed at home, donned their throwback uniforms, and faced the Chicago Bears in a Week 12 duel. After a scoreless first quarter, the Vikings drew first blood as quarterback Brett Favre completed a 15-yard TD pass to rookie wide receiver Percy Harvin. The Bears responded with QB Jay Cutler firing a 24-yard TD pass to WR Johnny Knox. The Vikings responded with Favre hooking up with running back Chester Taylor on a 10-yard TD pass, along with kicker Ryan Longwell nailing a 52-yard field goal. Finally, the Vikings closed out the first half with Favre finding tight end Visanthe Shiancoe on a 6-yard TD pass. In the third quarter, the Bears tried to rally with kicker Robbie Gould nailing a 38-yard field goal. However, the Vikings finally shut out the Bears for the rest of the second half, and kicker Ryan Longwell made field goals of 37 and 20 yards. Running back Adrian Peterson also had a 5-yard TD run (with a missed extra point attempt). With the win, the Vikings improved to 10-1, and compiled a 5-0 record against their NFC North rivals. Their "magic number" decreased to two, meaning that any combination of two Vikings wins or Packers losses would result in the Vikings clinching their second consecutive NFC North division title. On Wednesday December 2, the NFL honored Brett Favre with the NFC Offensive Player of the Month for November. It was the sixth time in his career that he won the award.
