With their MNF home win over the Jaguars fresh in their minds, the Texans flew to Lambeau Field for a Week 14 interconference duel with the Green Bay Packers.  Houston shot early in the first quarter as QB Matt Schaub completed a 58-yard TD pass to wide receiver Kevin Walter.  The Packers would respond in the second quarter with QB Aaron Rodgers completing a 20-yard touchdown pass to TE Donald Lee, yet the Texans would close out the half with a 30-yard field goal from kicker Kris Brown. Houston would get the third quarter's only points as Brown got a 41-yard field goal.  Green Bay would answer in the fourth quarter as RB Ryan Grant got a 6-yard touchdown run, yet the Texans replied with Schaub completing an 11-yard touchdown pass and a 2-point conversion pass to wide receiver Andre Johnson.  The Packers would tie the game as Rodgers completed a 9-yard touchdown pass to wide receiver Jordy Nelson.  Fortunately, Houston got the last laugh as Brown nailed the game-winning 40-yard field goal.
