KANSAS CITY, Mo. — Hobbling along on an injured ankle, Patrick Mahomes threw for 195 yards and two touchdowns Saturday night, leading the Kansas City Chiefs to a 27-20 victory over the Jacksonville Jaguars and a spot in their fifth straight AFC title game.

Mahomes missed most of the second quarter after his ankle was landed on by a Jacksonville defender. But the All-Pro quarterback returned in the second half and, relying on guts and guile, led the Chiefs on a 75-yard TD drive in the fourth quarter that helped to ensure a date with the Bengals-Bills winner for a spot in the Super Bowl.

If Cincinnati wins Sunday, the AFC title game will be played at Arrowhead Stadium. If Buffalo wins, it will be in Atlanta.

“I mean, it’s a credit to the guys around me,” Mahomes said. “The offensive line kept me clean in the pocket, knowing that I couldn’t move, and guys made plays around me. That’s what a great team does, is when somebody gets a little banged up, everybody around them steps up.”

The question on everyone’s mind – Will Mahomes be available next week? – might be no question at all.

“Yeah, X-rays were negative and they haven’t diagnosed anything yet,” he said, “but I’ll be good to go.”

Travis Kelce had a career-high 14 catches for 98 yards and two touchdowns for Kansas City. Isiah Pacheco ran for 95 yards, while Marquez Valdes-Scantling hauled in the eventual winning touchdown pass with about 7 minutes left.

The Jaguars, who rallied from a 27-0 deficit to beat the Chargers in the wild-card round, squandered two chances to mount another late rally. The first ended when Jamal Agnew had the ball pop loose inside the Chiefs 5 with about 5 1/2 minutes to go, and the second when Jaylen Watson made a leaping, one-handed interception to take the ball away again.

The Jaguars’ last-gasp chance ended when Kansas City recovered an onside kick with 24 seconds to go, after a field goals the deficit to 27-20.

Lawrence finished with 217 yards passing with a touchdown toss to Christian Kirk, who was briefly hurt midway through the fourth quarter but returned to finish the game. Travis Etienne had 62 yards rushing and a touchdown.

Long before Mahomes hobbled to the sideline in pain, he was at his creative best, driving the Chiefs downfield on their opening possession. There was a shortstop-style sidearm sling to JuJu Smith-Schuster, a key third-down pass to Kelce as he was being dragged to the turf, and the flip pass to his tight end that gave Kansas City a 7-0 lead.

The Jaguars came right back, taking advantage of a big kickoff return and a short field. Lawrence, whose four touchdown throws helped to stun the Chargers last week, proceeded to hit Kirk for a tying touchdown.

Then, the complexion of the game changed.

Mahomes was moving up in the pocket when Key brought the full weight of his body down on the star quarterback’s right ankle. Mahomes hobbled to the huddle and managed to get through three more plays to end the first quarter, then was on the field two more plays before Harrison Butker kicked a 50-yard field goal.

During the Jaguars’ ensuing possession, Mahomes got into a heated argument with Chiefs Coach Andy Reid and the training staff. He then threw down his coat and headed to the locker room, and Chad Henne took over midway through the second quarter, much as he did two years ago in a playoff win over Cleveland.

The 37-year-old journeyman, who once started for the Jaguars, led Kansas City on a 12-play, 98-yard touchdown drive.

“Yeah, I did not want to go (to the locker room) and they kind of gave me the ultimatum that I wasn’t going back in (the game) unless I went in there,” said Mahomes.

“They’re trying to take care of me. We’ve got a lot of great people over here, but it’s going to take a lot to keep me out of a football game.”

Mahomes returned to the field and cheered on his teammates from the sideline, wearing a puffy winter coat on a cold, sleeting night at Arrowhead Stadium.

Then the fans suddenly were cheering for Mahomes again. He trotted onto the field to start the second half, his right ankle heavily taped. Mahomes was still struggling to move around, but simply his presence seemed to calm the Chiefs – and their angst-filled fan base.

Butker added a second 50-yard field goal late in the third quarter to extend their lead to 20-10.

But the Jaguars proved in the wild-card round that they can deal with deficits. And rather than wilt amid the crowd noise, they rose to the occasion, putting together a 75-yard touchdown drive that kept them in the game.

Their comeback ended, though, with two late turnovers and a failed onside kick.
