Terry Devlin hits the side netting for Portsmouth.

How have they managed to get into this situation after dominating that first half?

Now that West Brom have gone to a back three the space is in the channels.

They have to make the most of that, but they've not done enough, especially from open play.

Watford have completely turned this game around after a really impressive start to the second half.

Fairplay to Rocco Vata who has had a hand in both goals for the Hornets after his substitution on in the first half.

Portsmouth now ring the changes as they chase an equaliser, the Fratton Park crowd is urging their side forward every time they are on the ball.

Charlie Taylor is injured for West Brom so on comes Toby Collyer.

Skipper Alex Mowatt also gets the hook for Krystian Bielik.

Norwich bring on Jovon Mokama and Lucien Mahovo for Oscar Schwartau and Kellen Fisher

A triple change from the Millwall bench.

Will Smallbone, Ryan Leonard and Macaulay Langstaff take the place of Billy Mitchell, Wes Harding and Aidomo Emakhu.

The hosts feel like they need some fresh legs to try and chase that elusive first goal.

Michael Frey, Sam Field and Karamoko Dembele depart to make room for Rumarn Burrell, Nicolas Madsen and Koki Saito.

No hat-trick for Haji Wright tonight.

He's taken off by Coventry boss Frank Lampard alongside Tatsuhiro Sakamoto and Josh Eccles.

Ellis Simms, Kaine Kesler-Hayden and Luke Woolfenden are on in their stead.

One change each.

Terry Devlin replaces Jordan Williams for Portsmouth.

Watford replace James Abankwah with Formose Mendy.

Dear me x2.

Alex Mowatt prevents Norwich taking a free-kick - yellow card again.

Sigh...

The first change of the night is a forced one as Oxford's Filip Krastev picks up an injury.

He's replaced by Siriki Dembele.

Dear me.

Samuel Iling-Junior is caught offside and kicks the ball away.

Out comes the yellow card - when will players learn?

It will be interesting to see if that goal will knock some wind out of Millwall's sails as they have been the better team.

It's a moment of quality from Wright, though.

We've managed to get a second look at that Watford goal which has put them ahead.

Josef Bursik makes a save from Moussa Sissoko and it then deflects of Rocco Vata and into the net - definitely one for the Hornets' substitute.

West Brom's Chris Mepham picks up a cheap yellow card for a foul on the halfway line.

Norwich are pushing hard for an equaliser.

Aidomo Emakhu once again is proving a danger on that left flank and sets up an attack in the box, which Coventry are able to clear.

Derek Mazou-Sacko is free to pick up the loose ball but thunders it above the net just before Femi Azeez is introduced to freshen up Millwall's attacking threat.

Luke Cundle is the one to make way.

You could forgive Portsmouth for being a little punch drunk after that double salvo from Watford right at the start of the second period.

Boss John Mousinho goes to his bench.

Adrian Segecic and Harvey Blair are on for Yang Min-hyeok and Conor Chaplin.

The home side can see they're having a lot more of the ball.

West Brom have allowed them to get up the pitch and that's got to be stopped.

It looks like they've opted for five at the back at moments tonight.

A big chance for Harry Darling to equalise.

Matej Jurasek's first touch is a beauty of a cross which the defender heads wide.

Aidomo Emakhu evades Coventry's defences to find a way through to goal.

He puts plenty of pace on his shot but Sky Blues keeper Carl Rushworth has a great line of sight on it and it heads straight into his arms.
