As you might expect West Ham are enjoying plenty of the ball, though they are struggling to break down the dogged Imps side, down to nine men remember.

Konstantinos Mavropanos has lashed a speculative effort from distance off-target while Arne Engels has seen a shot charged down too.

Nothing to split the two at the break.

Both have had opportunities, with Norwich twice sending one on target, but nothing spectacular yet.

Things looking rosier for John Mousinho at the break.

The Blades had a golden chance to go ahead when Patrick Bamford missed the target from Sydie Peck's cross and Zak Swanson made them pay with a rocket into the top corner shortly before the break, and there was still time for Hamza Choudhury to receive his marching orders for the visitors before the interval too.

Work for Chris Wilder to do if he is to stay unbeaten against Pompey.

Well the mood has changed drastically inside Fratton Park.

Earlier there was plenty of frustration but now a goal and a man up the Portsmouth fans are enjoying themselves.

The Blades are sat deep and defending for their lives at the moment.

To make matters worse for the Blades Hamza Choudhury has picked up two bookings in the space of nine minutes for challenges on Ryan Kavuma-McQueen, this latest a body check, and is sent off by ref Oliver Langford.

He sent two Blades off in the first half at Charlton last season, which Chris Wilder wasn't thrilled about.

Not sure he'll be on the Christmas card list this year.

West Ham are still lacking that urgency and zip in the final third to cut Lincoln open.

They need to score that goal.

Derby are trying to attack but it's just not happening.

In fact, Sam Szmodics concedes possession to allow a QPR attack. Alfie Lloyd has another shot swirling towards the target but once more Rams keeper Josh Vickers is in the way.

Goodness me that was a stunner by Zak Swanson.

The Fratton End sing "super Zak Swanson" after what is no doubt the best goal of his career so far.

Portsmouth have been good so far in this game and finally have something to show for their efforts.

They don't get much better than that.

And... release.

QPR can't do much with the corner and now are seeing Boy Kemper, who did good work to assist the opener, down on the ground requiring treatment.

He seems okay though and is going to continue.

The nine men win a throw on the left and Callum Elder hurls it in, with the ball eventually dropping to Ben House, who can't test Mads Hermansen in the Hammers goal.

Groans echo around Sincil Bank this time when the referee brandishes his red card for the second time.

Again there was absolutely no hesitation as Conor McGrandles was given his marching orders.

Arne Engels tries to add insult to injury from the 30-yard free-kick but his effort is well off target.

Surely this game is there for the taking for the Irons now?

Penny for Tom Shaw and Chris Cohen's thoughts? Two pennies, I guess.

Now it just gets harder and harder for Lincoln.

They've just got to regroup and probably get another midfielder on.

I wanted Lincoln to put West Ham under pressure, but it's going to be a tough watch now for 60 minutes.

Josh Vickers gets to Rayan Kolli's strike to tip it over for a R's corner.

Take a breath, Rams fans. You might need to hold it soon.

A brilliant cross in from Zach Abbott finds Finn Azaz but the left footed finish it not there and the volley flies wayward.

Azaz loves scoring against Norwich. In fact, he's never scored more against a team in English league football than he has with his four against the Canaries.

Down to nine men after 23 minutes.

It's a horror show for last man Conor McGrandles whose heavy touch on halfway is pounced upon by Jarrod Bowen who races through on goal.

The 31-year-old is surely too experienced to have reached out to tug Bowen back, but he does, and ref Andrew Kitchen has no choice but to brandish the red card for a second time in 20 minutes.

Ben House busts a gut to get back and double-up Jarrod Bowen on the right, with the England international's cross being deflected behind for a corner.

The set-piece is swung in to the back post but the unmarked Mohamadou Kante can only glance his downward header past the post from barely six yards out.

Not great defending, but poor finishing. He has his head in his hands.

The one thing that West Ham haven't got going at yet, which Lincoln have done, is attacking.

Joel Piroe hasn't got into the game yet.
