Andrew Luck led Indianapolis back from a 13-point second-half deficit and Adam Vinatieri made two fourth-quarter field goals as the Colts rallied for a 27-23 victory Sunday over the Tennessee Titans.

Luck has now engineered six fourth-quarter comebacks this season for Indy (9-4).

It wasn't all Luck.

Delone Carter cut the deficit to 20-14 with a 1-yard TD run on Indy's opening possession of the second half. And after Pat McAfee's 52-yard punt went out of bounds at the Titans 1-yard line, Cassius Vaughn jumped in front of Nate Washington, picked off Jake Locker's pass and scored on a 3-yard interception return to make it 21-20.

Rob Bironas gave the Titans (4-9) a 23-21 lead with a 25-yard field goal, but VInatieri hit from 53 yards to retake the lead and from 40 to seal it.
