Millwall definitely look more up for it the first few miutes of this second-half.

Camiel Neghli shows a neat bit of skill to nutmeg the ball through into the box and takes a shot himself which forces a save out of Vladan Kovacevic, to tuck it behind the near post.

Keshi Anderson is in full flight and Oxford's Michal Helik feels he needs to intervene at the expense of a yellow card.

We should be seeing some more changes soon. The game needs it. 10 minutes to go.

The urgency has been lost these past few minutes.

News I'm sure any Leicester City fans lurking on this live page will be pleased to hear.

Around 15 minutes to go, plus stoppages.

The players are back out from the changing rooms and the second half has got going.

One change each at the break and as Luke Cundle has gone off for Millwall, with Mihailo Ivanovic coming on in a front-two with Josh Coburn.

Norwich have also brought Mohamed Toure on for Mathias Kvistgaarden.

Having spent his luck on that foul against Terry Devlin that went somewhat unpunished, boss Matt Bloomfield decides to withdraw the booked Brodie Spencer.

Przemyslaw Placheta comes on in his stead.

The referee has totally lost it here.

He's booked Marlon Pack for a shoulder challenge but doesn't book Brodie Spencer for the foul earlier on.

Fresh energy is needed out there, they've put a real shift in have the Pompey players, they've got to give it everything, that's all they can do and hope they get that chance.

Referee Josh Smith won't be too popular around the Fratton Park ground this afternoon, that's for sure.

Having already drawn the dismay of the home fans, he's gaining yet more of the crowd's hostility as he books Marlon Pack for barging into Brodie Spencer.

The majority of Fratton Park are fuming.

Having been booked just minutes before, Brodie Spencer puts in a risky challenge on a driving Terry Devlin.

The home fans think this game has a chance of evening up but no. The referee lets it slide.

Will Vaulks picks up a yellow for that foul on Gustavo Caballero on the charge.

It's the only victory the Paraguayan can take for his hard effort as the ball ends up down the other end to see Pompey team-mate Andre Dozzell in the bad books for tripping up Michal Helik.

Is there going to be a sting in the tail for Norwich for not taking those chances?

I do think Millwall look tired, I don't think they're quite at it, I think Alex Neil will realise he has to freshen it up to get at this Norwich back line, that's not to take away from this Norwich performance.

Gustavo Caballero does some excellent work to earn a free-kick in the Oxford half.

Brodie Spencer just about keeps the ball in play only for the Pompey man to steal it away and drive forward, weaving around the crowd of swarming yellow bodies before drawing the foul.

Oxford have had a brilliant start to the second half and look much improved since the break.

The home crowd have quietened a little as Portsmouth try to find a way to regain their lead.

They still have some dangerous moments in attack but the longer this game goes on the tougher that task will become with a man less, Oxford look much more dangerous in attack this half.

'Off! Off! Off!'

Sorry Fratton, not this time.

Though Oxford goal scorer Brodie Spencer has earned a caution for his challenge on Terry Devlin.

Will Lankshear fires but sees his strike deflected out for a corner.

It's delivered to no great avail but it's not cleared out either to allow Stan Mills to flash a cross right in front of goal.

It's begging to be poked into the net but his team-mates aren't quick enough to recognise the opportunity.

Norwich on top at the break but crucially they've not managed to find the goal to give them the lead their dominance deserves.

Mathias Kvistgaarden, Jack Stacey and Kenny McLean have all had chances for the visitors although the scoreboard remains all square.

That's what we've been calling for, Brodie Spencer getting higher, extra bodies in the box, and it's all square now.

Oxford have got something to work off, they've got a foothold in this game with the goal coming so early, that's exactly what they needed.

Colby Bishop thinks he's been pulled back as he hits the deck in the penalty area but the referee waves away the Portsmouth striker's pleas.

And another one!

Ali Ahmed whips a lovely ball into the box which drops right to Kenny McLean but he can't quite get his foot on it as he jumps to volley into the net.

Anthony Patterson dives to his left and makes the save.

Millwall then go up the other end and almost score themselves as Camiel Neghli crosses in and Tristan Crama heads narrowly wide.

Matt Bloomfield makes two changes for his trailing Oxford side at the break.

Will Vaulks and Hidde Ter Avest are on for the second half.

Yunus Konak and Sam Long make way.
