Quarterback Kirk Cousins threw a late interception as the Washington Redskins blew their chance at a playoff place with a 19-10 NFL home loss to the New York Giants.
Facing a team with nothing to play for, the Redskins were their own worst enemy in a listless performance.
Cousins was twice picked off by Dominique Rodgers-Cromartie in the second half, with the second coming with less than 90 seconds left and the Redskins trailing 13-10.
After New York punted, Washington got the ball back one final time with six seconds left, but as they tried for a miracle play Jordan Reed's attempted lateral pass was picked off by Trevin Wade who ran it in for another touchdown.
The Redskins would have made the playoffs with a win provided the late game between the Green Bay Packers and Detroit Lions did not end in a tie, but they instead face an off-season of questions and recriminations.
Meanwhile, the Giants will advance as the first wild card in the NFC.
