Full-time: Everton 2-0 Chelsea
It's Everton who progress to the semi-finals, and they have a former Chelsea star to thank.
For the Londoners, meanwhile, there is much to contemplate. They have been knocked out of two competitions in the space of a few days.
Chelsea are throwing everything they have at Everton, but it's a case of too little too late.
Goodison Park is bouncing and we've got four minutes of added time still to play on Merseyside.
Red card (Barry)
Gareth Barry trips Cesc Fabregas moments later and he too, receives a second yellow card.
He'll probably bump into Costa in the tunnel.
Red card (Costa)
It goes from bad to worse to ... downright miserable for Chelsea.
There's another flashpoint involving Diego Costa, who is fouled and then puts his head into Gareth Barry.
He is shown a second yellow and Costa takes Chelsea's hopes of rescuing this cup tie with him down the Goodison Park tunnel.
GOAL: Everton 2-0 Chelsea (Lukaku)
How can Chelsea respond to that magic from their former player? They have less than ten minutes to find a goal, and keep their season alive.
By the way, Lukaku has now scored in each of his five FA Cup appearances for Everton.
GOAL: Everton 1-0 Chelsea (Lukaku)
A moment of brilliance from Lukaku. The former Chelsea striker weaves his way past a number of players before delivering a pinpoint finish into the bottom corner.
That's the Belgian's 24th goal of the season and surely, it is among his best.
Less than 20 minutes to go now and we're still waiting for our first goal of the evening.
After the initial promise, this one has failed to catch light. Here comes a sub - Oscar is replacing a fellow Brazilian.
Surely the players will start to feel the pace of this game as the clocks winds down? It has been hectic stuff, even though there has been a distinct lack of quality.
Tiredness could play a crucial role in the outcome of this cup tie, as both sides look for a winning goal.
Right, we've played more than an hour at Goodison and it's still goalless, even though the game has livened up of late.
Both managers must be considering a change of two. Especially Roberto Martinez, who knows home advantage and Chelsea's mid-week woes ought to play into the hands of his side.
Diego Costa almost opens the score for Chelsea, after dancing neatly around the keeper - but from the tightest of angles imaginable, he sends his effort across the face of an unmanned goal.
That was almost brilliant from the centre-forward.
This game is crying out for a moment of inspiration, to be honest. Here's a reminder of who Chelsea have on their bench:
Begovic, Baba Rahman, Terry, Loftus-Cheek, Oscar, Traore, Remy
Howard, Stones, Niasse, Besic, Osman, Deulofeu, Kone
Everton come (relatively) close from a corner.
Funes Mori climbs to meet Cleverley's corner but his effort goes narrowly over the bar. Chelsea's goal remains intact.
The Everton fans at Goodison are trying to roar their team on to victory, but it's more of the same so far in the second period.
Is either side willing to risk losing this game in order to win it? Will tiredness take hold of Chelsea, given their mid-week game?
We're back underway at Goodison.
Let's hope for some more goalmouth action (and less arguing) in the second period on Merseyside.
Half-time: Everton 0-0 Chelsea
Lots of perspiration but minimal inspiration for either side at Goodison Park. The opening minutes hinted at an end-to-end game, but it hasn't really turned out that way, sadly.
Anyway, let's hope for better in 15 minutes' time.
The best moment of the half is provided by Willian, whose long range freekick is tipped over the bar by the Everton keeper.
The Brazilian has probably been the Blues' best player this season and his setpiece expertise could be crucial today.
Chelsea are now starting to assert themselves, with the likes of Pedro and Willian buzzing between Everton's defensive lines.
Cesc is looking to pull the strings, too, as the west Londoners push for a goal before half-time.
Oh, a sniff of an opening for the away side, as Pedro gets on to Cesc's through pass ahead of Robles.
However, the former Barcelona man can't keep the ball in play. Everton survive.
We're through 35 minutes at Goodison Park and there has not been a chance of note. In fact, the most eye-catching aspect of the game has been Diego Costa's fouling and falling.
Hopefully things will pick up slightly before we hear the half-time whistle.
Chelsea are struggling to string any passes together at the moment. They are simply being hustled and harried every time they have the ball.
Coming on the back of their Champions League loss, the Toffees might reason that they will tire as the game progresses, too.
The game is beginning to take shape after that frantic start.
Tom Cleverley takes a shot from distance that screws wide of the goal, but Everton are in charge of the game for the moment.
Still lots of huffing and puffing from both sides, but we're yet to see a great deal of quality.
Having said that, there is a really good zip about the match, which is encouraging the Goodison faithful.
The tempo of the match is really great to see. It would just be nice if some football was played by either side, rather than there being so much fouling and moaning.
