Starter Dexter Jackson was inactive for the game due to injury. Hoping to rebound from their divisional road loss to the Ravens, the Bengals played their Week 2 home opener against the Tennessee Titans. At the beginning of the game the winds were marked at 20mph and picked up intensity as the game continued, with gusts to hurricane force at times due to the passage of the remnants of Hurricane Ike. After a scoreless first quarter, Cincinnati trailed as Titans RB LenDale White got a 1-yard TD run. The Bengals would respond with RB Chris Perry getting his first career TD on a 13-yard run. However, Tennessee would begin its domination with QB Kerry Collins completing an 11-yard TD pass to WR Justin Gage. In the third quarter, Cincinnati continued to struggle as kicker Rob Bironas nailed a 34-yard field goal. In the fourth quarter, the Titans sealed the win with LB Keith Bulluck blocking and recovering a punt within Cincy's endzone for a touchdown. During the game, the wind was such a factor that it aided the Titan's punter who, with a quick 1-step drop, kicked a punt travelling 70 yards past scrimmage before hitting the ground. It appeared to contribute to difficulties with short passes and long snaps.
