Much better from Birmingham as Jay Stansfield finds that bit of quality to play in Jhon Solis, who whips one towards goal but Hakon Valdimarsson saves.

Plymouth not really threatening a second comeback here. Five minutes left.

Two Ipswich changes as Tudor Mendel-Idowu and Daizen Maeda replace Jack Clarke and Kasey McAteer.

For Leicester, Harry Howell comes off for Will Alves.

Will either side find a winner or are we heading to penalties in this one? We're into the final 10 minutes.

Anton Stach goes close to his second goal against Nottingham Forest in the past four days with his first touch today but his 25-yard effort flies just wide.

And that's Sean Longstaff's last bit of action. Noah Okafor and Ao Tanaka come off too.

On are Anton Stach - who scored the winner here on Saturday - plus Harry Wilson and Brenden Aaronson.

It is all over at Doncaster where Championship side Middlesbrough ensure they progress without any kerfuffle, winning 3-1.

That's two of the 17 games tonight that have finished, with the majority of the others heading into the final 10 minutes.

Changes for Birmingham...

Alex Cochrane, August Priske and Jay Stansfield on for Kristoffer Lund, Kanya Fujimoto and Luis Vazquez.

Leeds' Sean Longstaff chops down Dan Ndoye and has a yellow card for himself.

Murillo coming on has sparked a bit of fightback. Terrific through ball for Dominguez to run on to. Forest got a corner from it. It looks better.

Well that strike by Valentín Castellanos should wrap things up for West Ham.

The away supporters have been signing his name ever since he came on and the forward ran into the crowd to celebrate with them after he tapped it home.

Just over 10 minutes of normal time remain for Southampton to find their way back into this game.

West Ham look to be heading into the next round at Southampton's expense as Valentín Castellanos makes it 3-1 to the Hammers.

An eyebrow-raising score at Watford, where the hosts are losing 5-0 to Peterborough.

Time is almost up at and for Doncaster, who are 3-1 down to Middlesbrough with minutes remaining.

A couple of Leicester changes with Olabade Aluko and Woyo Coulibaly departing for Wes Burns and Jayden Joseph.

Joe Edwards, who has just come off the bench for Plymouth, fouls Brandon Thomas-Asante and that's a penalty to Coventry.

Leeds don't really track the run of Nicolas Dominguez and his shot is tipped over by James Trafford.

Forest bring on four subs - Dan Ndoye, Callum Hudson-Odoi, Luca Netz and Murillo.

I understand wanting to keep hold of the ball and play out from the back but Leicester only seem to play themselves into trouble.
