James Chapman: Couldn't have managed it without the Stephen Warnock red but Derby v Reading has been a classic! Feed the Yak and he will score!

What is going on here? Stoke midfielder Glenn Whelan is shown a second yellow card for encroaching at a free-kick. He's off!

But hang on. The referee goes to consult with his fourth official and decides that in fact, he hadn't already booked Whelan, he stays on.

I'm not sure anybody really knows what happened there.

Reading have a man down, it's Simon Cox, but they are seeing the game out well. The Royals closing in on a place in the quarter-finals...

If you had money on a Josh King hat-trick today then all the best of luck to you. Blackburn cruising into the last eight, 90 minutes from Wembley.

That's Yakubu's first FA Cup goal for eight years. When he was 24...

"Yakubu does really well. Hal Robson-Kanu slips him in and as soon as it goes into him you know he is going to hit the target with a low shot, into the corner. That is no surprise to anyone. You may not get him chasing players down, but Yakubu will score you goals."

Yakubu! He's only been on the pitch for a few minutes but the veteran has fired Reading ahead! He stays onside, has no real pace left any more but shows good strength to hold off the chasing defenders and firing in a low left-footed shot.

His first goal in England since May 2012 - for Blackburn against Chelsea. You never lose it.

Andy, Sunderland: Wonder how Rob Zabrocky is feeling now after slating Josh King earlier? (see 15:28)

Rob Zabrocky: Just to capitalise on my mockers, Blackburn Rovers can't win the cup, England are rubbish at cricket and I will never win the lottery.

Crystal Palace make five changes to the side that drew with Newcastle in their last game. Defender Pape Souare makes his debut for the club while Scott Dann, Yannick Bolasie, Dwight Gayle and Fraizer Campbell all come in.

Mario Balotelli's goalscoring heroics against Tottenham have not earned him a place in the starting XI for Liverpool. He is on the bench, with Daniel Sturridge leading the line. Instead, Brendan Rodgers' two changes sees Joe Allen and Adam Lallana make starts.

Crystal Palace XI: Speroni, Kelly, Dann, Hangeland, Souare, Bolasie, Ledley, Ward, Gayle, Chamakh, Campbell.

Liverpool XI: Mignolet, Skrtel, Can, Sakho, Allen, Henderson, Moreno, Markovic, Coutinho, Lallana, Sturridge.

Into the last 10 minutes at Derby. Can the home side hang on for a replay?

Romance of the cup?

Joe: "After a rough last few months, my first love got me exactly what I wanted for Valentine's Day! Cheers for the special day Blackburn! #COYR"

Immsy: OK what did I miss? Was doing the house cleaning and switched off the TV, and Blackburn score four?!

Andrew Barnes: Stoke obviously couldn't do it on a cold afternoon in Blackburn.

It's not your day Stoke. Blackburn defender Shane Duffy gets away with a clear-cut handball in the penalty area. I doubt it would make much difference now.

"On the basis of what he have seen today, Josh King not having scored too many goals this season already has to be down to confidence, because he looks a top striker. He has run Stoke's defence ragged today, and they are a Premier League side. Stoke will be disappointed with their application but Blackburn have attacked this game. They're 4-1 up, but it could be more."

Former England captain Jimmy Armfield
BBC Radio 5 live at Ewood Park

"You have to give credit to Blackburn. They never gave into Stoke after going behind, apart from a little spell just after the goal. They've been the better side since then. They've settled down at the back, coped well with Crouch - who we said would be the danger man - and the pairing of Gestede and King has caused problems round the back. That threat has never been extinguished by Stoke."

Almost a brilliant goal for Blackburn! Craig Conway summons the spirit of Ricky Villa to dance into the penalty area from out on the right wing, he beats one man, beats two and just has the keeper to beat - but drags it wide! For a moment the magic of the cup was well and truly alive.

A little under two years ago Wigan were lifting the FA Cup trophy. This afternoon, they slumped to the bottom of the Championship as Blackpool are beating Nottingham Forest 3-2.

Elsewhere, Huddersfield have drawn level against promotion chasers Bournemouth, with James Vaughan making it 1-1 while Watford have battled back at Bolton, 2-2 there.

And another great chance for Reading at the iPro! Pavel Pogrebnyak has a free header six yards out but it's well saved by Kelle Roos. Jamie Mackie grabs the rebound - but fires wide.

Still 20 minutes left...

Almost five! Rudy Gestede is up to plant a header a the back post and Jack Butland makes an excellent save to push it away.

Jack Grant: Right Tim Sherwood. Task number one - get Darren Bent back to Villa Park!

Not sure he could if wanted to Jack. Steve McClaren has said there isn't a recall option, external in the loan deal.
