Into the last 20 minutes and still we're level.

Both sides looking determined for a goal, but no way through as yet.

Derby's Matt Clarke gets a timely challenge in this time to deny Robert Glatzel poking in a Junior Hoilett cross from the left.

Derby keep conceding possession as they try and play their way out of the back.

But once more Cardiff don't pounce on the error on the counter.

Robert Glatzel and Callum Paterson not quite on the same wavelength with the final ball.

Sean Morrison with the Cardiff long throw this time and Callum Paterson's flick-on at the near post can't find a team-mate.

Frustration for the visitors.

Derby surge forward again and Martyn Waghorn sees a low drive inside the box deflected behind for a corner.

Set piece comes to nothing though as Matt Clarke can't direct a header towards goal.

Derby nearly caught out in possession again that Leandro Bacuna pounces on.

Richard Keogh recovers though and makes the block in his own area that gets it clear.

Cardiff hoping their change in personnel will give Derby something to think about.

Nothing doing as yet but a decent cross gets fizzed in from the left which Kelle Roos is able to claim.

Activity on both benches.

Double change for Cardiff as Nathaniel Mendez-Laing comes on for Josh Murphy. Junior Hoilett comes on for Gavin Whyte.

Looks like Derby will also make a change too in a few moments...

Martyn Waghorn goes close again for Derby as they take a quick free-kick and try and catch Cardiff out.

Tom Lawrence dinks in the quick ball and Waghorn's strike goes narrowly wide of the post.

Plenty of Derby possession but Cardiff sit off and allow them space and make it hard for them to be broken down.

Frustration tells for the Rams as a shot from distance comes to nothing from Tom Lawrence.

Callum Paterson down after it appears Krystian Bielik clips his heels.

Paterson OK to continue after a short pause in action.

Alex Smithies called into action again in the Cardiff goal to keep this level.

Martyn Waghorn with the chance as he runs at the visiting defence and finds a chance to poke a left-foot shot low but Smithies does well to block with his trailing hand and legs.

Leandro Bacuna nearly finds himself striking a ball on target for Cardiff but Derby have numbers to block it on the edge of their box.

Another decent delivery from a free-kick for the Bluebirds that may cause problems in the air for Derby.

Great hit Jack Marriott and it's almost Derby back ahead.

Takes a shot from outside the box that clips the top of the crossbar!

Looks like it took a slight deflection off a Cardiff defender on the way through from his left foot.

No changes for either side by the way at the break so it's as you were.

Krystian Bielik has the potential to play deeper for Derby but he's continuing in that role just in front of their back four.

And away we go again...

There was a bit of Welcome To The Jungle there as well on the PA from Guns 'n' Roses to fire up the crowd.

Wasn't there a story a few years ago that Slash is a Stoke City fan?

Not long to go now until we resume....

More goals to come in this one or will both sides not want to risk another potential defeat?

Let us know how you see it on #bbcefl

Just having a chance to see a couple more replays of that Derby penalty incident during the break and it's fair to say the hosts can feel aggrieved by that decision.

Definite contact from Joe Bennett to bring him down.

Meanwhile, Richard Keogh probably won't want to see that foul on Robert Glatzel moments later too many times.

No doubt about that one.

Right - something to keep you occupied during the interval....

Have you had Championship withdrawal symptoms over the international break?

If so, don't worry, we've devised a little quiz for you to test how much attention you were paying to what some of the Championship's big names were up to during those European Championship Qualifiers and friendlies.

Have a go at seeing if you can match the player with the country they scored for.

Eventful stuff there at Pride Park.

Plenty to debate about those two penalties as well - one that was given and another a few minutes earlier at the other end that wasn't.

I imagine both managers will have their thoughts on it come full-time.

Nothing comes from that second corner, but it concludes a half of plenty of incident and talking point.

Two goals so far - it started with Scott Malone's opener for Derby before Cardiff drew level from the spot with Robert Glatzel's goal.
