EAST RUTHERFORD, N.J. — Dallas Cowboys receiver Dez Bryant scored two touchdowns in the second half to give his team a 31-28 comeback win over the New York Giants Sunday night at MetLife Stadium.

The Giants, who had jumped out to a 21-10 halftime lead, quickly reverted back to their disturbing brand of sloppy football in the second half, particularly on defense, where they gave up huge chunks of yardage due to blown assignments and missed tackles.

The Cowboys took the lead from the Giants on 14 unanswered points. The first score came on a 45-yard touchdown catch by receiver touchdown Cole Beasley, his first score of the season.

The second score, Bryant’s first touchdown of the game, was set up thanks to an Eli Manning interception picked off by Cowboys safety Barry Church on his 3-yard line, a play that snuffed out a Giants scoring drive.

The Giants did regain the lead briefly, when Manning found tight end Adrien Robinson in the end zone on a 1-yard touchdown play with three minutes left.

However, Cowboys quarterback Tony Romo, who finished 18 of 26 for 275 yards and four touchdowns, had practically all day to stand back in the pocket on a 2nd-and-2 from the Giants’ 13-yard line to find an open receiver for the game-winning score. That receiver was Bryant, who finished with seven receptions for 86 yards.

With the win, Dallas improved to 18-8 in games played following their bye week. They also have won a league-best 25 games played on Sunday night.

The Giants (3-8) are now mathematically eliminated from having a chance to run the table and winning the NFC East division title. They will visit Jacksonville next week.

Dallas (8-3) will have a short week to get ready for a Thanksgiving game at home against the Eagles.

Giants receiver Odell Beckham Jr. accounted for two of the Giants’ three first-half touchdowns, giving the Giants a 21-10 halftime lead.

New York converted seven of their eight third-down attempts on the first half, including four on their opening drive that ended with Beckham’s first touchdown of the night.

A bigger Beckham score came on the first play of the second quarter, when Manning heaved a 43-yard pass to the rookie receiver.

Despite having Cowboys cornerback Brandon Carr interfere with him, Beckham not only managed to stay in bounds along the Giants sideline, he also broke free from Carr’s grasp to get into the end zone in what was one of the most acrobatic catches made by a Giants receiver since David Tyree’s famous helmet catch in Super Bowl XLII.

Beckham finished with eight receptions for 125 yards in the first half, and had his third 100-yard receiving game in the last four weeks.

The Cowboys’ points included a 38-yard field goal by kicker Dan Bailey on their second drive of the game, and a 4-yard touchdown catch by tight end Jason Witten in the second quarter.

The Giants, who racked up 237 yards of offense in the first half, capped their scoring for the half when rookie running back Andre Williams scored on a 3-yard run to make it 21-10.
