Houston quarterback Matt Schaub hit Owen Daniels from 39 yards out for the game's only touchdown with time running out in the opening 15 minutes to cap a four-play, 77-yard drive.
Schaub finished the half 8-of-14 for 124 yards. His Buffalo counterpart, Brian Fitzpatrick, was 14-for-17 for 144 yards.
Buffalo got its six points off a pair of field goals from Rian Lindell in the final two minutes of the half. The second field goal, with just five seconds left, came after Fitzpatrick was sacked for a loss of six yards nearing the endzone. The Bills instead had to settle for three points off a 38-yard kick from Lindell.
With such a low-scoring game, this hasn't been one to fill the box score, but Arian Foster leads both teams with 62 yards rushing on seven carries. Fred Jackson has 19 yards on the ground to lead the Bills.
