BBC Sport's Ged Scott at Molineux: "The atmosphere is much changed on an emotional night inside a wintry Molineux. Lifted by their fans, and by the double substitution of Dicko and Edwards, Wolves have raised their game and deserve to be level."

As it stands, we're heading for extra time at Wolves and Chesterfield. West Ham are heading for Bristol City in the fourth round.

Hammers substitute Kevin Nolan catches Phil Jagielka late as the Everton defender clears and is shown a yellow card. This is bruising stuff.

That Wolves equaliser has been coming. Full-back Dominic Iorfa gets to the dead-ball line and crosses low for half-time substitute Dave Edwards to slide a shot past Marcus Bettinelli.

Nouha Dicko had slammed an effort against the crossbar moments before that - and it was beginning to look as if the home side's second-half pressure would go unrewarded. Now they can think about victory.

Wolves are making much more of a fight of this in the second half, and they could easily be level. Matt Doherty has just headed against the post from a corner, with a follow-up effort then cleared off the line. Nouha Dicko has definitely made a difference for the home side since coming on at the break, having seen a shot blocked seconds before Doherty was denied.

Andy Carroll is in the wars as he crumbles to the ground while challenging Toffees defender John Stones and keeper Joel Robles for a high ball. Duncan Ferguson, watching from the Everton bench, will have admired the West Ham striker's bravery. Another impressive performance by Carroll.

West Ham are trying to wrap this up early. Enner Valnecia's through ball to Andy Carroll is only just cut out before Aaron Cresswell goes close with a low drive. Everton's 10 men are firmly on the back foot.

Just a reminder that you can watch Enner Valencia's goal for West Ham now by using the highlights tab at the top of the page.

Everton boss Roberto Martinez needs a goal. He's sending on Kevin Mirallas and Bryan Oviedo. Ross Barkley one of those coming off. West Ham are looking comfortable.

Paul Collins:, external It's good to see Big Sam having some success. He's got West Ham playing good stuff in the first year he has been allowed to spend some cash.

Aidan Williams:, external West Ham will be happy with this, if they do win it is the expected result, a big compliment considering Everton last season.

As it stands, Bristol City will host West Ham in the fourth round while Fulham will be travelling to Sunderland. It's still goalless between Chesterfield and Scunthorpe. Still time for more twists and turns.

"What a crazy challenge. Mark Noble is coming across, Aiden McGeady slides in, late, leaves his right leg high and he clips Noble. His momentum takes him through and it is without a doubt a second yellow card. All of a sudden this game is sliding away from Everton."

A lucky escape for Doncaster's inexperienced 21-year-old keeper Marko Marosi. The Slovakia Under-21 international, a former Burnley College student, hits a clearance straight against Matt Smith's back, but the ball drifts wide. The striker follows that up by nodding wide from the impressive Jay Emmanuel-Thomas's cross. It may be tempting fate to say so, but at the moment, this tie is only going one way.

BBC Sport's Ged Scott at Molineux: "The snow is really falling heavily here now. The home fans on the South Bank have warmed up a bit though, having broken into a loud, uplifting rendition of Jack Hayward's Barmy Army."

It goes from bad to worse for Everton. Aiden McGeady, on a yellow from the first half, sends Mark Noble tumbling and is sent off. The Toffees will finish with 10 men.

Everton have now conceded in their last 11 matches. They haven't gone out of the FA Cup at the third round stage since 2007. They're got work ahead of them if they are to stretch that record.

Wolves have made two changes at the break in a bid to improve on a poor first-half display. Dave Edwards has replaced James Henry in midfield, while Nouha Dicko has come on in attack for Liam McAlinden - who probably had the home side's best chance in the opening 45 minutes.

Dicko makes a quick impact, striking the side netting from a tight angle after working the ball on to his left foot.

"Everton had the chance at one end and I said West Ham's best chance was on the counter attack. They swiftly come down the field and Carroll gets a turn, no pressure, weights a perfect pass to Valencia, it really is a nice team goal. Valencia's first touch is good, his second better and he rolls it into give West Ham the lead.

"John Stones has to be dealing with that situation and he will be disappointed he did not get a block on Valencia's shot."

First blood to West Ham. Andy Carroll rolls the ball into the path of Enner Valencia inside the Everton box but the West Ham man still has an awful lot of work to do. Despite the attentions of John Stones, Valencia makes space for himself before beating Joel Robles with an angled finish. Sweet.
