In their home opener, the Falcons hosted the Green Bay Packers in a rematch of the 2016 NFC Championship Game. This was the first regular season game at Mercedes-Benz Stadium. Despite prior reports that the roof would be closed for the game, Falcons owner Arthur Blank elected to open the roof if weather permitted, marking the first time since the 1991 season, the team's final season at their original home of Atlanta-Fulton County Stadium, that the Falcons played a home game in Atlanta under open air. The Falcons controlled most of the game, went up by as much as 24, and won 34-23. They were led by Devonta Freeman (19 rushes, 84 yards, 2 TD) and Julio Jones (108 yards, 5 receptions). The 2017 Falcons became only the fourth team in NFL history to start 2-0 after they lost the Super Bowl the previous year.
