context:  Trying to snap a two-game losing streak, the Packers stayed at home for a Week 7 NFC North Sunday night duel with the Minnesota Vikings, as quarterback Brett Favre made his return to Lambeau Field.  Green Bay delivered the opening punch in the first quarter as running back Brandon Jackson got a 1-yard touchdown run.  The Vikings answered with wide receiver Percy Harvin getting a 17-yard touchdown run.  In the second quarter, the Packers regained the lead as quarterback Aaron Rodgers finding tight end Andrew Quarless on a 9-yard touchdown pass.  Minnesota would take the lead with running back Adrian Peterson getting a 1-yard touchdown run, followed by kicker Ryan Longwell making a 28-yard field goal. Green Bay regained the lead in the third quarter as Rodgers hooked up with wide receiver Greg Jennings on a 14-yard touchdown pass, followed by linebacker Desmond Bishop returning an interception 32 yards for a touchdown.  The Vikings answered with Favre completing a 4-yard touchdown pass to wide receiver Randy Moss.  Late in the 4th quarter, Favre led the Vikings to a last-minute drive to near the Packer 20 and nearly had a game-winning touchdown pass, but official review showed the receiver, Percy Harvin, did not have both feet in the end zone, therefore making the pass incomplete. The Vikings tried a game-winning pass on 4th down, but Favre's throw was high to Moss and the Packers held on to their first victory over their former QB.
