Indianapolis tied it at 14 when Luck deftly slid into the end zone on fourth-and-goal from the 1, ending a drive in which Luck completed all five of his passes.
Luck got one more chance just before the half, and he made it count. Working exclusively out of the shotgun, Luck led the Colts 31 yards in five plays, giving Adam Vinatieri just enough time — and room — to sneak a kick between the uprights at the halftime gun.
