Richarlison
What's going on?
Everton have turned this tie upside down in the space of a couple of minutes with Richarlison producing a precise strike into the bottom right corner.
From looking very comfortable, Spurs now trail.
Sheffield United 0-0 Bristol City
And it's a red as well for Alfie Mawson.
Sheffield United 0-0 Bristol City
Penalty given!
Sheffield United 0-0 Bristol City
Now then, was it blocked by a defender's hand?
It certainly looks that way and referee Rob Jones is over to his monitor.
Sheffield United 0-0 Bristol City
Oh how has that stayed out? Billy Sharp picks out David McGoldrick in the area, he fires across goal and it is blocked on the line and hits the bar!
A shot then comes in and again it's cleared off the line!
Dominic Calvert-Lewin
Have I mentioned this is a belting tie?
Not for the first time this season Dominic Calvert-Lewin gets his side out of trouble after lashing past Hugo Lloris.
Could the Spurs keeper have saved that? Everton don't care.
The games at Leicester and in Sheffield are into the last half hour. We have had four shots on target combined.
Leicester 0-0 Brighton
It's a triple change for Leicester.
On: Kelechi Iheanacho, James Maddison, Hamza Choudhury
Off: Jamie Vardy, Wilfred Ndidi, Ayoze Perez
Everton 0-1 Tottenham
Everton just about survive another lightning-quick Tottenham counter-attack. Steven Bergwijn is away and has support from Son Heung-Min whose attempt flies off a blue shirt and loops narrowly over the bar for a corner.
Sheffield United 0-0 Bristol City
The snowfall has gone up a notch at Bramall Lane but the game has gone down a few. Nothing much happening.
Everton 0-1 Tottenham

Everton goalkeeper Robin Olsen was criticised for the mistake that gave Scott McTominay a goal at Manchester United on Saturday but he is doing well so far tonight with some decent saves.
Carlo Ancelotti's side had a bit of a flurry but Spurs still looking the more dangerous team.
Leicester 0-0 Brighton
James Maddison is now warming up. Please.
Everton 0-1 Tottenham
And the saves keep on coming!
We've already seen two top-notch pieces of goalkeeping at both ends of the pitch and Robin Olsen does ever so well to beat away Son Heung-Min's ferocious attempt.
This is a proper ding-dong tie.
Everton 0-1 Tottenham
After a crazy start, it's all gone a bit quiet at Goodison. Everton have come back into this but Davinson Sanchez and Toby Alderweireld are frustrating the hosts.
Sheffield United 0-0 Bristol City
Almost brilliant.
David McGoldrick hits a first-time curler from about 25 yards, it is up and over the head of Max O'Leary but always just doing too much and if drifts wide.
Leicester 0-0 Brighton

Image source, .I've gone full sleeping bag for the second half.
Leicester 0-0 Brighton
James Justin is some player, surely he'll be in the next England squad? He's playing on the left of a back three tonight but pops up in the centre of midfield and chips a beauty of a pass into the run of Ayoze Perez but Christian Walton just gets there first. Both men look in pain. Good keeping.
Everton 0-1 Tottenham
Everton's defence failed to turn up for the opening few minutes and Spurs took full advantage.
Leicester 0-0 Brighton
Dan Burn! Ooooh almost a crazy own goal as the giant defender swings to clear at the back post and sends the ball right across goal and a yard wide.
Sheffield United 0-0 Bristol City
Rachel Brown-Finnis
Ex-England goalkeeper on BBC Sport
Sheffield United have been doing all the right things, all the right build up play and they look synchronised - they just haven't executed well in the final third.
We didn't mention Rhian Brewster much in the first half but he did start well we just didn't see much else from him.
