Answer based on context:

The Titans stayed in 1st place thanks to the extremely strong wind from the remnants of Hurricane Ike (which interfered with an important field goal attempt by Shayne Graham) and a sloppy Cincinnati offense in a 24-7 rout. Chris Johnson ran for over 100 yards for the first time in his career and Kerry Collins had a good day filling in for the injured Vince Young. The Titans first scored on a 1-yd TD run by LenDale White after a scoreless 1st quarter and then Cincinnati scored its only touchdown with a Chris Perry 13-yd TD run on 4th down. The Titans, with a little over a minute left, drove the ball downfield and took a 14-7 lead at the half thanks to an 11-yd touchdown reception by Justin Gage. The knockout punch was delivered early in the 4th quarter with the Titans leading 17-7. Keith Bulluck recovered a blocked punt in the endzone to finish off the Bengals and keep the Titans perfect. The win also gave the Titans their first 2-0 start for the first time since 1999.

Who scored the last touchdown of the game?
Keith Bulluck
