Write a question about the following article: The Saints began their 2011 campaign at Lambeau Field, taking on the defending Super Bowl champion Green Bay Packers in the annual NFL Kickoff Game. New Orleans trailed early in the first quarter as Packers QB Aaron Rodgers completed a 7-yard touchdown pass to wide receiver Greg Jennings. The Saints answered with quarterback Drew Brees finding wide receiver Robert Meachem on a 31-yard touchdown pass, but Green Bay struck back with Rodgers completing a 32-yard touchdown pass to wide receiver Randall Cobb. New Orleans clawed their way back into the game in the second quarter with a 30-yard field goal from kicker John Kasay, followed by running back Darren Sproles returning a punt 72 yards for a touchdown. However, the Packers came right back with running back James Starks getting a 17-yard touchdown run. The Saints led off the third quarter with Kasay's 38-yard field goal, but Green Bay replied with Cobb returning a kickoff 108 yards for a touchdown. Afterwards, New Orleans kept fighting as Brees connected with wide receiver Devery Henderson on a 29-yard touchdown pass. In the fourth quarter, the Packers replied with fullback John Kuhn getting a 1-yard touchdown run. New Orleans tried to rally as Brees found tight end Jimmy Graham on a 5-yard touchdown pass, but Green Bay's defense held stuffing a potentially game tying Ingram run on the 1-yard line on the last play of the game to preserve the win.
