Arlington, TX (My Sportsbook) - Lawrence Tynes' 37-yard field goal as time expired ended a back-and-forth NFC East battle, as the Giants went into brand- new Cowboys Stadium and left with a 33-31 victory over arch-rival Dallas.

The Cowboys went ahead 31-30 with 3:40 remaining on Felix Jones' seven-yard touchdown run. That left plenty of time for Eli Manning to bring the Giants into field goal range.

Aided by a pair of third-down completions during the final drive -- the last off a tipped ball -- Manning set Tynes up for the game-winner with the clock showing four seconds.

The Cowboys tried to freeze Tynes with a late timeout but to no avail, as the kicker split the uprights to spoil Dallas' historic home opener.

The palatial new home for the Cowboys, which cost $1.15 billion to construct, is already part of NFL history, setting a regular-season attendance record in the first meaningful game played there. The 105,121 tickets distributed on Sunday eclipsed the 103,467 sold in a game between Arizona and San Francisco in Mexico City in 2005.

Manning ended with 330 yards on 25-of-38 attempts with two touchdowns. Mario Manningham and Steve Smith had their way with the Dallas secondary. Each receiver hauled in a touchdown and 10 receptions, while Manningham went for 150 and Smith for 134 yards for New York (2-0), which bested another divisional opponent, Washington, in Week 1.

Tony Romo, fresh off a career-high 353-yard effort in season-opening win against Tampa Bay last week, was picked off three times for Dallas (1-1). The QB connected on just 13-of-29 throws for 127 yards, adding a touchdown toss to Jason Witten.

Marion Barber ended with 124 yards and a score on 18 carries, while Jones chipped in 96 rushing yards and a TD on seven carries but fumbled away a kickoff return.
