Huddersfield look jittery here.

Luton work the ball well, with Harry Cornick finding Snodgrass.

The former West Ham and Leeds man shoots - it's not a great shot by any means but home keeper Lee Nicholls nervously pushes the ball out into danger, where Amari'i Bell stabs wide.

Danel Sinani, who scored Huddersfield's goal in the first leg, makes a pig's ear of a corner and Luton are let off the hook.

The visitors have shown more quality from set-pieces, and looked most likely to score so far.

Where's Pipa?

You've got to make sure your defensive duties are done first.

Great work from Lee Nicholls, he was in the right place to make the save, but we should be 1-0 down.

Harry Cornick has to score there for Luton!

Danny Hylton wins the ball high and Luton work the ball to Kal Naismith, whose low ball across the face of goal is asking to be slotted in.

However, Huddersfield keeper Lee Nicholls saves from point-blank range. Great reactions.

The first chance goes to Luton.

Again they go long - Robert Snodgrass then plays a lovely through ball for Harry Cornick, who drags his left-footed shot wide.

The angle was tough but the Hatters forward arguably should've done better, even on his weaker foot.

There's a clear tactic from Luton to get the ball forward quickly at the moment.

They're trying to put Huddersfield under pressure - and get Danny Hylton into the game - it's been a good start from them here.

Luton win a couple early corners, taken by veteran Robert Snodgrass - who is booed by home fans for his previous allegiance to Leeds.

The deliveries have quality but Huddersfield do their defensive job.

It's bouncing at the John Smith's Stadium, as it should be.

Huddersfield will be hoping to thrive - for Luton, it might be a case of whether they can survive a potential early onslaught from the hosts.

Right then, let's do this. Referee Peter Bankes gets things started.

Huddersfield have never won a home match in the Football League play-offs in nine previous attempts, while Luton are winless in all five of their EFL play-off matches.

Will one of those change tonight? It may well be a draw after 90 minutes, but we'll have a winner in the end...

Commentary teams from BBC Radio Leeds and BBC Three Counties Radio are in position at the John Smith's Stadium, with live coverage of this rather massive game.

You can't listen online, unfortunately, but if you live in either area tune in and absorb the atmosphere from West Yorkshire.

Former Huddersfield keeper Matt Glennon and ex-Luton midfielder Jonathan Smith are on co-commentary - we'll be bringing you some of their insight.

The adventurous thing for Luton to do from the start would be to put Huddersfield under pressure, and I imagine that's the way they'll go.

But at the same time it's important they keep it tight, and not give Huddersfield any encouragement.

Huddersfield have home advantage and plenty of successful play-off experience.

Luton's squad has been hit by injuries but Nathan Jones' side are as gritty as they come, and they love to upset the odds.

Some managerial Championship news in the past hour or so...

Championship side Reading have appointed former England midfielder Paul Ince as their permanent manager.

The 54-year-old had been in charge on an interim basis since February when Veljko Paunovic left the club.

The former Liverpool, Manchester United and Inter Milan player led the Royals to four wins and three draws in his first 11 games as Reading avoided relegation from the second tier.

I thought Carlos Corberan would have played Sorba Thomas tonight.

He's had such a good season and he works so hard even when he's not having a great game.

He feeds off the crowd and tonight is going to be a 'feed off the crowd' type game.

Yeah, he's been out for a little while but I think he could have started tonight.

Both managers have made two changes to the line-ups which began the first leg at Kenilworth Road.

Huddersfield bring in Pipa and Levi Colwill, while the Hatters have Danny Hylton and Robert Snodgrass in for Cameron Jerome and Henri Lansbury.

They also have 17-goal top scorer Elijah Adebayo, out injured since 23 April, on the bench.

Huddersfield: Nicholls, Pipa, Toffolo, Lees, Colwill, Hogg, O'Brien, Holmes, Sinani, Ward, Russell.

Subs: Blackman, Anjorin, Rhodes, Ruffels, Thomas, Sarr, Eiting.

Luton: Ingram, Bree, Naismith, Bradley, Burke, Snodgrass, Clark, Campbell, Bell, Cornick, Hylton,

Subs: Isted, Potts, Adebayo, Mendes Gomes, Lockyer, Kioso, Jerome.

Friday's first leg ended 1-1 at Kenilworth Road, with Danel Sinani's low finish for Huddersfield cancelled out by Sonny Bradley's volley from a free-kick.

Both sides had appeals for a penalty turned down in an exciting encounter.

Huddersfield should arguably have been awarded a spot-kick in the opening 10 seconds when Harry Toffolo was barged over by James Bree while trying to get to Ollie Turton's cross.

And Luton then had a penalty appeal of their own waved away by referee Robert Jones when Cameron Jerome burst through on goal and went down after tangling with Naby Sarr.

Huddersfield dominated possession as the Hatters tired in the second half, but both struggled to create clear-cut chances.

Four days, four finely poised EFL play-off semi-final second legs - what a week we have in store.

First up it's Huddersfield v Luton, for a place in the Championship play-off final.

The only guarantee is drama, whether that be within 90 minutes, extra time or - dare I say it - a penalty shootout.

I hope you enjoy the ride!
