INDIANAPOLIS -- Indianapolis Colts quarterback Andrew Luck had been a vanishing act for the first 11 quarters of the NFL season.

His accuracy -- to his receivers at least -- had been off the mark. Luck had no problem throwing the ball to the other team or fumbling it away to the tune of eight turnovers in those 11 quarters. The eight turnovers are more than 29 other teams have this season.

Everybody wondered: What's wrong with Andrew Luck?

Then, with the season on the brink of officially becoming a disaster, the Luck that so many gravitated to because of his ability to battle through adversity showed up during the fourth quarter of Sunday's game against the Tennessee Titans.

A 98-yard drive and two touchdown passes -- including one in which Luck called an audible and threw an 11-yard touchdown to receiver Donte Moncrief -- came just 59 seconds apart. Just what Luck, and more importantly, the Colts needed in their victory of the season.

"Maybe settled down a bit and just played football," Luck said. "It's hard to explain. We've been here before. I've tried to explain my interceptions are stupid plays. You get tired of talking about it and at some point just got to change that. So I think maybe that clicked and then just went out and said, ‘Alright.'"

Luck has mental toughness. He has to have it when you take into consideration his ability to forget about his turnover problems. Too often Luck has jogged back to the sideline smacking himself on top of his helmet in frustration.

"Saying some four-letter words to myself that I don't want to repeat," Luck said.

The coaching staff doesn't say much when Luck makes a mistake. His teammates know he'll be fine because as guard Jack Mewhort put it, "He doesn't get rattled."

The offensive line did a better job with its protection, Luck was more decisive with the ball and his receivers were able to create some separation to get open in the fourth quarter. He was 11-of-13 for 144 yards and two touchdowns in the final 15 minutes of the game. He was 7-of-17 for 116 yards and two interceptions during the first three quarters.

"Amnesia," coach Chuck Pagano said. "And you have to be able to do it in the National Football League, especially playing that position. Andrew does a great job of making the corrections once he comes off and then moving forward."

The Colts don't want Luck to forget the fourth quarter of Sunday's game. They want that to be the start of Andrew Luck being Andrew Luck again.
