The Colts (4-3) have beaten Tennessee in seven of eight overall and seven of the past 10 in Nashville.
The Colts did it with Luck leading a pair of 80-yard touchdown drives. The top pick overall in April’s draft set up Delone Carter’s 1-yard TD run that tied it up at 13 with 3:24 left in the fourth quarter.
In overtime, Ballard capped the drive, taking a screen pass and going up the left side where he jumped toward the goal line for the TD.
The Titans (3-5) ended a two-game winning streak.
