ICYMI, some Aston Villa fans were leaving before the half-hour mark against Manchester City earlier...

Damien Williams rushes for two first downs, getting Kansas City up to Houston's 14-yard line.

Patrick Mahomes passes to the running back for another four before the Chiefs settle for a field-goal attempt, Harrison Butker making no mistake from 24 yards.

No joy this time for Houston. They have to hand it over on downs after gaining 33 yards from six plays.

I said earlier how this could be the start of a new era of quarterbacks in the NFL.

If that's the case, where do I sign? I want in!!

Kansas City have now scored seven touchdowns from seven consecutive possessions - that's an NFL record for the post-season.

And quarterback Patrick Mahomes is up to 310 passing yards.

It was a wretched start by the Chiefs but Patrick Mahomes is back in the kind of form that earned him last season's MVP award.

He hits Sammy Watkins for 28 yards before making an eight-yard pass to Blake Bell for the touchdown - 72 yards over just four plays from Kansas City.

Patrick Mahomes finds Travis Kelce for another big gain - 23 yards - as Kansas City end the third quarter in possession. They're up to Houston's 36.

Houston's scoreboard is finally ticking over again. Deshaun Watson gets in from five yards to give them hope.

And Deshaun Watson has got the chains moving again for Houston. He finds DeAndre Hopkins for 21 yards and although Kenny Stills is sacked attempting a trick-play pass to Watson, the Texans' QB hits Will Fuller for 39 yards on the next play. Houston are within five.

After the Texans stretched their lead to 24-0, the Chiefs have scored an unanswered 41 points to lead by 17.

Game over? All I'm going to say is that Houston fought back from a 16-point deficit before winning in overtime at Buffalo last week.

As for the Chiefs, here's their mascot after that shocking start...

Let's just remind ourselves what's happened in this game.

After the Texans' third touchdown put them 21-0 up, Deshaun Watson was doing an air guitar.

We haven't got any footage of that but here he is doing the celebration earlier in the season.

Robert Tomlinson: The Chiefs can score points quicker than any other team in the NFL.

Andrew Hayward: When I landed in Houston, the Houston Texans were 24 points up. In the time I've been here, the Chiefs have scored an unanswered 34 points. Not sure whether I need to apologise to Houston, or if Kansas owes me.

And it's now 41 unanswered points Andrew too.

That's now 41 unanswered points by Kansas City. They've scored a touchdown on their last six possessions.

They're the first team to do that in the play-offs since Brett Favre's Green Bay Packers in 2007.

Damien Williams then runs up the middle and although the Texans stop him getting into the endzone, the running back broke the plane for another touchdown. He and Travis Kelce now have three apiece.

Patrick Mahomes has thrown for four TDs and 238 yards. He's also rushed for 56 from four carries.

The Chiefs quarterback has been aided on this drive by three defensive penalties though, helping Kansas City get up to Houston's five-yard line.

Travis Kelce started slowly. But what a second quarter. He caught three touchdown passes and now has nine receptions for 111 yards.

The tight end is now back on the field despite a hamstring problem and has taken a 28-yard catch to start the Chiefs' latest drive.

The Texans go three-and-out. A chance for us all to regroup.

And for me to dig out some stats for you...
