Answer based on context:

The Vikings began their 2008 campaign on the road against their NFC North foe, the Green Bay Packers, in the first game of 2008's Monday Night Football doubleheader. After a scoreless first quarter, the Vikings attacked first with kicker Ryan Longwell getting a 37-yard field goal. The Packers responded with QB Aaron Rodgers completing a 1-yard TD pass to FB Korey Hall, along with kicker Mason Crosby getting a 42-yard field goal. In the third quarter, the Vikes tried to catch up as Longwell got a 27-yard field goal, but Green Bay replied with CB/PR Will Blackmon returning a punt 76yards for a touchdown. In the fourth quarter, Minnesota tried to rally as QB Tarvaris Jackson completed a 23-yard TD pass to WR Sidney Rice (with a failed 2-point conversion), yet the Packers responded with Rodgers getting a 1-yard TD run. The Vikes would reply with RB Adrian Peterson getting a 3-yard TD run, but their final rally ended in an interception. With the loss, not only did the Vikings begin their season at 0-1, but Head Coach Brad Childress fell to 0-5 against the Packers in his coaching career. In the first half, Minnesota was widely outgained in passing yards 139-6.
