Next came a difficult road battle with the 8-2 Atlanta Falcons, in which the Packers lost a close one 20–17. After routing San Francisco, the Packers headed to Detroit. What looked like an easy win proved anything but when Rodgers was knocked out with a concussion during a quarterback sneak and replaced by Matt Flynn. The latter was unable to get anything going as Green Bay lost a defensive struggle 7–3, falling to the Lions for the first time since 2005. Rodgers was then ruled out for the Week 15 game at New England.
