Andrew Luck led the Indianapolis Colts to overtime against the undefeated Carolina Panthers on Monday night after playing poorly through the first three-plus quarters, but an interception set up Carolina's game-winning field goal.

He threw three interceptions in the game, bringing his total to 12 for the season. Luck threw just 16 picks all of last season and had just nine in 2013.

"It's my problem and it's hurting the team," Luck told the Indianapolis Star. "And I've got to fix it or else it's tough to win doing it. Disappointed in myself. ... It's hard to find perspective right now. We lost. At the end of the day, that's what matters. We did some decent things to give ourselves a chance, but messed it up at the end by throwing an interception."

When asked about a report that he has been playing with broken ribs, Luck said he wasn't "going to get into that right now."
