Coming off their divisional home win over the Lions, the Vikings flew to Soldier Field for a Week 7 NFC North duel with the Chicago Bears. In the first quarter, the Vikes drew first blood as RB Adrian Peterson got a 1-yard TD run. The Bears would respond with QB Kyle Orton completing an 18-yard TD pass to TE Greg Olsen, along with RB Garrett Wolfe returning a blocked punt 17&#160;yards for a touchdown. Minnesota would respond with QB Gus Frerotte completing a 24-yard TD pass to TE Visanthe Shiancoe. In the second quarter, it would be back and forth. Chicago kicker Robbie Gould would get a 26-yard field goal, while Vikings kicker Ryan Longwell got a 42-yard field goal. Bears CB Zack Bowman would recover a fumble in Minnesota's endzone for a touchdown, while Vikings RB Chester Taylor got a 1-yard TD run. Chicago would close out the half as Gould got a 48-yard field goal. In the third quarter, the Bears got the lead again as WR Rashied Davis recovered a fumble within Minnesota's endzone for a touchdown. The Vikes would reply as Peterson got a 54-yard TD run. Chicago would then strike again as Orton completed a 51-yard TD pass to WR Marty Booker. In the fourth quarter, the Bears struck again as RB Matt Forte got a 1-yard TD run. Minnesota tried to rally as Longwell nailed a 23-yard field goal, along with Frerotte completing a 5-yard TD pass to WR Bernard Berrian. However, Chicago's defense stepped up and prevented the Vikes from tying the game. With the loss, the Vikings went into their bye week at 3-4. The 89 combined points became the highest single-game scoring total in the history of the Vikes/Bears rivalry.
