Green Bay go into the new season looking to bounce back from their embarrassing exit from the playoffs last time around.
The Packers went 9-7-1 during the regular season, but that was enough to earn them a Wild Card place and a trip to face division rivals Chicago.
They blew a late lead when visiting the Bears during the regular season, and this time they suffered an even bigger collapse as they blew a 21-3 half-time lead.
Green Bay held a 21-6 lead heading into the fourth quarter, but inexplicably gave up 25 points as they crashed to a 31-27 defeat.
The Packers warmed up for the new season by going 2-1 in the pre-season, rebounding from a 28-9 defeat in Pittsburgh with wins at Denver, 33-13, and at home to Arizona, 42-38.
