In the second quarter, the Buccaneers got on the board with RB Earnest Graham getting a 4-yard TD run.  Afterwards, Houston answered with Rosenfels completing an 8-yard TD pass to WR Kevin Walter. In the third quarter, the Texans immediately increased their lead as WR Andr&#233; Davis returned the half's opening kickoff 97 yards for a touchdown.  Tampa Bay would respond with Graham getting an 11-yard TD run.  In the fourth quarter, Houston ended the game with Rosenfels completing a 4-yard TD passe to TE Owen Daniels.
