Coming off their bye week, the Texans were at home for a Week 11 interconference duel with the New Orleans Saints.  In the first quarter, Houston trailed early as Saints kicker Olindo Mare completed a 52-yard field goal.  Fortunately, the Texans responded with QB Matt Schaub completing a 73-yard TD pass to WR Andre Johnson.  In the second quarter, New Orleans regained the lead with QB Drew Brees completing a 6-yard TD pass to WR Devery Henderson.  Fortunately, Houston would reply with Schaub completing a 10-yard TD pass to TE Joel Dreesen, along with kicker Kris Brown getting a 36-yard field goal. After a scoreless third quarter, the Texans took control in the fourth quarter as Brown nailed a 53-yard and a 23-yard field goal. With the win, the Texans (for the first time in franchise history) improved to 5-5. Andre Johnson, in his first game back from injuries, had an impressive day with 6 receptions for 120 yards and 1 touchdown. DE Mario Williams had a big game, as he had 6 tackles, a sack, and a forced fumble.
