In the first quarter the Chiefs took the early lead with QB Matt Cassel getting a 2-yard TD pass to OLB Mike Vrabel. The Texans responded and tied the game with QB Matt Schaub making a 5-yard TD pass to TE Joel Dreessen. The Chiefs rallied with Cassel making a 17 and then a 42-yard TD pass to WR Dwayne Bowe in the 3rd quarter. The Texans replied with RB Derrick Ward getting a 38-yard TD run. Then kicker Ryan Succop made a 24-yard field goal to put the Chiefs up 24-14. In the fourth quarter the Texans closed the gap with RB Arian Foster making a 2-yard TD run, but the Chiefs tried to pull away with RB Thomas Jones getting an 11-yard TD run. However, the Texans replied and eventually snatched the win with Foster making a 1-yard TD run, and then with Schaub finding WR Andre Johnson on an 11-yard TD pass. With the win, Houston went into their bye week at 4-2.
