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.

Changes for both sides.

Serbian international Mirko Topic is on for Emiliano Marcondes and skipper Kenny McLean is also off for Matej Jurasek.

Jed Wallace and Aune Heggebo are introduced for West Brom at the expense of Mikey Johnston and goalscorer Josh Maja.

That second goal for Watford came just moments after home goalkeeper Josef Bursik had denied Moussa Sissoko.

Whatever was said by Paulo Pezzolano at the break has had quite an affect on the visitors.

What have Portsmouth got in the tank to get back into it?

Right, we are getting started on the final half of the evening.

This is the only game not to have a goal. QPR and Oxford don't want to be the odd ones out, do they?

Joe Bryan nod towards his keeper goes awry and gifts Coventry a corner.

Millwall need to clear off the line but soon hear the reassuring sound of the whistle punishing their visitors for a foul in the box.

Relief for the hosts, who started so brightly but have nothing to show for it so far.

It's been all Millwall so far this half.

Coventry need a bit of a breather here, they need to regroup.

Millwall have begun this half resolute on testing Coventry's defence.

Lions defender Jake Cooper thinks he has a cheeky tap-in but Liam Kitching puts a foot out to deflect out for corner.

Coventry escape without a scrape after a meek delivery but need to withdraw Victor Torp.

On comes Jamie Allen.

An interesting start to this second half...

Josh Griffiths does well to keep his side in front.

Emiliano Marcondes is fouled on the edge of the box and the midfielder gets up to hit a wicked free-kick that the West Brom goalkeeper does well to stop.

An official time on that Watford equaliser from Imran Louza?

It took 27 seconds of the second half.

Incidentally, we questioned the introduction of Rocco Vata as an early substitute for Nestory Irankunda in the first period - he provided the assist...

The Watford leveller inside the opening 60 seconds of the second half meant I didn't get a chance to tell you they've also made two more changes.

Jeremy Ngakia and Nampalys Mendy are on for Caleb Wiley and Hector Kyprianou.

Billy Mitchell's welcoming back to the starting XI is christened with a caution for a late tackle on Coventry forward Josh Eccles.

West Brom are on target to end a three-match winless run.

It's a huge second half for Norwich.

A few times this season they've not started quickly enough after coming back out, they conceded in the 46th minute against Stoke and the 48th against Wrexham.
