Rookie quarterback Daniel Jones made his Giants debut on Sunday in the team's 35-17 loss to the Cowboys.
Jones appeared late in the fourth quarter with less than two minutes to play, taking the field for Eli Manning.
Jones fumbled on the first drive, which was then recovered by the Cowboys, after an overturned call. He finished 3-for-4 with 17 yards. Manning went 30-for-44 with 306 yards and one touchdown.
The Giants next face the Bills on Sept. 15, while the Cowboys will take on the Redskins on the same day.
