Luton are continuing to cause Brentford problems in west London.

Harry Cornick flicks a header from Kazenga LuaLua's cross straight at Bees keeper David Raya.

Either side of the keeper and the Spaniard could have been in trouble.

The goal is in the back of the net at the Cardiff City Stadium too.

Rangers striker Charlie Austin nets from close range after Ilias Chair has a dinked effort blocked.

But the goal is ruled out for a high boot on a Cardiff defender Perry Ng, who bravely put his head in in an attempt to clear.

Millwall thought they had doubled their lead as Ryan Leonard hammers in from inside the area.

But it's ruled out for a foul on Terriers keeper Ryan Schofield.

Brentford break away and Ivan Toney has a chance to double their lead, but Luton keeper Simon Sluga is alert and makes the save.

Hatters boss Nathan Jones has made a triple substitution, bringing on Ryan Tunnicliffe, Kazenga LuaLua and Jordan Clark.

Not the debut Cardiff striker Max Watters had in mind.

The man signed from League Two Crawley in a deal worth up to £1m has been substituted 55 minutes into his first Bluebirds appearance.

In fairness to Watters, he got almost no service whatsoever from his team-mates. A tough introduction to the Championship.

Chris Hughton has brought on Anthony Knockaert as he looks for a spark to get Forest back into this.

But so far it's been a performance similar to those earlier in the season, lacking any positive signs.

Rolando Aarons slices an effort wide from inside the area for the hosts.

Huddersfield are facing a third straight defeat unless they find a goal from somewhere.

They may come to rue Fraizer Campbell's first-half penalty miss.

A first sniff for Birmingham - Ivan Sanchez takes a low shot and forces Preston keeper Daniel Iversen into a decent save which gets the ball out of the danger area.

It's not been a classic at St Andrew's...

Chances are at a premium in south Wales in poor conditions.

The visitors are yet to have a shot on target this evening.

Cardiff have brought on Mark Harris for Max Watters. No debut goal for the new signing from Crawley Town.

The visitors have started the better in west London, with the Hatters causing issues with their long throws into the Bees box.

Brentford, without influential skipper Pontus Jansson, are standing firm so far.

Captain Alan Browne has a crack for Preston but his curling effort is just wide.

That's the visitors' first attempt of note at St Andrew's and came after Birmingham had committed men forward.

Half-time change for Forest - Samba Sow, who was booked in the first half, makes way for Lyle Taylor.

Striker Taylor hasn't scored in 13 Championship appearances. Now would be a good time to change that.

The second halves of the four games which kicked off at 19:00 GMT are getting started.

One goal has Brentford, Middlesbrough and Millwall ahead in their games.

Cardiff and QPR are goalless.

Much can change.

Centre-back Paul Huntingdon is making his 300th appearance for Preston - you don't see many players reaching that milestone these days.

Jayson Molumby is making his debut for the visitors in midfield after signing on loan from Brighton.

It's fair to say the conditions are affecting the quality of the game.

They're around 10 minutes in and unsurprisingly it's bucketing down with rain.

Aitor Karanka's Birmingham have gone closest so far, Maikel Kieftenbeld striking over after an error from new Preston signing Ben Whiteman.

With the 19:00 games all at half-time, we'll keep you abreast of the early exchanges in the late kick-off at St Andrew's...

The Canaries go seven points clear at the top of the Championship.

Jordan Hugill scored in each half, a fine header followed by a bundled effort - which arguably should've been ruled out for a foul in the build-up.

Norwich deserve the points, Bristol City never really looked like scoring.

The curse of the former player is in full force at the City Ground, where Britt Assombalonga's goal has Middlesbrough a goal up at the break.

The striker has since hit the post, with Forest yet to really get going despite being on a six-game unbeaten run.

Saman Ghoddos' header has Brentford on their way to their fourth successive league win in their first Championship outing of 2020.

Hold on and victory would lift the Bees up to third in the table.
