SEATTLE -- It was a defeat that will leave the Seahawks kicking themselves.
And in large part because they simply couldn't kick it when they needed to.
Three missed field goals by Blair Walsh in the first half opened the door for Washington to pull the upset.
And a late 70-yard touchdown drive then allowed Washington to kick it open with Rob Kelley's 1-yard score with 59 seconds left giving the visitors a stunning 17-14 victory.
Seattle seemed poised to win it when Russell Wilson hit Doug Baldwin on a 34-yard touchdown with 1:34 left to take a 14-10 lead.
But two long completions by Washington quarterback Kirk Cousins led to a shocking Seattle collapse.
First, Cousins hit Brian Quick over Kam Chancellor and Justin Coleman to move Washington to the 39.
Josh Doctson then beat Shaquill Griffin down the left side and dived to catch Cousins' pass, sliding to the 1-yard line with 1:02 left.
The Seahawks used their last time out and after a lengthy review the play was upheld.
Kelley then scored his second touchdown of the game with 59 seconds left and combined with the PAT put Washington ahead 17-14.
