Swansea are playing now with a type of urgency now that was needed at the start of the game. it's taken them going behind to spark them in to life a little bit.

Florian Bianchini's corner is headed goalwards by Ben Cabango but Callum Robinson clears.

Hull City win a corner in front of their own fans and Gustavo Puerta takes his time over it.

He eventually swings it in but Lukas Jensen is out well to claim in the Millwall goal.

Jensen tries to launch a quick counter but the Lions end up all the way back on the edge of their own box. Frustrating day so far for the south London side.

Paul Smyth's afternoon is over as he's withdrawn, with Koki Saito on for the Hoops.

Endless energy from the Northern Irishman again today, he's been a key fixture in this resurgent QPR side over the last few weeks.

Swansea's fans shout for a penalty as Jak Alnwick slides out and collides with Josh Key.

The Cardiff keeper appears to get a slight touch on the ball, which probably saves him.

Millwall are trying to force the issue a little more since going behind but as yet, are still to create a chance.

Lions boss Alex Neil makes a change and Duncan Watmore makes way for Macaulay Langstaff.

What a header. It's getting messy for Swansea, and their fans are starting to leave.

Romain Esse completed his move from Millwall to Crystal Palace and his former side are struggling for goals again this afternoon.

Millwall have scored just four goals in their past eight Championship games.

Esse was the club's second top scorer in the league with four before his departure.

Lions fans, how much will you miss him? And do you think he will be a success at Selhurst Park?

I questioned Swansea in the week about the performance in the FA Cup and it looks like they carried it on to this game.

Cardiff have made Swansea work and defend, the two centre-halves have been poor - Harry Darling has had a nightmare.

Swansea might have had one back.

Ronald's cross reaches the unmarked Josh Key at the far post.

The right-back heads across goal, with his header drifting a foot wide as Zan Vipotnik fails to connect at the far post.

Nice play by Michael Baidoo as he gets into the area and lifts it towards the far post.

There's no one there for the hosts but Kenneth Paal heads it behind for a corner, which is eventually gathered by QPR keeper Paul Nardi from the second attempted cross.

The home side just haven't had that quality needed in the final third today, Ryan Hardie is replaced by Mustapha Bundu for Argyle.

Form goes out the window, particularly home form what a second half performance this has been from Cardiff City.

From a Swansea perspective it's really poor defensive work. Nobody is marking Dimitrios Goutas.

The home party is now fully under way at the Cardiff City Stadium.

Swansea look shellshocked. This is turning into their worst derby day in decades.

A nightmare few minutes for Plymouth's Bali Mumba.

It was the right-back's poor throw in that set Rayan Kolli through for his first effort at goal.

And then he got the attempt a controlled touch all wrong to gift Ilias Chair the chance that led to the goal.

Rayan Kolli with a fine first touch before the finish, the weekend after signing a new contract with the Hoops.

Luke Williams is chuntering himself on the touchline.

Omer Riza, by contrast, appears fairly calm.

It's another mistake from Mumba that allows Chair to run through, another good save from Grimshaw initially, and then Kolli follows up.

But it is one of those that is, once again, a mistake of our own making.

Whether we see a couple more changes from Muslic we will see.

Regan Slater just finds a yard of space on the edge of the box for Hull but drags his shot wide.

Another half-chance for the Tigers. They'll be keen to put this to bed if they can.

Swansea are attempting to find a way back into this contest, but they are not causing Cardiff too many problems as yet.

If anything, the Bluebirds look capable of striking again on the counter.

Both sides are making changes and both are introducing new signings for their debuts.

Aaron Connolly is on for his first game for Millwall, replacing fellow full debutant Calum Scanlon.

Leeds loanee Joe Gelhardt is on for Hull in place of Mason Burston.
