Hoping to save their season, the Titans flew to Jacksonville Municipal Stadium for a Week 4 AFC South duel with the Jacksonville Jaguars.  Tennessee would trail early in the first quarter as Jaguars kicker Josh Scobee got a 22-yard field goal, followed by running back Maurice Jones-Drew's 9-yard touchdown.  The Titans would get in the game in the second quarter with kicker Rob Bironas making a 29-yard field goal.  However, Jacksonville came right back with quarterback David Garrard completing 9-yard and 15-yard touchdown passes to wide receiver Mike Sims-Walker, with Scobee's 50-yard field goal in between. The Jaguars would continue to build their lead as Scobee nailed a 33-yard field goal.  Tennessee would then begin its comeback attempt with quarterback Kerry Collins completing a 14-yard touchdown pass to wide receiver Nate Washington (with a failed 2-point conversion).  The Titans kept their rally going in the fourth quarter with Collins getting a 10-yard touchdown run, followed by running back Chris Johnson's 2-point conversion run.  However, Jacksonville would pull away with Garrard's 33-yard touchdown pass to tight end Marcedes Lewis.
