Will Norris comes out to palm away another Sheffield Wednesday ball into the Peterborough box.

But he's off his line and Callum Paterson tries a shot from close range but Dan Butler puts in a stunning block to deny him.

It's just not happening for the Owls at the minute.

Sheffield Wednesday are being let down by their end product at the minute.

They're hogging the ball, dominating Peterborough in their own half and they're having no difficulty getting balls into the box, but they just can't seem to hit the target.

Another promising attack comes to an end as Dominic Iorfa draws a foul.

Great defending from Peterborough's Ronnie Edwards.

Callum Paterson gets on the end of a long ball to the right and races into the box, leading to Edwards making a last-ditch clearance.

The Owls duly take their throw-in and win another corner, which is once again dealt with by the visitors.

Frantic.

Sheffield Wednesday are still peppering the Peterborough box with chance after chance.

Josh Windass forces Posh goalkeeper Will Norris into a save as they keep up the pressure.

Still no goals in this half, though.

Barnsley face off against Bolton tomorrow night at Oakwell in the second League One play-off semi-final second leg.

Both Barnsley boss Michael Duff and Bolton boss Ian Evatt are in attendance tonight.

I wonder what they think of tonight's encounter...

Another Sheffield Wednesday corner is swiftly dealt with by Peterborough.

The Owls could do with a goal soon and you can feel the tension at Hillsborough.

Ephron Mason-Clark tries to chip home over Sheffield Wednesday keeper Cameron Dawson.

But his effort sails narrowly wide of the target.

That's the first chance Peterborough have had for some time.

There have been so many corners in this second half, but Wednesday haven't been able to threaten the keeper from them at all.

Peterborough have been comfortable in dealing with them. They have minimised the major threats, bar that Lee Gregory overhead kick.

It gets the crowd up, but these opportunities are all for nothing if you cannot do anything with them.

Penny for Darren Moore's thoughts right now.

His Sheffield Wednesday side have dominated this second leg but their season will come to an end as things stand.

Just over half an hour remains of normal time for them to find at least two more goals.

Oof!

Lee Gregory picks up the ball inside the Peterborough box then attempts an audacious bicycle kick which is going in until Will Norris makes an outstanding save.

That would have been quite something. The momentum is still well and truly with Sheffield Wednesday.

At half-time I asked you to vote thumbs up if you thought Sheffield Wednesday would get the goals they needed to level this tie or better, or down if you thought Peterborough would hang on.

The results...

Another Sheffield Wednesday corner.

Barry Bannan sends it in and Michael Smith heads narrowly the wrong side of the top left-hand corner.

A goal would completely change everything. In the first leg, Wednesday went for Peterborough and the chances didn't go in.

It's been the opposite tonight. One goal will silence the crowd, it will completely flip the momentum.

They need to wait for a half-chance.

The fact that two defenders are coming on [Nathan Thompson and Dan Butler] at half-time doesn't quite tell you they're panicking, but it tells you what they think of the current state of play.

We're back under way at Hillsborough.

Is it going to be a nail-biter for Darren Ferguson's Peterborough?

Sheffield Wednesday need two more goals to restore parity. And you'd have to fancy them to do it if they keep up their momentum from the first half.

The visitors make a couple of changes at the break as Joe Ward and Harrison Burrows are replaced by Dan Butler and Nathan Thompson.

The first of the League One play-off finalists will be decided shortly, and we'll know the second tomorrow evening.

Bolton and Barnsley drew the first leg of their semi-final last weekend and their tie must be decided on Friday.

Well, Sheffield Wednesday are halfway to overturning the four-goal deficit and there's still 45 minutes to play.

Can the Owls get the goals they need to at least send us to extra time?

Give this post a thumbs up if you think they can and down if you think Peterborough are going to weather the Wednesday storm.

We'd also love to hear what your thoughts on that crazy first half in South Yorkshire.

Darren Moore is looking for direct football, he knows Wednesday will get the bodies forward, and they are hoping the gamble pays off.

It's got to be brutal football, they're not in the position where they can play fancy football.

That's what they have been in the first half, but can they keep that aggressive behaviour up? That's my only question.

But it's been all Sheffield Wednesday so far.

A fabulous first half comes to an end.

That couldn't have gone any better for Sheffield Wednesday, really.

Michael Smith's penalty and Lee Gregory's close-range finish have stunned Peterborough.

But Darren Ferguson's side still have a two-goal aggregate lead up their sleeve and have had their chances on the break.

A stellar second half surely awaits.

Oof.

Barry Bannan whips in a succession of corners and Sheffield Wednesday almost go three up just before the break as Michael Smith heads on target.

But Peterborough keeper Will Norris saves.
