Trying to snap a two-game losing streak, the Packers went home for a Week 10 duel with the Dallas Cowboys.  Green Bay would get the only points of the first half in the form of a 48-yard field goal from kicker Mason Crosby.  After a scoreless third quarter, the Packers would take a huge lead in the fourth quarter with quarterback Aaron Rodgers' 1-yard touchdown run and his 2-yard touchdown pass to tight end Spencer Havner.  The Cowboys would try to rally with quarterback Tony Romo's 9-yard touchdown pass to wide receiver Roy Williams, Green Bay's defense would hold strong for a huge victory. With the win, not only do the Packers improved to 5-4, but also the Packers finally beat Dallas for revenge after 5 years of losing since their meeting with the Cowboys in 2004.
