The Buffalo Bills are in the NFL playoffs.

No, we’re not kidding.

They needed some last-minute help Sunday from Cincinnati, which stunned Baltimore 31-27 after Buffalo had won in Miami 22-16. Those results lifted the Bills into the final AFC wild-card spot and a visit to Jacksonville next Sunday.

Eight of the 12 playoff teams are newcomers from last year: the Bills, Titans, Jaguars, Rams, Eagles, Panthers, Saints and Vikings. That includes two teams that finished last in their division in 2016 and won it this season: the Eagles and Jags.

The returnees are the Falcons, Patriots, Steelers and Chiefs.

The last time Buffalo reached the postseason, the Bills lost in the Music City Miracle game in Nashville after the 1999 season. Their playoff drought, 17 seasons, was the longest current string in North American professional sports.

“Well I started crying, if that’s a good reaction,” former Bills running back Thurman Thomas told The Associated Press.

But the happiness comes with a caveat: star running back LeSean McCoy was injured and carted off in the second half. He was seen in a walking boot after the game.

Baltimore’s late meltdown was stunning. All the Ravens needed to do to advance was stop a fourth-and-12 play from their 49 in the waning moments. But Andy Dalton found Tyler Boyd with 44 seconds left for a touchdown to pull out the win — and send the Ravens home.

Baltimore had trailed most of the game before taking a 27-24 lead with 8:48 remaining.

Tennessee had a win-and-get-in scenario and took advantage by beating the AFC South champion Jaguars 15-10. That gave the Titans their first playoff berth since 2008. They head to AFC West winner Kansas City on Saturday to open the wild-card round.

“It’s an unbelievable feeling,” linebacker Brian Orakpo said.

The Falcons will get another chance to reach the Super Bowl, though this time as a wild card.

“All you want is an opportunity,” said Falcons defensive tackle Grady Jarrett, who had a sack and three tackles for losses. “We have one. Now it’s up to us to take advantage of it.”

The team that blew a 28-3 lead in the second half of the big game in February defeated Carolina 22-10 to earn a trip to the NFC West champ Rams on Saturday night. The Rams are in the playoffs for the first time since 2004, when they were based in St. Louis.

Los Angeles sat most of its regulars in losing to San Francisco 34-13. Rams coach Sean McVay called the loss “humbling” but didn’t second-guess the decision to rest the stars.

“You certainly try to win the game,” he said. “But when you look at the way we approached it, we feel good about being able to allow some of players to get some rest, some recovery time that I think is much needed for those guys, and then you keep a couple of guys out of harm’s way.”

Seattle fell short of reaching the postseason with Atlanta’s win, but lost anyway to Arizona 26-24.

The Panthers already were in, and they will meet NFC South foe and division winner New Orleans on Sunday to finish the opening round. The Saints swept their two meetings with Carolina this season.

New England (13-3), as it almost always seems to do, secured the top seed for the AFC playoffs by beating the Jets 26-6. Pittsburgh (13-3) got the No. 2 seed — its controversial loss to the Patriots in Week 15 was the tiebreaker — with its 28-24 victory over Cleveland.

The Patriots and Steeelers are off next weekend.

Minnesota (13-3) already had qualified for the postseason, and it grabbed a wild-card round bye with a 23-10 win over Chicago. The other bye in the NFC went to Philadelphia (13-3), which last week locked up the top seed. The Eagles played plenty of backups in a 6-0 defeat to Dallas.
