One of five unbeaten teams in the NFL, the surprising Green Bay Packers seek their first 4-0 start in nine years on Sunday when they visit the Minnesota Vikings in an NFC North contest.

In last week's 31-24 victory over the San Diego Chargers, Brett Favre threw three touchdown passes to match Dan Marino's all-time mark of 420.

The ageless quarterback tied the record in dramatic fashion, finding Greg Jennings over the middle for a 57-yard score with 2:30 remaining to give the Packers a 24-21 lead.

It was the 150th career victory for Favre, who a week earlier surpassed John Elway to become the quarterback who has won the most games in NFL history.

A three-time MVP, Favre should break another NFL record this week as he is just 10 passes shy of Marino's mark of 8,358 career attempts.

The Packers have passed 70% of the time and this week should be more of the same as they will be facing the NFL's number one run defence from last season.

"I would prefer to be a heavy run team, but that's just not the way we're built right now, and that's not the way that gives us the best chance to score a lot of points in my opinion," Green Bay coach Mike McCarthy said.

The Vikings return home after suffering a 13-10 loss at Kansas and have issues at quarterback.

Kelly Holcomb replaced Tarvaris Jackson, who was sidelined with a groin injury, and completed just 13 of 26 passes for 160 yards.

Minnesota did get a solid game from rookie running back Adrian Peterson, who rushed for 102 yards and caught three passes for 48 yards.

Peterson is now the Vikings' featured running back, following a Week One hip injury to Chester Taylor.

The Vikings are looking to snap a two-game losing streak and escape the NFC North basement.
