A consolation for Preston but a very nice goal indeed as North End pass their way through the Norwich defence and Josh Harrop is there to slide it into the back of the net.

Oxford United 2-1 Hartlepool United
Mark Sykes and Matty Taylor have both just come close for Oxford. Mitchell Beeney does well to pull off a decent save at the near post.
Can Hartlepool get a late equaliser?
Reading 2-2 Blackpool
Nathan Delfouneso is denied his second of the game and a potential winner as he brings Matthew Virtue-Thick's ball under control before firing at goal but Sam Walker is well placed to make the save.
Fulham 2-1 Aston Villa
Josh Onomah is coming off. 17-year-old forward Jay Stansfield is on for his Fulham debut.
Watford 3-2 Tranmere
Tranmere are pumped.
38-year-old Peter Clarke sees the Hollywood sign and has a go from about 30 yards out. It's closer to the corner flag than the goal but I'm going to give him credit for the sheer audacity.
Changes galore...
Leicester City make 10 changes to the side that won at Newcastle as they get set to host Wigan. There's a first start for Filip Benkovic.
Manchester United make seven changes from defeat at Arsenal for their trip to Wolves.There's no Anthony Martial or Marcus Rashford.
More on that to come shortly.

Will Vaulks' shot from distance is tipped wide as Cardiff ramp it up a notch in pursuit of a winner. They've got just over 10 minutes, otherwise they will have to settle for a replay.

Anyone ever scored two overhead kicks in a row?!
Alireza Jahanbakhsh goes for one again from a corner, but doesn't get quite as good a connection this time and sends it over...
Emmanuel Monthe (78 mins)
Oh noooo, what is the keeper doing?
Daniel Bachmann flaps at a simple corner delivery and there's a shot blocked, which ricochets into the path of Emmanuel Monthe, who turns and blasts it in.
GAME ON.

Fulham were beaten by League Two side Oldham Athletic in the third round last year. They are about 15 minutes away from the fourth round this year.
Southampton 1-0 Huddersfield
Southampton make their first change as goalscorer Will Smallbone is replaced by Stuart Armstrong.
Huddersfield, who now have top scorer Karlan Grant on the pitch, have been much better since going behind but not really created anything to worry Angus Gunn.
Fulham 2-1 Aston Villa
Fulham deserve to win this on the quality of their goals alone. That one from Harry Arter should count for two.
