Arlington, Texas — DeMarco Murray moved ahead of Jim Brown in the NFL record book. Tony Romo moved the Cowboys up and down the field for their sixth straight win.
Murray broke Brown's 56-year-old mark with his seventh straight 100-yard rushing game to start a season, Romo threw three touchdown passes and the Cowboys beat the Giants, 31-21, Sunday.
"He's off to a good start," Cowboys coach Jason Garrett said of Murray. "It's a team thing. Teams are coming in here trying to stop the run. It starts with the offensive line, the tight ends are blocking the backs are blocking.
Romo had a fourth scoring pass overturned on replay. Instead, Murray wound up with his seventh rushing touchdown of the season on a 1-yard plunge.
He finished with 128 yards on the ground to pass Brown, who hit the century mark in the first six games of the 1958 season for Cleveland.
The Cowboys (6-1) are off to their best start since winning six of their first seven on the way to a 13-3 finish in 2007, when they were the top seed in the NFC before losing to New York in their first playoff game.
Eli Manning had three touchdown passes for the Giants (3-4), who have lost road games to the NFC East's top two teams in consecutive weeks. New York now has two-game skids on either side of a three-game winning streak.
Dallas tight end Gavin Escobar had his first two-touchdown game, and Dez Bryant finished with a season-high 151 yards receiving. Romo was 17-of-23 for 279 yards with an interception.
Bryant had a touchdown taken away when he stretched his left arm over the goal line as he was being tackled by Prince Amukamara. The call was overturned on review, and Murray scored on the next play for a 28-14 fourth-quarter lead.
Murray didn't return in the first half after falling down in the open field on his longest run before halftime, a 21-yard sprint around right end. He spent a few minutes with trainers on the sideline but didn't leave the field.
Murray, a fourth-year back from Oklahoma, returned in the second half and broke Brown's record on a 1-yard plunge early in the fourth quarter after a 15-yard carry put him on the verge of setting the mark.
"DeMarco is at the highest level at his position. Dez is at the highest level at his position," Romo said. "We're a balanced team. It's hard for teams to figure out what they want to take away."
After the Giants pulled within seven on Odell Beckham Jr.'s second touchdown catch, Murray had seven carries on a time-killing drive to Dan Bailey's 49-yard field goal for a two-score lead with 1:05 to go.
New York tight end Larry Donnell had team highs of seven catches for 90 yards but fumbled twice.
