For their annual Thanksgiving Day game, the Lions hosted their NFC North Division rivals, the then-undefeated Green Bay Packers. After a scoreless first quarter, Detroit trailed in the second quarter after Packers quarterback Aaron Rodgers completed a 3-yard touchdown pass to wide receiver Greg Jennings. After halftime, Green Bay added to their lead in the third quarter when fullback John Kuhn scored with a 1-yard touchdown run, followed by a 65-yard touchdown catch to wide receiver James Jones. Later, Mason Crosby scored with a 35-yard field goal. Detroit finally get on the board in the fourth quarter with a 16-yard touchdown run from running back Keiland Williams (with a successful two-point conversion pass from quarterback Matthew Stafford to wide receiver Titus Young), but the Packers pulled away when Crosby booted a 32-yard field goal. The Lions closed out the game when Stafford hooked up with wide receiver Calvin Johnson on a 3-yard touchdown pass late in the final quarter.
