The Bears took on the rival Green Bay Packers at Lambeau Field in week seven. The game was the eleventh consecutive primetime game between the two and the sixth in Green Bay, with the Bears winning two of the last three. Entering week seven, the Bears led the all-time series 93-91-6. In the teams' last meetings since the turn of the decade, the Bears had lost all but three games, including the most recent game in 2015, a 17-13 victory in Green Bay. The Bears were struggling to score in 2016, averaging a league-worst 16.8 points per game. As such, Jeff Joniak wrote the Bears needed to score touchdowns, especially considering their struggles in the red zone (on 19 trips to the region, the Bears scored only nine times). Outside of the red zone, the Bears scored only 10 points; in comparison, the NFL average was 37. Chicago's rushing attack faced a Green Bay defense that allowed only eight runs of at least ten yards and 3.4 yards on first down, the third-lowest in the league. On defense, the Bears faced Aaron Rodgers; while the Packers offense was only 26th in yardage and at -3 in turnover ratio, the unit led the league in third down completion percentage. Rodgers also excelled in the first quarter of games, where he had thrown four touchdown passes, good for second in the league, and a 106 passer rating. However, the Packers struggled on drives starting within their own 20-yard line, failing to score on 14 such drives, the only team unable to do so. Joniak also wrote the team needed a "spark"; defeating the Packers at Lambeau for the second straight season would "do wonders for a young team trying to find its way." After the Bears punted on the opening drive, the Packers took the lead first with Mason Crosby's 32-yard field goal. The Bears were forced to punt again on their next series and the Packers reached as far as the Bears' one-yard line before they were stopped on fourth down. On Chicago's resulting drive, Brian Hoyer was hit by Clay Matthews and Julius Peppers while throwing a pass, breaking his left arm. With Jay Cutler also inactive, third-string quarterback Matt Barkley took over for the next possession. With Barkley, the Bears were able to score points via Connor Barth's 39-yard field goal, which the Packers responded with Crosby's 40-yard kick. On Green Bay's first drive of the second half, Leonard Floyd strip-sacked Rodgers, recovering the fumble in the endzone to give the Bears the 10-6 lead. The score marked the Bears' first defensive touchdown since 2014. Rodgers overcame the play by throwing a five-yard touchdown pass to Davante Adams, followed by two more touchdown passes to Adams and Randall Cobb of four and two yards, respectively (though Crosby missed an extra point). Down 26-10, the Bears' next two series ended with interceptions, Barkley being intercepted by Blake Martinez and Nick Perry. The 1-6 start marked the first start with such a record since 2000.
