Coming off their win over the 49ers, the Colts stayed at home for a Week 9 AFC South duel with the Houston Texans.  Indianapolis would get off to a fast start in the first quarter as quarterback Peyton Manning completed a seven-yard touchdown pass to running back Joseph Addai, followed by kicker Matt Stover nailing a 22-yard field goal.  The Colts would add onto their lead in the second quarter as Stover booted a 37-yard field goal, while the Texans would close out the half with a 56-yard field goal from kicker Kris Brown. In the third quarter, Houston began to rally as quarterback Matt Schaub found running back Ryan Moats on a one-yard touchdown pass.  The Texans would take the lead in the fourth quarter with a one-yard touchdown run from running back Steve Slaton, yet Indianapolis regained the lead with Addai's two-yard touchdown run. The Texans attempted to force the game into overtime with a 42-yard field goal attempt, which went wide left. With the win, the Colts improved to 8-0 for the third time in five seasons as well as increasing their winning streak to 16 games. Peyton Manning (34/50 for 318 yards, 1 TD, 1 INT) would become the first quarterback in NFL history to throw for 40,000 yards in one decade. Jim Caldwell would become the first rookie head coach to start 8-0 since Potsy Clark in 1931.
