Luck was brilliant, going 21 of 36 for 252 yards. He broke a 17-17 tie with a TD pass early in the fourth quarter, then helped snap a 24-24 tie by setting up Vinatieri for the field goal on the next drive. Indy ran out the final 5:57.
Manning was 21 of 36 for 281 yards with two TDs and two interceptions. He couldn't break Brett Favre's record for regular-season wins (186) by a quarterback and fell 3 yards short of becoming the NFL's career passing leader.
