With only four days between games, Teddy Bridgewater had insufficient time to recover from the injury he picked up in week 4 and Christian Ponder made his first start since week 12 of the 2013 season. The Vikings defense forced Green Bay to punt on the first possession of the game, but soon kicked the ball back to the Packers, allowing Eddie Lacy's running to set up an 8-yard touchdown pass from Aaron Rodgers to Randall Cobb. The Vikings' ensuing possession again ended with a punt, and Rodgers punished them with a 66-yard TD pass to Jordy Nelson. The teams traded possession as the game moved into the second quarter, until Ponder threw the ball directly to Packers DE Julius Peppers, who returned the interception 49 yards for his team's third TD of the game. Two plays later, Ponder was picked off again, this time by LB Jamari Lattimore, leaving a short field for Rodgers to work into before throwing an 11-yard TD pass to WR Davante Adams. The second half began in much the same vein, as the Packers forced a Vikings punt on the first possession before marching downfield to set Lacy up for an 11-yard scoring run. The running back went into the end zone again at the end of the Packers' next possession with a 10-yard run, giving the home team a 42-0 lead. CB Marcus Sherels returned the ensuing kickoff 46 yards, and Ponder was able to pass downfield to the Green Bay 6-yard line, from where he ran into the end zone for the Vikings' first points of the game. Three plays later, Harrison Smith picked off a pass from Matt Flynn at the Green Bay 30-yard line, but the Vikings were unable to get into the end zone despite the short field and had to settle for a 26-yard Blair Walsh field goal. As the game drew to a close, the Vikings regained possession and drove down to the Packers' 8-yard line, only to be denied on 4th-and-goal, allowing Green Bay to end the game with a kneeldown.
