Here's Aaron Mooy celebrating his penalty with Michael Hefele.

Huddersfield have eight minutes plus stoppage time to find a leveller.

It looks like it'll get nervy for the visiting fans.

Newcastle break away and have a chance to take the sting out of the game.

Dwight Gayle can't get past two defenders but is then found by Matt Ritchie.

Gayle gets to the byline and then blasts across the face of goal from a nigh-impossible angle.

Rafael Benitez makes his final change, bringing on DeAndre Yedlin for Christian Atsu.

The Ghanaian took his time coming off.

Huddesrfield are still dominating possession and looking for a way through the Newcastle defence.

The Magpies will have to keep their concentration, and try and take any chance they get on the break.

The home crowd at the John Smith's Stadium is urging on their team.

The second period has largely taken place in the Newcastle half.

Huddersfield deserve a goal back, as they have been asking all the questions in the second half.

They have a quarter of an hour to get an equaliser.

Midfielder Aaron Mooy sends Karl Darlow the wrong way from the spot, slotting in to the keeper's right.

It's very much game on now at the John Smith's Stadium.

Newcastle have brought on Yoan Gouffran for Jack Colback, who was on a booking.

Elias Kachunga goes down in the box under the challenge of Jonjo Shelvey - and referee Roger East points to the spot.

Newcastle striker Dwight Gayle makes a crucial impact - but in his own box.

He manages to block an effort from Isaiah Brown inside the six yard box after a corner was swung in from the left.

Huddersfield are pushing here, but still having no joy.

Wolves had centre-half Mike Williamson sent off as they slumped to their fifth successive defeat at Reading, with Paul Lambert's side now only one point above the relegation zone.

Wolves manager Paul Lambert told BBC WM:

"There was a few big decisions that never went our way, but I thought we played a good game.

"When you're down there and the little things go against you, you come through it.

"The lads know it, they know they're playing well enough to get out of it and it's not as if we look like a team that are struggling for form, we just need little breaks."

Newcastle make their first change, with Dwight Gayle replacing Daryl Murphy up front.

Gayle has been out with a hamstring and is now two goals behind the Championship's top scorer Chris Wood, who has 22 goals.

Meanwhile, Huddersfield have brought on Jonathan Hogg for Philip Billing in midfield.

Nahki Wells takes this one.

He swings it over the wall, but can't get it down quickly enough on the other side, and goes harmlessly over the Newcastle bar.

Huddersfield need to keep looking for a breakthrough and not get frustrated. There's plenty of time left.

Jonjo Shelvey goes into the book for a sliding challenge on Isaiah Brown.

He wins the ball, but chops down the Huddersfield man with a scissors action.

It doesn't stop Shelvey from giving referee Roger East an earful.

This is in a good position for the Terriers to strike...

Former Huddersfield keeper Matt Glennon on BBC Radio Leeds:

"Huddersfield are throwing everything at Newcastle but they need a bit of quality or luck to break down this Newcastle defence. There is still confidence in this Huddersfield side because they are still creating opportunities."

A great intervention at the back for Newcastle from Ciaran Clark.

Huddersfield ping the ball around but then, Clark touches away the crucial ball into the box.

The hosts have dominated possession since the break, but can't find a way back into the game as yet.

Huddersfield midfielder Philip Billing has another opening, as Nahki Well's header falls to him

However he miscues his attempted at a volley, and the ball bobbles wide of Karl Darlow's goal.

Huddersfield have started the second half well in the search for a way back into the game.

So far the visitors are dealing with what is being thrown at them.

Moments ago Newcastle forced a corner and Daryl Murphy made a nuisance of himself before Joel Coleman gathered and cleared the danger.

Newcastle cut out a cross from the left from Rajiv van La Parra and the loose ball breaks to Philip Billing.

He goes for goal again from range, but is well off target with this effort.

BBC Radio Leeds reports that Terriers keeper Danny Ward suffered a thigh injury in the first half.

It may have been in that clash with Daryl Murphy for the second Newcastle goal.

As a result, Joel Coleman is making just his second league appearance of the season.

He conceded five in the FA Cup defeat at Manchester City in midweek.

And straight from the kick-off, Newcastle centre-back Ciaran Clark chops down Isaiah Brown 30 yards from goal and gets shown yellow.

The free-kick from Aaron Mooy is floated into the box but goes out for a corner.
