ARLINGTON, Texas — Eli Manning stood on the New York Giants’ sideline in disbelief when it looked as if the Dallas Cowboys had scored a go-ahead touchdown with 10 seconds left.
What was encouraging is what he didn’t see: a replay on the giant videoboard that hangs above the field at Cowboys Stadium, where the Giants still have never lost following a wild 29-24 victory Sunday.
Officials reviewed and overturned Dez Bryant’s apparent 37-yard touchdown catch, ruling his hand hit out of bounds, and the Cowboys couldn’t get into the end zone after the overturned reception.
‘‘I couldn’t quite believe they were able to hit a touchdown in that situation. I kind of kept looking for the replay,’’ Manning said. ‘‘You know the game was not going to be over until that clock hit zero.’’
This was the 20th time in Manning’s career that the Giants rallied in the fourth quarter to win. And this comeback came after New York blew an early 23-0 lead.
‘‘It speaks about our resiliency. We know how to win these games,’’ wide receiver Victor Cruz said. ‘‘We've been in a bunch of them.’’
The Giants (6-2) won for the sixth time in seven games since a season-opening home loss to Dallas. The Giants are 4-0 in Arlington since Jerry Jones’s football palace opened in 2009 with a New York victory.
‘‘I'm very disappointed right now,’’ Jones said. ‘‘I thought after all that, our defense played well enough, our offense kept going, and I thought we were going to get a chance to pull one out.’’
Coupled with Sunday losses by Philadelphia (3-4) and Washington (3-5), the Giants strengthened their hold on the NFC East lead halfway through their schedule.
New York led, 23-0, just two minutes into the second quarter when defensive end Jason Pierre-Paul returned an interception 28 yards for a touchdown. That was the third of four interceptions thrown by Tony Romo, and Dallas (3-4) finished with six turnovers.
But the Giants didn’t score again until Lawrence Tynes made a 43-yard field goal with 10:20 left in the fourth quarter for a 26-24 lead. He kicked a 37-yarder with 3½ minutes remaining, his fifth of the game.
Manning completed 15 of 29 passes for 192 yards with an interception.
Romo threw for a career-high 437 yards while completing 36 of 62 passes. Jason Witten broke his own Cowboys record with 18 catches, which resulted in 167 yards. Miles Austin had nine catches for 133 yards and Bryant had five catches for 110 yards.
Dallas scored the last 10 points of the first half, then added two touchdowns in the third quarter to go ahead.
None of that mattered after the closing sequence.
‘‘Just tough when you think you've won the game,’’ Romo said. ‘‘It switches as that moment. You put a lot into it, obviously. We put a week’s worth [of emotion] in that one game.”
