KANSAS CITY (AP) — Patrick Mahomes finally got the best of Joe Burrow.

All he needed was a little shove.

Harrison Butker made a 45-yard field goal with 3 seconds left — after Cincinnati’s Joseph Ossai was flagged for a 15-yard penalty for shoving Mahomes after he was out of bounds — and the Chiefs beat the Bengals 23-20 in the AFC championship game to make it back to the Super Bowl.

Kansas City will face the Philadelphia Eagles in the Super Bowl on Feb. 12 in Glendale, Arizona.

The Eagles opened as a 1 1/2-point favorite, according to FanDuel Sportsbook.

There are no shortage of storylines: Kansas City coach Andy Reid goes against his old team — which he led to Super Bowl 39 — in a game that’s also the first match-up of Black starting quarterbacks in the Super Bowl with Mahomes and Philadelphia’s Jalen Hurts.

On top of that, there’s a brother-against-brother showdown between Chiefs tight end Travis Kelce and Philadelphia center Jason Kelce.

“Officially done being a Chiefs fan this season!! ” Jason Kelce tweeted immediately after the Chiefs won.

The Chiefs have been making deep postseason runs on a regular basis ever since Mahomes came to town as the franchise quarterback.

This was their fifth straight trip to the AFC title game and will be their third Super Bowl appearance in that span. They beat the 49ers for the NFL title in the 2019 season, but lost to the Bucs the following season. Prior to this recent run, the Chiefs’ last Super Bowl appearance and only championship was in the 1969 season.

“I don’t think we have any cigars,” Mahomes said with a smile, “but we’ll be ready to go in the Super Bowl.”

The Eagles clobbered the Niners 31-7 in the NFC title game earlier Sunday. They’ve looked dominant in the playoffs so far, also beating the New York Giants 38-7 in the divisional round.

Philadelphia is back in the Super Bowl five years after beating the New England Patriots 41-33 in Super Bowl LII. Now a mostly new generation of Eagles — led by coach Nick Sirianni and Hurts — will come to Arizona to try and win another title. Only six players remain from the 2017 championship team, and the team has drafted 22 current members of its roster since then.

The Chiefs-Bengals game looked as if it was going to overtime before Ossai’s ill-advised play. Mahomes — who was playing on a badly sprained ankle — was running to get a first down in the final seconds as Ossai desperately tried to track him down.

Mahomes was out of bounds when Ossai gave him a shove, sending both players tumbling to the turf. The ensuing 15-yard penalty was enough to push Butker into field-goal range and the kick split the uprights.

A distraught Ossai sat on the bench with his head in his hands, well after the game was over.

The Bengals and Chiefs were playing for the fourth time in less than 400 days and Cincinnati had won the previous three meetings — all by three points. This one was decided by a field goal, too, and all Burrow could do was watch.

The Bengals lost to the Rams in last year’s Super Bowl and they just missed another chance at returning to the title game.

“This is emotional. We worked really hard to get here,” Bengals coach Zac Taylor said. “Any play that people feel like was left out there, you’re going to take it hard. We want guys like that, that this means a lot to, they care about it, care about their teammates. Joseph comes to work every day; he loves being a part of this team.”

The NFC title game was a blowout. Niners rookie quarterback Brock Purdy was injured in the first quarter when Eagles linebacker Haason Reddick drilled his right arm on a play that was ruled a fumble. The Eagles recovered that fumble and the injury proved to be a game-changer.

With Purdy hurt, San Francisco turned to 36-year-old journeyman Josh Johnson, who couldn’t do much before eventually leaving with a concussion. Purdy came back into the game, but could barely throw, and the Eagles cruised to the win. Purdy was 4-for-4 for 23 yards, and Johnson was 7-of-13 for 74 yards.

Running back Christian McCaffrey, who scored the 49ers’ only touchdown on a 23-yard run in the second quarter, even took a few snaps at quarterback. He threw one pass, which fell incomplete. McCaffrey had 84 rushing yards on 15 carries.

Johnson was injured on the opening series of the second half. The 49ers attempted three passes the rest of the game.

Purdy will have an MRI on Monday to determine the severity of his injury.

“My arm felt like it stretched out, a lot of shocks all over from my elbow down to my wrist, front and back, pain all over,” Purdy said. “I couldn’t throw more than 5, 10 yards.”

Hurts had a modest game by his standards after a season in which he was a finalist for MVP. He was 15-of-25 passing for 121 yards and ran for 39 yards and a touchdown, improving to 16-1 as a starter this season. The Eagles (16-3) lost two games that he missed with a sprained right shoulder.

Miles Sanders ran for two touchdowns for the Eagles.

Hurts sat alone at his locker dressed all in purple and he took a few puffs of a cigar as the Eagles celebrated around him. He understood there was one more game to win.

“I never knew how far we’d go,” Hurts said, “but I never said it couldn’t be done.”
