KANSAS CITY, Mo. — A generational quarterback got his team to the Super Bowl for the first time in multiple generations.

Patrick Mahomes, the brilliant third-year quarterback, threw for three touchdowns and ran for another as the Kansas City Chiefs beat the Tennessee Titans, 35-24, in the AFC championship game Sunday at blustery Arrowhead Stadium.

They will face the San Francisco 49ers, winners over the Green Bay Packers later Sunday in the NFC title game, on Feb. 2 in Miami Gardens, Fla.

It will be the first Super Bowl appearance for the Chiefs since January 1970 in Super Bowl IV and the first for Mahomes, the NFL MVP in the 2018 season who made a rapid recovery this season from a dislocated right kneecap, returning to the lineup after missing only two games.

He was 23-for-35 passing for 294 yards Sunday as the Chiefs succeeded where they failed last postseason, when they lost the AFC championship game at home in overtime to the New England Patriots. He also ran for 53 yards and was Kansas City’s leading rusher against Tennessee, which was denied what would have been a third straight stunning upset during these AFC playoffs.

“We fell short last year, and we learned from it,” Mahomes said. “We built every single day, and now we have a chance to go to Miami and get the ultimate goal, [which] is the Super Bowl.”

Chiefs Coach Andy Reid, regarded by many as the NFL’s best current coach without a Super Bowl triumph, gets another chance. Reid, while with the Philadelphia Eagles, lost his lone Super Bowl appearance 15 years ago to the Patriots.

“Last year we were four inches short,” Reid said, referring to a key play against the Patriots on which the Chiefs lined up offside. “The guys made it a point to get better than that four inches. … They weren’t going to go through that again.”

Chiefs owner Clark Hunt was able to raise the AFC championship trophy named for his father, Lamar Hunt, the team’s late founder who coined the term Super Bowl.

“Obviously this is a very special day for our family and the entire organization,” Clark Hunt said later.

Mahomes had two first-half touchdown passes to wide receiver Tyreek Hill as the Chiefs overcame early deficits of 10-0 and 17-7. They took their first lead at 21-17 on a dazzling 27-yard touchdown run by Mahomes 11 seconds before halftime. He isn’t known as a runner, but he made at least four defenders miss him and tiptoed his way along the sideline before veering inward near the goal line.

“I broke it and was thinking about just running out of bounds,” Mahomes said. “As I got to the sideline, I realized I could cut up. And I was running down the sideline, and I knew we had two timeouts. So I was like, ‘I might as well try to cut it back.’ ”

Tailback Damien Williams provided a three-yard touchdown run on the second play of the fourth quarter. Mahomes threw a 60-yard touchdown pass to wide receiver Sammy Watkins, who got open behind the Tennessee secondary as Mahomes moved around and bought time on a third-and-six play, and the Chiefs made it 28 straight points after trailing 17-7. The Titans broke that string with a cosmetic touchdown after converting a pass on a fake punt into a first down.

The Chiefs had overcome a 24-0 deficit the previous weekend against the Houston Texans in the divisional round. For other teams, falling behind the Titans, with their potent running game, was a mistake that could not be overcome. For the Chiefs, it was no big deal, given how quickly they can score with Mahomes.

The Titans came one upset shy of being the NFL’s third No. 6 seed to reach the Super Bowl, following the Pittsburgh Steelers in the 2005 season and the Packers in the 2010 season. They had used the bullying running of tailback Derrick Henry to win on the road against the third-seeded Patriots and the top-seeded Baltimore Ravens.

Things looked promising against the second-seeded Chiefs in the first half when Henry ran for a four-yard touchdown after taking a direct snap and quarterback Ryan Tannehill threw a one-yard touchdown pass on a trick play to Dennis Kelly, a reserve offensive tackle who lined up as an eligible receiver on the play.

But the Titans couldn’t close the deal this time, and Tannehill, obtained in an offseason trade with the Miami Dolphins, won’t make a triumphant return to South Florida as a Super Bowl starter. Henry ran for a modest 69 yards on 19 carries Sunday. He was virtually nonexistent after halftime, and the Titans simply didn’t have enough answers for Mahomes on a cold, breezy afternoon in which the game-time wind chill was 5 degrees.

“I felt like we got off to the start we wanted in all three phases,” Titans Coach Mike Vrabel said. “But I think when you play teams like this and teams that are as good as the Chiefs, as explosive as they are, you kind of knew they were going to make a run. … We had some stops that we could not get.”

The Chiefs were able to celebrate Sunday on their home field, a year after watching the Patriots celebrate an AFC title at Arrowhead.

“We all were bitter,” Reid said. “That’s not a good feeling. It wasn’t just me. ... Everybody took responsibility.”
