And now we have had a flurry of chances at the Riverside.

Middlesbrough have a deflected effort sail just wide, but moments later the Hatters have a great opportunity to take the lead.

A scrappy corner eventually falls to Sonny Bradley, but the defender can only poke the ball wide.

Finally something for Derby keeper David Marshall to stick his teeth into.

First he punches away a free-kick after the ball was headed up in the air by a Rams defender, then he races to the edge of his area to punch away a cross.

Swansea are still dominating the game, but the hosts are holding firm.

Five minutes gone at the Riverside. Derby were already 1-0 up at this stage.

We haven't had any chances to shout about just yet. Still, it's early days.

Derby make their first change of the evening.

Duane Holmes comes on for Martyn Waghorn.

Fresh legs should keep the pressure up on the Swans when they have the ball.

Time is running out for the visitors to get back into the game.

Meanwhile, we've now kicked off in two more Championship games with Middlesbrough hosting Luton and Cardiff taking on Birmingham.

Into the final quarter of the game and if Derby hold on they will only be inside the relegation zone on goal difference.

The Rams are set to move level on points with Nottingham Forest and Rotherham United, who face Blackburn later.

First booking of the evening as Andre Ayew gets a yellow for an off-the-ball tangle with Derby centre-back Matt Clarke.

That's a moment of pure frustration.

Both players are back up on their feet and get the all-clear to carry on.

Our two 19:00 GMT kick-offs are just about to get under way.

Swansea are still having more of the ball and probing.

But Derby keeper David Marshall is still yet to make a meaningful save.

There's a break in play after Derby left-back Lee Buchanan clashes heads with Swansea forward Andre Ayew while challenging for a header.

Both players need treatment.

Another change for the Swans.

Middlesbrough boss Neil Warnock has never lost a league match against Luton since his first season in the Football League in 1987-88 (P10 W4 D6).

Boro have been in patchy form, winning two and losing three of their last five. But a victory here would see Warnock's side go just two points off the play-offs.

Luton are a point further back in 12th and start hat-trick hero James Collins up top.

The forward was superb in the Hatters' 3-0 win over Preston on Saturday. Can he net another tonight?

Better from Swansea.

Andre Wisdom is in the right place to clear a dangerous cross into the Derby box.

Steve Cooper's side are asking more questions of the hosts now after their first-half performance was well below their usual standards.

Can they find a way to unlock the Derby defence?

Swansea are still busy probing but can't find a way through the Rams defence.

The hosts are getting back in numbers when needed.

There's a break in play as Derby right-back Nathan Byrne needs a moment to get back to his feet after a clash with Swans sub Ryan Manning, but he's fine to carry on.

It's been a slightly scrappy start to the second half.

Derby are still pressing the Swans well when the visitors have possession.

There is more urgency from the Welsh club though.

All the stats point to a home win in South Wales tonight.

Cardiff have won five of their last seven home league matches against Birmingham since a 2-1 defeat in 2008-09.

And the West Midlands side have only tasted victory in two of their last 15 league matches against the Bluebirds (D7 L6).

Neil Harris' Cardiff were thoroughly beaten by fierce rivals Swansea at the weekend and will be looking to put things right.

Meanwhile, a win for Blues and Aitor Karanka's side could be 12 points clear of the drop.

First chance of the second half as Martyn Waghorn cuts inside from the right flank, but the Rams forward sends his left-footed effort slicing across goal and well wide.

Kyle Naughton, Jake Bidwell and Jay Fulton are the trio who have been hauled off for the visitors.

It looks like the Welsh side have ditched wing-backs and switched to a back-four for the second half.

Will it spark a comeback?
