NASHVILLE, Tenn. -- This is why the Indianapolis Colts drafted Andrew Luck with the top overall pick in April.
Stymied most of the day by the Tennessee Titans' normally pliable defense, Luck walked off the field Sunday when Vick Ballard took his screen pass 16 yards -- leaping high into the air to crack the goal line's plane with the ball -- with 10:11 left in overtime to finish off a 19-13 win.
Indianapolis (4-3) forced overtime when backup running back Delone Carter leaped 1 yard with 3:24 remaining in regulation, capping a 14-play, 80-yard drive that lasted 7:02. Carter's 7-yard run on fourth-and-1 from the 8 kept the drive going.
Tennessee (3-5) took a 10-3 lead into halftime when rookie wide receiver Kendall Wright made a balletic 23-yard touchdown reception a minute before intermission, gaining separation from Cassius Vaughn and then tapping one foot down while toe-dragging the second one inbounds.
Otherwise, most of the game was an exhibition of the teams constructing promising drives which concluded either in field goals or without points for one reason for another.
The Titans started out with a 13-play, 59-yard march which lasted 7:25, ending in Rob Bironas' 39-yard field goal -- the 200th of his career. Indianapolis answered with a 12-play, 83-yard drive that ate up 6:29, but had to settle for Adam Vinatieri's 20-yard field goal when Luck was tackled from behind at the 2 on a scramble to the end zone.
On their next drive, the Colts kept the ball for more than 5 minutes, but were forced to punt when Donnie Avery committed a crackback block after they reached the Tennessee 33. Indianapolis then maneuvered into field-goal range on its last drive of the half, but Michael Griffin ripped through a badly-executed protection scheme to block Vinatieri's 37-yard attempt.
In the third quarter, the Titans missed on a chance to add to a 10-6 lead when the normally-reliable Bironas missed wide right from 45 yards as the ball was caught in a swirling crosswind.
