Coming off their home win over the Dolphins, the Texans flew to Jacksonville Municipal Stadium for a Week 6 AFC South showdown with the Jacksonville Jaguars.  In the first quarter, Houston struck first with kicker Kris Brown getting a 20-yard field goal for the only score of the period.  In the second quarter, the Texans increased its lead with Brown kicking a 35-yard field goal.  However, the Jaguars took the lead with QB David Garrard completing a 1-yard TD pass to TE George Wrighster, along with kicker John Carney getting a 37-yard field goal. In the third quarter, Houston continued to trail as Garrard completed a 9-yard TD pass to WR Reggie Williams (with a blocked PAT).  The Texans would respond with Brown getting a 33-yard field goal.  However, in the fourth quarter, Jacksonville would pull away with RB Maurice Jones-Drew getting a 7-yard TD run, LB Daryl Smith returning a fumble 77 yards for a touchdown, and Jones-Drew getting a 57-yard TD run.   Houston's only response would be back-up QB Sage Rosenfels completing a 1-yard TD pass to FB Vonta Leach. So far this year, Houston is 1-3 without WR Andre Johnson, who was still recovering from injuries.
