A huge flag of Jim Smith is unfurled at one end of the stadium here to rapturous applause from both sets of fans.

Smith, who died in December, managed both sides who are fighting for a place in the FA Cup fifth round tonight.

Josh McEachran's game is over, he is being stretchered off.

The good news is that he was able to push himself off the ground and manoeuvre himself onto the stretcher.

Newcastle will want to get into the next round, will want to finish this game quickly but Oxford played extremely well at St James' Park, so it's not going to be easy. Steve Bruce has gone for a strong team and we should get a good game.

First shot on target for either side. Derby's Tom Lawrence has a crack from about 25 yards out but it's straight at Northampton keeper David Cornell.

Not looking good for Josh McEachran this.

He has barely moved, is needing to take oxygen and his left leg is being heavily strapped up in padding.

Under way at Anfield.

Birmingham midfielder Josh McEachran looks in trouble here, a coming together with Coventry player Maxime Biamou has left him in a heap on the ground.

The ref is doing a 'bring on a stretcher' signal.

Eastenders is finished. So it's time to turn on BBC One...

At the age of 19 years and five days, Toxteth-born Curtis Jones becomes Liverpool's youngest ever captain.

The Reds have a No 93 on the substitutes bench while the lowest numbered shirt in the starting XI is owned by 20-year-old Adam Lewis, who is wearing No 46.

Good stuff this from Coventry, livewire midfielder Zain Westbrooke flashing a 25-yard daisy-cutter narrowly wide of the far post.

Derby have their first chance now. Quick break and Jack Marriott fizzes a low shot wide.

Another Chris Lines chance, this time he blazes over the ball from inside the penalty area. Decent spell for the Cobblers.

First shot of the game as Northampton's Chris Lines has a crack from 20 yards but it goes wide. They thought it took a deflection. The officials didn't.

Coventry are on top at St Andrew's, seeing plenty of the ball in the Birmingham half but are yet to make Lee Camp work.

Meanwhile, Blues midfielder Jacques Maghoma breaks forward but smashes a shot way over.

That's landed in someone's back garden in West Bromwich.

It's taken nine minutes for Derby captain Wayne Rooney to get a touch of the ball. The game is passing him by because the ball is spending most of the time in the air.

Oxford United manager Karl Robinson may talk about "a free hit" against Newcastle United but there is a real mood of expectation around the Kassam Stadium.

These fans have enjoyed visits from Premier League opposition this season, with West Ham United thrashed 4-0 in the Carabao Cup before holders Manchester City won 3-1 here in a quarter-final that was actually much closer than the scoreline suggests.

Liverpool manager Jurgen Klopp can call into the dressing room during the FA Cup replay with Shrewsbury Town, says Under-23s coach Neil Critchley.

Klopp said he and his first-team players will not be at Anfield on Tuesday so they can observe the Premier League's inaugural winter break.

But Critchley said Klopp could call in with a message at half-time as he did during the Carabao Cup quarter-final defeat at Aston Villa in December.

"It was brilliant," said Critchley.

"Even though we were going off the pitch at half-time thinking, 'We've played all right there but we're getting beat 4-0', it creates that element of doubt in your mind about whether you are doing the right thing and if you need to do something different."

First chance for Northampton to create something but Nicky Adams' free-kick into the box is cleared by the hosts.

First real chance of the game falls to the visitors Coventry as Amadou Bakayoko is slipped in behind.

He spins and scuffs a shot at goal which is cleared off the line by retreating home defender Kristian Pedersen.
