Sheffield United are on their heels again and concede a corner.

The home side are scrambling to clear and Max Lowe catches Jack Simpson with a high boot.

Sheffield United are living dangerously right now and Cardiff are right up for it!

From a corner, the ball falls for Ryan Wintle to have a go and his fierce shot forces Adam Davies into a save low to his right. An important save, that.

Sheffield United get themselves in all sorts of trouble at the back.

Tommy Doyle tries to clear from inside the area, but hits a team-mate. The ball bounces around loose in the area, but Cardiff fail to punish the hosts after a few bites at it.

They do, however, have a corner.

Sheffield United fans are are making plenty of early noise, not that the home side are delivering much to shout about right now.

They have looked solid on the ball, but little more.

Cardiff City are not seeing much of the ball early on, but Jaden Philogene for one is making the most of whatever he gets.

Sheffield United's defence hang back a little too much and he makes the most of the space with the first shot of the game.

He actually had more time to exploit as he fires harmlessly off target from outside the area.

The ball is floated in, but skips beyond any touch in the area.

Sheffield United will have wanted to at least cause a bit of panic. Instead the visitors are spared.

Cardiff's Jack Simpson feels he has no choice but to get a leg out to stop James McAtee from getting away from him and into space.

His challenge earns him a yellow and a lands Sheffield United a free kick in a dangerous area...

Plymouth Argyle have grown into this game game as we approach the final 10 minutes of the first half.

Finn Azaz had a decent effort blocked for the Pilgrims, who also had a penalty shout turned down.

It's feisty and nervy at St James Park.

A few probing runs from both sides in these early minutes.

Cardiff's Jaden Philogene cuts in from the right, but is shunted off the ball and the hosts break up field at pace.

Space opens up for James McAtee, but the attack comes to nothing. Positive early signs.

Cardiff City boss Sabri Lamouchi was fuming at the start of the week when they were beaten at home by Sunderland.

The defeat left them just one place and one point above the relegation spots.

The Frenchman didn’t mix his words when he came out and publicly questioned the attitude of his players.

What sort of reaction will they come up with today?

And off we go.

Both sides have much to play for, victory feels like a must.

We could be in for a real treat.

They're also under way in the League One derby between Cambridge United and Peterborough. It's still goalless in the Devon derby between Exeter and Plymouth - 30 minutes gone in that one.

Both sides have emerged at Bramall Lane.

The sun is shining and the expectations are sky high.

Kick-off is just moments away.

The picture at the bottom of the table is a grim one for Cardiff City.

The Welsh side start this busy afternoon knowing that anything but a win in their early kick-off leaves them at risk of ending the day in the bottom three if results go against them.

And this is exactly how it looks at the top of the table after last night's win for Middlesbrough.

There is plenty of room for movement in what is a congested race for the play-offs.

And Sheffield United, of course, will want to be keeping their distance from third place.

Sheffield United boss Paul Heckingbottom is forced to make a number of changes for the visit of Cardiff City.

Sheffield United: Davies, Baldock, Egan, Robinson, Bogle, Berge, Doyle, Lowe, Ndiaye, McAtee, McBurnie.

Substitutes: Fleck, Sharp, Norwood, Clark, Arblaster, Jebbison, Dewhurst.

Cardiff City: Allsop, Ng, Kipre, McGuinness, Simpson, Rinomhota, Wintle, Ralls, Philogene-Bidace, Etete, Kaba.

Substitutes: Romeo, Ojo, O'Dowda, Sawyers, Alnwick, Wickham, Davies.

A really competitive start here at St James Park - Exeter have had the only chance of note so far when Demetri Mitchell's effort was saved by Callum Burton.

The hosts are shading it at the moment in a derby which is seeing all the usual tackles and fan noise you'd expect from two fierce rivals.

It's a day for derbies in League One - Cambridge United against Peterborough is coming up at 12:30 BST.

It's a beautiful day in Devon for the county's big game.

Plymouth Argyle come to their biggest rivals knowing victory at Exeter City will bolster their push for an automatic promotion place.

But the Grecians would love nothing more than putting a spanner in the works of the Pilgrims on their home turf.

Plymouth boss Steven Schumacher has made six changes with attackers Niall Ennis, Sam Cosgrove, Finn Azaz all coming in after the 2-0 loss to Lincoln City on Monday, while Exeter are buoyed by the return from injury of Jay Stansfield in one of three changes.

It's still goalless after 15 minutes.
