Marcus Mariota did everything to help the Titans advance in the playoffs, throwing two touchdown passes, running for crucial first downs, and providing the spark needed to rally from a 21-3 halftime hole.
Heck, he even caught one of his own TD passes .
It all added up to a heart-stopping 22-21 victory over the Kansas City Chiefs on Saturday, the first postseason win for the Titans in 14 years.
‘‘Special,’’ said Mariota, whose 205 yards passing included the go-ahead 22-yard strike to Eric Decker with six minutes left.
‘‘I'm part of a great team. I'm part of a group of guys that really believe in each other. And it’s something special.’’
The Titans await the winner of Sunday’s Bills-Jaguars game to see where they will play next weekend. If the Bills win, they will be playing in Pittsburgh on Sunday; if the Jaguars prevail, the Titans will be heading to Foxborough on Saturday.
Derrick Henry added a career-high 156 yards rushing and another score for Tennessee, while a defense fileted by Alex Smith and the Chiefs in the first half pitched a shutout in the second half — dooming the Kansas City franchise to another humiliating postseason defeat.
The Chiefs, with only two playoff wins at Arrowhead Stadium, haven’t won a home playoff game since January 1994, when Joe Montana was the quarterback. The Chiefs beat the Steelers that day.
‘‘I'm in shock,’’ Smith said. ‘‘The swing at halftime to the final whistle, definitely a shock. Yeah. Didn’t feel like we played up to how we’re capable of playing and that’s disappointing.
Only two other road teams have rallied from at least 18 down to win a playoff game. The Cowboys came back from 21-3 in the first half to beat the 49ers, 30-28, in December 1972, and the Lions came back from 27-7 in the second half to beat the 49ers in December 1957.
Smith threw for 264 yards and two touchdowns, but most of that came before halftime.
He couldn’t get going in the second half and misfired on fourth and 9 at the Titans’ 44 with just over two minutes to go, denying the Chiefs a chance for Harrison Butker to kick a go-ahead field goal.
‘‘Grit. It’s just grit,’’ Henry said. ‘‘We told them we've got 30 minutes left, all we've got to do is play our game. Execute the plays and everything will take care of itself.’’
In the first half, the Chiefs looked every bit the team that had won four straight in convincing fashion, and the Titans looked every bit the team that backed into the playoffs.
Kansas City’s Kareem Hunt, the league’s top rusher this season, plunged in from 1 yard for a 7-0 lead. Smith hit Travis Kelce, who later left with a concussion, with a 13-yard touchdown pass, and added another TD toss to Demarcus Robinson on the final offensive play for a 21-3 lead at the break.
‘‘We were feeling good,’’ the Chiefs’ Derrick Johnson said. ‘‘We came in [to the locker room ahead,] 21-3, and that’s all we were talking about: ‘Finish. Don’t get complacent. We have bigger goals than this game.’ ’’
But it was the Titans who finished, and it was Mariota who led the way. He capped a 91-yard TD drive to start the second half in the bizarre fashions: Mariota threw a TD pass to himself.
His throw to the end zone was batted right back at him by Darrelle Revis, and Mariota hauled it in and dived for the goal line.
It was the first time a player has thrown a TD pass to himself in the playoffs, and the first time in any game since the Vikings’ Brad Johnson during the 1997 season.
‘‘Right place, right time,’’ Mariota said with a smile.
Tennessee nearly squandered its momentum when Adoree Jackson fumbled a punt, but the Chiefs were unable to pick up a first down and Butker knocked a 48-yard field goal off the upright. And the Titans capitalized when Henry rumbled nearly untouched 35 yards for a touchdown a few minutes later.
The Chiefs’ offense had been rendered impotent by that point, unable to move the ball after Kelce left with a concussion in the first half.
The Titans blanketed Tyreek Hill whenever he touched the ball, and they stacked the box to slow Hunt down in obvious rushing situations.
Kelce, the All-Pro tight end, was done for the day after sustaining a concussion late in the first half.
Kelce was being tackled when the Titans’ Johnathan Cyprien delivered a blow with his shoulder. Their helmets also collided and Kelce appeared to be dazed. When he got up, he was wobbling toward the end zone and officials called for the training staff.
Finally, the Titans pulled ahead on Mariota’s strike to Decker, and that led to more controversy from the officials. Tennessee went for a 2-point conversion and a field-goal edge, Mariota fumbled as he was getting sacked and Frank Zombo scooped up the ball for 2 points the other way.
But the officials had blown the play dead, ruling Mariota’s progress had been stopped, and the Titans retained the slimmest of margins — one that would stand up to the final whistle.
‘‘I feel really good around our football team,’’ Titans coach Mike Mularkey said. ‘‘I know what I'm going to get from them every week. That’s a good feeling, knowing how they’re going to come out, no matter what.’’
Falcons 26, Rams 13 — Matt Bryant kicked four field goals as Atlanta, the NFC’s No. 6 seed, hung on to win its wild-card game at Memorial Coliseum.
Atlanta’s Matt Ryan was 21 for 30 for 219 yards and salted the game away with a 8-yard TD pass to Julio Jones with 5:48 to play.
With the win, the Falcons will travel to Philadelphia on Saturday afternoon. The next day, the Vikings will host the winner of Sunday’s Panthers-Saints game.
