Patrick Mahomes only needed 13 seconds to save the Chiefs

• The Kansas City Chiefs beat the Buffalo Bills in the greatest shootout in NFL history.
• After the Bills took the lead with just 13 seconds left, the Chiefs looked like their postseason was over.

Patrick Mahomes and the Kansas City Chiefs had their backs against the wall.

After leading the Buffalo Bills for the majority of the day, a chaotic, transcendent final two minutes of offensive mastery from both teams produced two touchdowns for the Bills and just one for the Chiefs.

Josh Allen was electric, finding Gabriel Davis in the end zone for his fourth touchdown of the day with just 13 seconds left in the game to put the Bills up 36-33. The heavyweights were trading blows, but this one felt like a knockout punch.

But somehow, the Chiefs got back up off the canvas. As it turned out, 13 seconds was just enough time for Patrick Mahomes.

After a touchback on the ensuing kickoff, Mahomes needed just two plays to drive the Chiefs into field goal range.

First, he found speedster Tyreek Hill on a short route with blockers in front of him for a 25-yard gain.

The next play, Mahomes connected with tight end Travis Kelce to get the Chiefs in range for a game-tying field goal.

Harrison Butker's kick was true. Overtime.

In the extra period, the Chiefs won the coin toss, chose to receive, and drove the field on the opening possession to score the game-winning touchdown, with Mahomes once again finding Kelce to end the game.

Chiefs 42, Bills 36. Game over.

It was a heartbreaking end for the Bills, who had played a near-perfect game of football, only to lose without getting a chance to play offense in overtime.

After last year's loss to the Chiefs in the AFC Championship, this gut-punch likely hit twice as hard.

With the win, the Chiefs will host the Bengals in the AFC title game next weekend with a spot in the Super Bowl on the line.

If Mahomes and the Kansas City offense are still moving the ball like they did on Sunday night, they'll be tough to stop.
