Buffalo Bills 12-21 Kansas City Chiefs

Josh Allen finds Dawson Knox but he's short at the two-yard line.

Buffalo kick the field goal as Tyler Bass lands a 20-yard chip shot.

The officials are deciding whether Josh Allen went out of bounds on a passing play that went wrong.

If he was, it's a six-yard loss and makes Buffalo's job more difficult.

Only around 20 seconds remain until half-time.

The officials say he wasn't out of bounds so Buffalo stay at the three-yard line on third and goal.

Buffalo really have not got star wide receiver Stefon Diggs involved thus far.

Diggs led the NFL in receiving yards in the regular season with 1,535 but has had just two catches for 12 yards tonight.

Josh Allen instead turns to John Brown for an eight-yard gain but Buffalo have a third and 2 with a minute of the half remaining.

TJ Yeldon converts. First down Bills.

Sensational scrambling from Josh Allen as the Bills quarterback finds TJ Yeldon for a 20-yard gain when it looked for all the world he was going to be sacked.

Allen follows that with a fake hand-off and a run to get Buffalo inside the Chiefs' 20-yard line at the two-minute warning.

A promising start to Buffalo's latest drive.

Josh Allen finds touchdown scorer Dawson Knox to move the Bills across midfield.

Just under three minutes left in the first half and the Bills need to reduce the deficit before the interval.

A big third down upcoming with Kansas City still on their own side of the halfway line.

Unbelievable from Patrick Mahomes - he's being tackled by a Bills defender but still manages to pick out Travis Kelce.

He does the same again on the next play, evading all sorts of pressure before locating Tyreek Hill for a big gain, 33 yards.

Three and out for the Bills who have lost all of their momentum.

Josh Allen was fortunate not to be picked off by cornerback Charvarius Ward on a very loose first-down throw.

Buffalo started this game so well but have lost their way slightly.

The old saying that 'offense wins games but defense wins championships' probably doesn't apply here.

The top two offenses in the entire NFL have made it to the AFC Championship game.

Kansas City led the way with 303.4 passing yards per game during the regular season, with Buffalo not far behind on 288.8.

Wow. Mecole Hardman is really making up for that touchdown-costing earlier fumble.

He follows up his touchdown score with a scintillating 50-yard run to put Kansas City in prime position to go ahead for the first time.

Kansas City's rough-housing pays off as they charge Bills quarterback Josh Allen on third down.

Allen tries to throw the ball away but it fails to reach the line of scrimmage and he's penalised for intentional grounding.

A messy drive that and now the Bills have to punt the ball back to Kansas.

Chiefs' defender Bashaud Breeland channels his inner Brock Lesnar with what can only be described as a WWE style German suplex on Bills wide receiver Stefon Diggs.

Unsurprisingly a penalty flag is thrown.

Kansas City defender Chris Jones is very lucky not to be ejected from this Championship game.

He swings a punch at Jon Feliciano but the officials don't see it. Jones would have been in the locker room if they had.

Well, I imagine few expected the Chiefs to be scoreless at the end of the first quarter but here we are.

It might not stay that way for long, however, as they are pushing for a score.

A shovel pass from Patrick Mahomes to Travis Kelce begins the second quarter and gets Kansas City a first down on the three-yard line.

Byron Pringle reels in a Patrick Mahomes pass but is a yard shy of a first down.

The Chiefs go for it on fourth down - and Mahomes connects with Darrel Williams for a first down.

Kansas City are driving well here.

The Chiefs are not quite looking their usual clinical selves, as evidenced by an atypical drop from the NFL's top tight end Travis Kelce.

But he makes amends a few moments later, following up a catch from Tyreek Hill - and the Chiefs are around the Buffalo 30-yard line.

Nick Hughes: May be a Giants fan, but really hope the Bills can pull it off tonight - they have the talent to do it. I'd love to see them win it all after that run in the early 90s.

Ian: If the Bills win tonight will be very interesting to see if Josh Allen gets labelled as the future GOAT rather than Mahomes.

What a start for Buffalo, who have been nowhere near an AFC Championship game since the mid-1990s.

They lost four straight Super Bowls from 1991-94. Little wonder they haven't wanted to get back there since.
