The Packers, after their 26-20 victory over the Dolphins on Christmas Day, are suddenly winners of three consecutive games.
Green Bay's win sets up a Sunday rematch with meaning at Lambeau Field as the Vikings (12-3) try to maintain the NFC's No. 2 seed and the Packers (7-8) fight to keep playoff hopes alive.
"They're playing good football right now," Vikings coach Kevin O'Connell said Monday. "Their defense is getting turnovers. They clearly have one of the best quarterbacks in our game, and they're continuing to get comfortable with their personnel."
The Packers looked cooked at 4-8 following a loss to Philadelphia on Nov.
