The Packers fell behind Detroit 14-0, but regained momentum when defensive lineman Mike Daniels returned a Lions fumble 43 yards for a touchdown, helping to put the Packers down only 14-10 at halftime. On their opening drive of the second half, Aaron Rodgers gave the Packers the lead for the first time with a 27-yard touchdown run. The Lions would tie the game 17-17 on a Jason Hanson field goal, and after both the Packers and the Lions would both miss field goals, the Packers finally got the lead for good on a 14-yard touchdown run by rookie DuJuan Harris. A Mason Crosby field goal gave the Packers a sure 27-17 lead with just over 4 minutes left in the game. The Lions would kick a field goal with 7 seconds left, but failed the onside kick attempt, giving the Packers a 27-20 win and eliminating the Lions from playoff contention. With a win against the rival Bears the following week, the Packers can clinch the NFC North division.
