Blackburn make a couple more changes as they look to see out the game.

Sam Gallagher and Harvey Elliott are withdrawn, with Elliott Bennett and Ben Brereton on for the hosts.

Meanwhile Tom Lawrence comes off for Derby, as Festy Ebosele enters the fray.

Harry Wilson has done everything right, it's rolling in but there's just not enough weight on the ball to beat the defender clearing it off the line.

Another change for Cardiff and it's one Liverpool loanee for another, with winger Sheyi Ojo replacing Harry Wilson.

Great chance for Cardiff as another substitute, Josh Murphy, threads a lovely through ball for Harry Wilson.

Wilson dinks the ball over the onrushing Rafael but it doesn't have the legs, and Andy Yiadom clears off the line.

Reading then get back on the ball, and Cardiff's Ciaron Brown is booked for bringing down Yakou Meite.

Ten minutes plus stoppages remain at Ewood Park, and Derby are showing urgency in their bid to find an equaliser.

As things stand the Rams are four points ahead of the relegation zone, but will have played three more games than 22nd-placed Rotherham after tonight.

Harvey Elliott and Adam Armstrong remain a threat for Rovers on the break.

This is a welcome sight for Reading fans.

Midfielder John Swift has missed the past 14 games through injury but he's back fit and he's back on the pitch.

Swift replaces Andy Rinomhota.

Cardiff finally have their first shot of the second half - but it's a feeble one.

Kieffer Moore takes aim from the edge of the penalty area but his weak low effort just dribbles into Rafael's arms.

Cardiff get a rare chance to attack but, just as they seem to spring into action on the break, Harry Wilson's touch is too heavy and allows Reading's covering defenders to clear.

Mick McCarthy's men still haven't had a shot in this second half.

Rovers keeper Thomas Kaminski flies to his left to punch away Tom Lawrence's knuckleball free-kick from 20 yards out.

The rebound falls to Nathan Byrne and time appears to stand still as the Rams right-back diverts the ball onto the post.

The Rovers defence then scramble the ball away.

As much as we're talking about Reading and how good they've been in possession Cardiff are still holding out for a clean sheet.

That's another good chance for Reading, who are dominating.

Josh Laurent turns neatly inside the Cardiff box and passes to Yakou Meite, who blazes his shot way over the bar.

Yakou Meite has another sight on goal, cutting in from the right again and firing a low shot with his left foot but he drags it wide.

Reading are knocking on the door. Will they get that breakthrough?

Michael Olise's free-kick is aimed at Ovie Ejaria on the edge of the penalty area, but Marlon Pack reads it and clears for Cardiff.

It's all happening at Ewood Park but we're still waiting for a goal at the Madejski Stadium.

In fairness to Kieffer Moore, he's barely had any service leading the Cardiff attack.

The away side can't keep hold of the ball in this second half and Reading now have a free-kick in a dangerous area to the right of the Cardiff box after Perry Ng fouls Yakou Meite.

Kieffer Moore isn't winning his battles so Cardiff City don't have the platform to build their attacks like they normally have.

Reading are really getting on top now.

Yakou Meite cuts inside from the right and shoots with his left foot, and it's deflected for a corner.

George Puscas gets his head to the corner but it's a looping header which Cardiff keeper Alex Smithies catches easily.

Derby keeper David Marshall has been a busy man since the break.

He's been off his line quickly again to deny Adam Armstrong in another one-on-one clash, and the Rovers striker has just tested the Rams captain once more with a left-foot shot from just inside the box.

The hosts have played with much more purpose since the restart.

Lucas Joao fell awkwardly after having that shot saved, and he looks to have injured his shoulder.

The Reading striker is receiving treatment and that's his game done. He looks in pain as he leaves the field.

George Puscas comes on in his place.

First couple of changes to report.

Derby top scorer Colin Kazim-Richards comes on for Louie Sibley, while Joe Rothwell replaces Lewis Holtby in the Rovers midfield.
