Rafiki Said's curling attempt is on course for the net. It finds the City goalkeeper Brad Collins in it's way but the ball ends up spilling back into the box.

Adam Armstrong is about to get to it before Collins leaps to smother it.

A close call.

Reading have struck the frame of the goal for the third time in the second half.

Sub Jacob Brown swivels in the box and lashes a shot into the top of the crossbar.

When it's not your night...

Boro have reacted to going a goal down by bringing on David Strelec.

The Slovakia striker is just coming back from injury and many will be looking at him to try and cover for the injured Will Lankshear.

He will try to live up to the expectation as Neto Borges departs.

The Championship, eh?

You could scarcely ask for a greater contrast between the first and second halves. It's as if the players swapped shirts at the break.

Cardiff look ragged all of a sudden and West Ham are all over them.

That's like scoring a goal for me.

He's through on goal.

What a tackle.

Wolves have a massive chance to equalise as newly introduced substitute Rodrigo Gomes is barrelling into space.

Cam Pring comes to the rescue though with a brilliantly timed tackle. That was big from the defender! Could easily have been an equaliser.

Rona Kpakio comes on for Perry Ng for the hosts, who has been struggling for the past couple of minutes with a knock.

David Turnbull is also on in place of Calum Scanlon for Brian Barry-Murphy's side as they seek to shore the game up, still ahead by a goal.

Edvin Austbo shows his threat with a positive run down the left, cuts inside but drags his low, right-footed shot past the base of the near upright.

A tasty cross from Max Arfsten into the Wrexham box but it can only graze Riley McGree's head.

Surely, a goal has to come in this...

Edvin Austbo is coming on for West Ham, adding pace and trickery, with Manor Solomon making way.

This could have been 3-3.

Cardiff have gone to pieces at the back and a loose header breaks for Jarrod Bowen to take the ball on his chest and race in on goal but Nathan Trott is swiftly off his line to smother at his feet.

Wolves are turning the screw up in the Bristol City end to prompt the away support's encouragement but, again, they do absolutely nothing with their time in the final third.

One of the visiting fans behind the goal looked spellbound as he witnessed Scott Twine's goal in the first half. You can see why. He's not been treated to any kind of spectacle from his own side so far.

Down the other end go Cardiff and Perry Ng tests Mads Hermansen with a low shot which the keeper holds down to his right.

The traffic is one-way here and you feel if West Ham get one....

Manor Solomon spins and sees a shot charged down while Joel Piroe can't quite get on the end of another low cross into the box.

Jarrod Bowen has come to life since half-time and is flitting around a lot more centrally and the Irons are all the better for it.

Joel Piroe then unleashes a thunderous shot from 25 yards out, leaving Nathan Trott flat-footed, but the ball swings away from target and misses the post by maybe six inches.

This place now is a complete different stadium to the one that was so quiet for much of the first half.
