The Titans got off to a surprising start, as QB Vince Young ran 19 yards for a touchdown.  Tennessee would follow it up in the second quarter, as kicker Rob Bironas kicked a 22-yard field goal to give the Titans a 10-0 halftime lead.  In the third quarter, Tennessee would get an unpleasant wake-up call, as Colts QB Peyton Manning completed a 13-yard TD pass to WR Marvin Harrison.
