Kicker Lawrence Tynes nailed a 37-yard field goal as time expired to lift the Giants to a thrilling 33-31 win over Dallas and spoil the Cowboys first game at their new $1.15 billion stadium.
New York's defense forced four Cowboys turnovers, including three interceptions by Dallas quarterback Tony Romo.
Romo's first interception was returned 34 yards for a touchdown by rookie Bruce Johnson to put the Giants up 10-7 in the first quarter.
Quarterback Eli Manning was 25 of 38 for 330 yards and threw touchdowns to wideouts Mario Manningham and Steve Smith for New York (2-0).
"The whole team did a good job of gutting it out," Manning told the Associated Press. "This is a good thing to build from."
Manningham and Smith did their best to make the Giants forget about Plaxico Burress. Each hauled in 10 passes, with Manningham's covering 150 yards and Smith's going for 134.
Not all the news was good for the Giants defense. Defensive end Justin Tuck left the game with a shoulder injury in the first half and Dallas' 251 yards rushing was its most since 1993.
Marion Barber ran for 124 yards and the stadium's first touchdown, and Felix Jones added 96 and a touchdown for the Cowboys (1-1).
Former President George W. Bush, LeBron James and several former Cowboys legends were among a packed house of 105,121 that saw eight lead changes, with neither team ever ahead by more than six.
"Everybody makes a big deal because we spoiled their little party," Tuck told the AP. "Every other game we play in the NFC East will be just as big."
