Andrew Luck has one more chance to get things right before the games count.
The rookie quarterback has looked good in the Colts' first three preseason games, though Saturday afternoon's loss at Washington was clearly the toughest.
Against the Redskins, Luck had to contend with a bevy of blitzes, breakdowns along the offensive line and penalties that led to stalled drives.
Unless the Colts can fix those problems, Luck will likely face similar obstacles when he makes his NFL debut Sept. 9 at Chicago.
Coach Chuck Pagano says he hasn't yet determined how much Luck will play in Thursday night's preseason finale against the Bengals.
But Luck knows that this final dress rehearsal for the new-look Colts will be a key game.
