The regular season went down to the last game, and it was coach Tom Coughlin’s Giants (9-7) who won the NFC East and returned to the postseason for the first time since 2008.
The loss left the Cowboys (8-8) out of the playoffs for the second consecutive year.
New York earned a wild-card home game next Sunday against the Atlanta Falcons (10-6).
Even without any Tim Tebow heroics, the Denver Broncos won the AFC West.
They did it despite falling 7-3 to the Kansas City Chiefs on Sunday because San Diego knocked off Oakland 38-26. The Broncos and Raiders tied for the division lead at 8-8, but Denver won on the tiebreaker, better results in common games.
Baltimore (12-4) took the AFC North and a first-round bye as a No. 2 seed when it outlasted Cincinnati 24-16. Even though the Bengals lost, their 9-7 record earned them a wild card in a head-to-head tiebreaker over Tennessee.
Pittsburgh (12-4) is the other wild-card. The Steelers, who beat Cleveland 13-9, will be at Denver next weekend. Cincinnati visits Houston (10-6).
The Patriots (13-3) earned the right to stay at home throughout the AFC playoffs after a 49-21 victory over Buffalo, which led 21-0.
San Francisco (13-3), under first-year coach Jim Harbaugh, the 49ers will be the No. 2 seed in the NFC behind Green Bay (15-1) after a 34-27 win at St. Louis.
New Orleans (13-3) is seeded third after a 45-17 win over Carolina.
The Saints will play host to Detroit (10-6), which lost at Green Bay 45-41.
