Context: Down four games, the Titans went home for a Week 5 Sunday night duel with their AFC South rival, the Indianapolis Colts.  Tennessee would trail in the first quarter as Colts quarterback Peyton Manning found wide receiver Reggie Wayne on a 3-yard touchdown pass.  The Titans would answer with a 49-yard and a 43-yard field goal from kicker Rob Bironas, but Indianapolis came right back in the second quarter with running back Joseph Addai's 1-yard touchdown run.  Tennessee tried to keep it close with Bironas nailing a 46-yard field goal, yet the Colts continued its domination with Manning hooking up with wide receiver Austin Collie on a 39-yard touchdown pass.  Afterwards, Indianapolis would pull away in the second half.  Manning connected with Collie again on a 6-yard touchdown pass, followed by kicker Adam Vinatieri booting a 23-yard field goal.
