This game is a cracker, and we've got another coming up later where the San Francisco 49ers are big favourites against the Packers.

Rightly so given their performances over the season - but Green Bay showed in Dallas last week that they can pack a punch.

This one will not be easy...

It's still fairly similar for yards gained but two stats stand out. The Ravens have only 23 passing yards and the Texans have only 14 rushing yards.

Their defence really took the game to Lamar Jackson at the end of the half. He's been sacked three times for a loss of 29 yards.

But it could have been even better for Houston as they gave up 50 yards through a total of eight penalties.

What a half! Defence from both sides has been top drawer - energetic, angry, hard-hitting, and Lamar Jackson and CJ Stroud have had to produce sheer quality just to get any points on the board.

You have to hand it to Houston though, after a tough start, to hang on in there and actually end the half on the front foot. They should be ahead but have plenty to build on.

Are Baltimore rusty? Are they feeling the pressure? If they are then it's only going to get worse as these Houston Texans don't look like they're going anywhere!

Lamar Jackson takes a big hit from Christian Harris this time as Baltimore lose another 13 yards on the sack as they're driven backwards by a rampant Houston defence.

Baltimore left facing a laughable third and 32 - you don't see many of those!

Lamar Jackson takes the field on his own 38 and just needing a few yards to give Justin Tucker a shot at a field goal.

But he can't find anyone, or any room to run and he's taken down for a big loss.

Ka'imi Fairbairn misses from 47 yards! He'd made his last 38 kicks from inside 50 yards but misses the most crucial of the lot.

Houston had just started to get on top and that drive will give them huge confidence - but those lost three points will feel massive, and could be come the end of the game.

Again - kickers and special teams can make all the difference in the play-offs.

Great work from CJ Stroud and Nico Collins to combine for a 29-yard conversion on third down, which could be huge.

They follow-up with another 16-yard gain for Collins as Houston creep into long field goal range.

A nice time for a break with Houston facing a third and 13 after more noise from these fans causes a penalty on the visitors.

It's a proper play-off game this one with some bone-crunching defence dominating, leaving our two quarterbacks scrapping for every yard.

What a response from the Texans. Not only have they halted the Ravens, they've forced them to go three-and-out on back-to-back possessions and returned a punt to the end zone to boot.

Don't forget, two of their six touchdowns last week were by their defence. Now they're scoring on special teams.

That kind of form tends to take you deep into the play-offs. And what a confidence boost right before the half. If they didn't believe they're capable of upsetting Baltimore before, they will now!

They got two pick sixes last week and Houston's defence almost picked off Lamar Jackson, a play after almost sacking him as the visitors start to turn the heat up on defence.

"Defence wins championships" they say, and Houston's rearguard has definitely come to play tonight with head coach DeMeco Ryans, a former linebacker, having them fired up.

Baltimore have to punt for the third time.

Three-time Super Bowl winner Troy Aikman: "In a game like this, when the offence can't get anything going, can you make a difference in the kicking game? The Texans just did."

"Everybody but the centre" may be the best penalty in the book as all of Baltimore's offence took off apart from the man holding the ball who stood like a statue.

Jackson then goes on a wander looking to gain the yards back, but after slipping three tackles he's finally brought down after getting just a yard.

The Ravens will punt.

They get Lamar Jackson this time, but only just! And he had acres of space in behind had he not been captured by the Texans defence so that was a vital sack in more ways than one.

Devin Singletary gets one run away but this Baltimore unit only allowed 109.4 rushing yards per game last year while Houston didn't average over a 100 on the ground so it's a one-sided contest so far.

That shows when the Texans have a run stuffed on third and one, and DeMeco Ryans is in no mood to game on getting that one yard on fourth down, so they kick it away.

Bet they'd love a 'tush push' play in the book to lean on.

This is shaping up to be a hard-fought contest, just what you'd expect from the divisional round.

The offensive stats had pretty even until that drive, which saw Baltimore get their run game going.

The Ravens had the best rushing record in the regular season and if the Texans cannot find a way to halt them, that could prove the difference between the two teams.

Lamar Jackson again! Houston's defence again opens up and Jackson is off and races all the way down to the two-yard line.

The Texans have to be so careful not to leave the middle of the field so open like that, as soon as the big men go beyond the quarterback, he's off.

Zay Flowers is blooming in the play-offs! Jackson running out of time but just has enough to fire a ball to the right sideline for the rookie to take a nice catch and plant two feet in bounds.

“It’s amazing this rookie quarterback [CJ Stroud], going into this hostile environment and making big throws. He’s just so relaxed back there, the moment isn’t too big for him” - Jason Bell, former NFL cornerback, on Sky Sports
