The home side bring on two new players against the 10 men.

Romelle Donovan and Jordan Ayew are on for Ben Brereton Diaz and Tom Cannon.

Alex Neil makes a double change for Millwall.

Kyrell Lisbie and Lyndon Dykes make way for Crystal Palace loanee Romaine Esse and striker Mihailo Ivanovic.

Norwich's Paris Maghoma has hurt himself trying to stop Tyreece Campbell's run and has to make way.

A blow for the Canaries, he's added some creativity to the side today.

Sam Field, who was originally primed to replace Jacob Wright anyway, comes on in his stead. Wright remains on the field.

Ah.

Derby defender Dion Sanderson is shown a second yellow for stopping Femi Seriki breaking away over the halfway line after the home side clear a corner.

We've had almost 25 minutes of this second half but only really two Millwall attacks of promise to note.

Really tough stuff for both sides on a sodden pitch.

It's an unbelieve save from Grimshaw. You're thinking it's 2-2 and 10 seconds earlier Norwich could have put the game to bed.

Norwich just need to settle down and not let their levels drop to what Charlton's are.

Liam Kitching is booked for pulling back the rampaging David Ozoh.

The Derby midfielder is having a fine game today.

Tyreece Campbell has been the brightest for Charlton in this second half, getting possession and bursting up the flank to feed Charlie Kelman.

It's just the goal keeper in front of him but Norwich stopper Daniel Grimshaw doesn't make an error this time and does enough to deny Kelman a second.

And I guess you can't even go for a walk to relieve the stress, Josh. Good luck out there on a day like this.

Kalvin Phillips wide free-kick from the right causes the Derby defence some real problems but Japhet Tanganga can't keep his effort down as the loose ball drops to him 15 yards out.

Zak Sturge has space to try and pick out a cross out on the left flank...

But he slips on the wet turf as he makes contact and it flies into the travelling Millwall fans behind the goal. Sums up this second half so far to be honest.

Paris Maghoma cuts inside the box but his Canaries team-mate Oscar Schwartau has already decided to try and loft it in himself.

Wrong call. Ball goes whizzing into the stands.

I've really enjoyed Henrik Meister's work rate. Ok, not everything's worked out for him but the effort has been there.

It's really important we stay in the game now because Sheffield United are starting to knock on the door.

The first subs of the afternoon and it's a double change for Pompey.

Tyrese Shade and Ebou Adams are on for Ryan Kavuma-McQueen and Adrian Segecic.

Sammie Szmodics has a dip from long range as the home side struggle to get the ball clear.

The Derby forward makes clean contact but the shot flies narrowly over.

Tyreece Campbell's delivery into the box from a short corner is stunning and even though Norwich's Ruairi McConville gets to it first, he ends up banging it into his own net.

McConville puts his hands to head, disappointed to have let his side's lead slip but just as Charlton go to celebrate, the whistle goes. Charlie Kelman ruled offside.

A goal chalked off for both sides now.

Millwall work the corner in the air to Camiel Neghli on the edge of the box but his first time volley flies wide of the mark.

Finally a move of some quality as Millwall work it nicely through the midfield and down the right flank.

Camiel Neghli flashes a ball across the face of goal but it deflects off a blue home shirt and Pompey can eventually clear.

Moments later, Portsmouth block three shots in quick succession from Kyrell Lisbie, Jenson Metcalfe and Tristan Crama. That's more like it.

Delicately put, Greig.

The home side go to their bench.

Femi Seriki and Sydie Peck are on and off got Oli Arblaster and Hamza Choudhury.
