QPR are 20th in the Championship while Fulham are 18th in the Premier League
QPR were runners-up in 1982, as were Fulham in 1975
QPR 0-2 Fulham
Aleksandar Mitrovic is looking very, very tired out there now but at least he only has to go through the motions for another 10 minutes or so. Both teams look pretty spent energy-wise now.
Blackpool 2-2 West Brom
There's a break in play as Grant Ward receives treatment after picking up a knock.
He can't continue, and is replaced by Ethan Robson for Blackpool's fifth and final change.
Blackpool 2-2 West Brom
Chris Maxwell is at full stretch to keep out Kyle Edwards' low drive, after the West Brom substitute created a yard of space for himself just to the right of the Blackpool penalty area.
Seven minutes of extra time remain.
Arsenal v Newcastle (17:30 GMT)
Ian Wright
Former Arsenal striker on BBC One
It was a little worrying over the last couple of weeks, the way Arsenal were. I was asking Alan [Shearer] for tips on how to deal with being in that position in the table! But it has been a good turnaround - very, very good.
Although, it's a massive blow that Gabriel Martinelli has been injured. He gives Arsenal and Mikel Arteta that energy. To see him go down it was really quite worrying.
Burnley 1-1 MK Dons
The game is really opening up at Turf Moor.
Both sides look keen to land a knockout punch in the next eight minutes rather than take their chances in the penalty shoot-out.
QPR 0-2 Fulham
The final 15 minutes of this encounter are under way.
QPR are going to need to produce something quite special to turn this around now.
QPR 0-2 Fulham
Half time in extra time with Fulham on their way.
Arsenal v Newcastle (17:30 GMT)
BBC One
Amid the madness of extra-time in three games, there's live coverage of the 17:30 GMT kick-off between Arsenal and Newcastle on BBC One.
You can also follow it live on the BBC Sport website. Get stuck in...
Blackpool 2-2 West Brom
Both teams still appear to have plenty of energy left and the game is still flowing nicely from end to end.
Gary Madine is unable to meet a free-kick for Blackpool, and the hosts are able to clear their lines as West Brom take their turn to press forward.
Burnley 1-1 MK Dons
That was served up on a silver platter for Dale Stephens.
But the Burnley man drags his shot wide from 15 yards out.
He might have a penalty to take pretty soon from a similar spot. We go to shoot-outs if there is not a goal in the next 12 minutes.
Neeskens Kebano (105 mins)
Kebano smashes home Fulham's second
You wait 104 minutes for a goal and then two come along at once!
Fulham are firmly in control now and they work the ball from one side of the box to the other before Neeskens Kebano smashes in a drive at the near post.
Two goals from the substitutes. Scott Parker's changes from the bench have paid dividends.
Blackpool 2-2 West Brom
Off we go again!
Burnley 1-1 MK Dons
That is the half in extra time.
MK Dons boss Russell Martin can't issue any instructions. He was sent to the stands earlier in the match.
It is really chucking it down by the way.
Bobby Decordova-Reid (104 mins)
Decordova-Reid finally breaks the deadlock
We have a goal!
A move of quality produces the opener as Antonee Robinson does well down the left before crossing for Bobby Decordova-Reid, who plays a one-two with Aleksandar Mitrovic and then strokes a fine finish into the back of the net.
Blackpool 2-2 West Brom
Sullay Kaikai shoots over for Blackpool in first-half injury-time in extra-time.
It remains level, with just 15 minutes to go until we resort to penalties.
Burnley 1-1 MK Dons
Crtl-C, Crtl-V. It is another great save from MK Dons goalkeeper Lee Nicholls, who gets down really sharply to block Matej Vydra's near-post close-range effort.
QPR 0-0 Fulham
Close for Fulham as Bobby Decordova-Reid glances a header wide. QPR seem quite content to either try and snatch this on the counter or take the game to penalties. They have nearly everyone back defending.
Burnley 1-1 MK Dons
What a ping!
Ben Gladwin sets himself fully 25 yards from the Burnley goal, puts his laces right through it and thuds the ball against the upright with goalkeeper Will Norris beaten.
