Coming off their road win over the Steelers, the Colts went home for a Week 11 AFC South rematch with the Houston Texans. In the first quarter, Indianapolis trailed early as Texans kicker Kris Brown got a 28-yard field goal. The Colts responded with kicker Adam Vinatieri getting a 40-yard field goal. Houston would answer with Brown making a 34-yard field goal. In the second quarter, Indy tied the game as Vinatieri got a 39-yard field goal. The Texans retook the lead as RB Ahman Green got a 1-yard TD run. Indianapolis closed out the half as Vinatieri made a 32-yard field goal. In the third quarter, the Colts took the lead as QB Peyton Manning completed a 23-yard TD pass to RB Joseph Addai. Houston would reply as RB Steve Slaton got a 71-yard TD run, yet Indy regained the lead as Addai got a 7-yard TD run. In the fourth quarter, the Texans tried to come back as Green got a 2-yard field goal, yet Indianapolis pulled away with Vinatieri nailing a 31-yard field goal. On the Texans' final drive, QB Sage Rosenfels was intercepted by safety Melvin Bullitt (who was filling in again for the injured Bob Sanders). Ironically, it was Bullitt who picked off Rosenfels on the Texans' final drive when they played the Colts in Week 5. Manning then took a knee, preserving the Colts' third consecutive victory.
