Jason Bell, former NFL cornerback, on Sky Sports: "We hyped these teams up and the hype train is real. They have not disappointed us."

Just like the previous game, we enter the final 15 minutes with this one still hanging in the balance.

Anything can happen here, and usually does when these two meet. 'That' final two minutes of their infamous play-off game was the craziest I think we've ever seen.

Patrick Mahomes sees the Bills blitz coming, and steps up just at the right time before flipping a ball forward to Marquez Valdes-Scantling for 33 yards.

Just tremendous play, and recognition from Mahomes to see what was coming and adjust accordingly. We're being spoilt by the QB play in this game tonight.

Right, we're almost playing basketball here so what can Patrick Mahomes do to respond this time?

Isiah Pacheco with a nice run to move the chains early with that trademark angry running style - he'd probably run for a bus like that as well.

Former Dallas Cowboys quarterback Tony Romo on CBS: “Josh Allen's already had big moments in his career. But that's the play right there that's made the Bills believe that this is their time.”

Jason Bell, former NFL cornerback, on Sky Sports: "You will not see a play like that anywhere else. Unreal from Josh Allen."

That is the first touchdown that Chiefs safety L'Jarius Sneed has given up all season.

And maybe some of that fatigue shows as Ty Johnson breaks through with a 16-yard run down to the six-yard line.

Buffalo are back to their punishing ground game that the Chiefs just aren't able to stop, and haven't been all game. The Bills are just at the red zone now and if they keep this up the Chiefs defence will be out of gas sooner rather than later.

In his half-time interview, Bills coach Sean McDermott said that this game will come down to "who's making plays".

"At the end of the day, we've got to make more than them," he added.

Here's another chance for Josh Allen to show what he can do.

And that's a new record for Patrick Mahomes and Travis Kelce who combine for their 16th play-off touchdown.

That takes them one ahead of the Tom Brady to Rob Gronkowski connection that led the Patriots to multiple Super Bowls.

Mahomes and Kelce the best ever to do it?

Former Dallas Cowboys quarterback Tony Romo on CBS: “What an incredible individual effort by Travis Kelce. There wasn't much room there, but nobody's better at putting their head down and finishing at the goal-line.”

We start the second half with Patrick Mahomes going on a 24-yard scamper down the left sideline after faking a jump ball throw to trick the Bills defence.

A different sort of runner to Allen - Mahomes is more of a tiptoe approach while Allen's more of your bull in a china shop type. Both effective though.

Josh Allen has now passed and rushed for a combined 50 touchdowns this season, more than any other quarterback.

In that first half he rushed for two scores and 51 yards - just two less yards than all of the Chiefs managed.

And even when you can block him, on one play he showed he has the skill and awareness to chuck it to one of his team-mates while on the run.

Allen in full flight is a joy to watch. And we have another 30 minutes to come, at least.

A penalty backs the Chiefs up so Patrick Mahomes takes a knee to end the half with the Bills ahead by four points but the game still right in the balance.

Both teams can run the ball, Buffalo looks to have a few more receivers to use though, they're also at home - oh and have Josh Allen who is almost unstoppable with the ball in his hands in the post-season.

Jason Bell, former NFL cornerback, on Sky Sports: "Josh Allen's big and strong. He's looking for an opportunity of a running lane. You just have to give him a little crease and he's so big that he just falls forwards."

Good catch by Khalil Shakir down on the two-yard line low down, just manages to pick it off his toes. And we can guess what's coming up next.
