Dallas fell behind early and lost to the New York Giants by a fingertip, 29-24.
Tony Romo threw for 437 yards and a touchdown but also had four costly interceptions as Dallas fell behind 23-0 in the first half.
The Cowboys rallied and actually took a 24-23 lead in second half and had a chance to win the game. Romo connected with Dez Bryant for an apparent game winning touchdown only to have it ruled out of bounds.
Replays showed Bryant's right fingertip was out of the endzone making the pass incomplete.
Dallas is now 3-4 on the season and will play the undefeated Atlanta Falcons next Sunday night on NBC NewsChannel 9.
