The Cowboys clicked into gear on their second possession of the first quarter as Tony Romo made several good throws on third down, including one to hand his side the lead when he connected with Gavin Escobar for a 15-yard touchdown.
The Giants took advantage of a generous penalty decision to extend their drive, and they levelled the scores when Eli Manning fired into the endzone to wide open Odell Beckham to make the catch for the nine-yard touchdown.
New York capitalised on a turnover as a slip from Dez Bryant allowed Prince Amukamara to intercept a Romo pass. Manning immediately fired downfield for his tight end Daniel Fells, who bounced off a tackle and ran in for a 27-yard touchdown to fire his side ahead.
However, Dallas hit straight back after a big run from DeMarco Murray put them in the Giants' side of the field, and Romo completed the score when he found Terrance Williams at the back of the endzone.
