The Nottingham Forest fans are starting to leave. It was a great play from Poveda.
CJ Hamilton goes short, spins in behind Neco Williams. What a finish with his left foot, low past Hennessey. 3-0 and it looks like it's game over.

What a day this is turning out to be for Blackpool!
That's a wonderful finish by CJ Hamilton, drilling a first-time strike into the far corner.
Surely that's game over? Less than 20 minutes to go at Bloomfield Road.

Surridge has got to score, it is a huge chance for Surridge there. He has got to finish that. There is no doubt about that. It's a poor effort and Forest could have been back in the match.
Blackpool 2-0 Nottingham Forest
It's just not Sam Surridge's day today. Another chance goes begging as he shoots over from close range.
Steve Cooper sends on Ryan Yates for Billy Fewster.
Middlesbrough 1-3 Brighton
Middlesbrough send on striker Cameron Archer, who joined them on loan from Aston Villa this week. Can he inspire what would be a stunning comeback?

Another mistake again. It is a poor ball from Neco Williams who leaves Steve Cook so short. The feet are brilliant from Ian Poveda to draw the tackle in and its a great finish.

Brilliant play, Poveda makes his run into the box. He takes a couple of touches and passes it past Wayne Hennessey. Poveda does well to tuck it away.
Middlesbrough 1-3 Brighton
It is difficult to see a way back into this for Boro now.
Brighton look so composed and capable. They are managing this game superbly.
Ian Poveda-Ocampo (64 mins)
Cup upset very much on!

Good strike form Poveda, he takes it across his body and it just goes over the bar.
Blackpool 1-0 Nottingham Forest
Almost a stunner from Ian Poveda-Ocampo!
The space opens up for the Blackpool midfielder and he doesn't wait around, driving a powerful shot at goal which just rises over. I'm not sure Wayne Hennessey was getting to that.

Stephen Warnock
Former England defender on Final Score
The piece of skill from Mac Allister is confidence. It reminded me of John Barnes scoring a similar goal against Crewe. It's instinctive with the little Cruyff touch, he is a wonderful player.

It seems like the goal is coming. Dennis takes the shot and it's a great block by Ekpiteta.
Manuel Benson
Benson has his second! Burnley have a fourth!
Manuel Benson has been lively all game and he is alert to the danger Burnley have as they break. His run in behind the Cherries defence is picked out by Ashley Barnes and he makes no mistake with a lashed finish.
Bournemouth were back in it. Now they've been shoved down the mountain again.
