On the opposite side of the stadium, the Eagles danced and celebrated with loud music inside their locker room.

“Those guys were doing what they ought to do: be excited, since this was one of our goals, even if, hopefully, we have a lot of football left,” Philadelphia Coach Doug Pederson said. “We’ve overcome a lot.”

Chief among those obstacles was a rash of injuries that has sidelined many of the Eagles’ top offensive weapons. In the four-game win streak that closed out their regular season, the Eagles relied on quarterback Carson Wentz, who on Sunday completed 23 of 40 passes for 289 yards with one touchdown and no interceptions. Pederson said his fourth-year quarterback “had grown up,” and that included a growing off-the-field maturity.

“In these last few games he’s put the team on his back and said: ‘Follow me,’” Pederson said. “He’s become a leader, and the young players look to him for that guidance.”

Pederson acknowledged that with a record barely above .500, his Eagles might not be given much of a shot at surviving the postseason to win a second Super Bowl in three seasons. “That’s O.K.,” he added. “Everybody’s record in the playoffs is now 0-0.”

After a desultory first half Sunday that ended with Philadelphia leading, 10-3, the offenses for both teams came alive — at least by N.F.C. East standards — and combined to score three touchdowns in the third quarter.

On the Giants’ first drive of the second half, a 20-yard touchdown pass from the rookie quarterback Daniel Jones to Golden Tate tied the game at 10-10. The Eagles responded with a nine-play drive that ended with Boston Scott’s 7-yard touchdown run up the middle of the Giants’ porous defense.
