Sander Berge breezes forward for Sheffield United. It looks like he is just going to cut through the Blackburn defence but eventually his run is halted right on the edge of the box.

Pudding-Head Wilson: Very fortunate but Sheffield United won't care.

Willem Mevius: I can understand the penalty, but not the yellow card: either the handball was deliberate and it's a red card, or it wasn't and it's no card. Unless he was complaining too much about the penalty decision?

Five minutes to go until the break. I think we all need the 15 minute breather because this has been a relentless FA Cup tie.

Iliman Ndiaye plays a wonderful backheel for Oli McBurnie, who tries to replicate the flick to send Ndiaye away but with no success and Blackburn are able to sweep up.

Harry Pickering heads behind a really good ball into the box by James McAtee and Sheffield United have another corner. Tommy Doyle delivers but Blackburn clear.

Free header!

Dominic Hyam rises highest to meet a free kick and he has all the goal to aim for but he puts his header too close to Wes Foderingham, who pushes over.

Half an hour into an absolutely exhilarating FA Cup tie. Both sides are giving every ounce of what they have in this. It is exhausting just to watch.

When it came out of the area, I'm thinking 'surely not!'

It takes a deflection, it goes right into the corner and the goalkeeper has no chance.

That has lit up Sheffield United.

Ben Brereton has scored all eight penalties he has taken in all competitions in English football (excluding shootouts), including two in the FA Cup.

Cool penalty under pressure.

You know his quality, but he struck it so well. Goalkeeper goes the right way, but there was too much power.

Replays show Sam Gallagher's shot did hit Jack Robinson's hand. Robinson is also getting a yellow card as Blackburn are awarded a penalty.

The referee is going to the screen. Usually only one outcome here...

Suddenly Blackburn have a great chance as Sam Gallagher is picked out by a cross but his shot is blocked by Jack Robinson before Wes Foderingham pushes it over.

James McAtee is starting to get into the game.

Look how he moves the ball in tight areas, he is one to watch in the future. Man City like him so much.

James McAtee is such a livewire for Sheffield United. He's probably been the best player on the pitch so far and he drives forward again into space before taking a shot, but it is blocked on the edge of the area.

The Blades have another corner but Anel Ahmedhodzic heads it well wide.

Play is swinging from one end to the other at a frenetic pace and Jack Robinson has to hook the ball away as Sam Gallagher threatens to power through.

Sheffield United are playing so well.

Diagonal passes, short into feet, good overloads and they've been a threat at set pieces.

Sheffield United have really come into this now and are the better side who have had the better chances.

They have a corner, their first of the game, and it goes flying into a crowded box but no-one can get a crucial touch.
