Sheffield Wednesday win a free-kick right on the angle of the area on their left.

Barry Bannan sends it to the back post where Michael Ihiekwe heads wide under pressure.

He got up tremendously... Think he'll want that one back.

Joe Ward smashes a bouncing ball well over the bar.

The full-back had rather more luck when his effort in the first half deflected into the back of the net.

We're back under way.

What do Sheffield Wednesday do here?

They can not afford to go any further behind but they won't want to go into the second leg trailing by two.

For Peterborough, this is set up perfectly.

Ben Hewlett: I know everyone enters knowing the potential outcome, but there needs to be a limit. When you’re that much better over a season, the league above isn’t getting the best team, which is bad for the game. Look at Notts County - they could miss out on promotion despite finishing more than 30 points ahead of third.

Fat Sam's Disco: The play-offs are a rip-off. Teams should get rewarded over a season.

Dave Edwards: The play-offs always deliver drama.

Some strong words from Ben there... A Wednesday fan by any chance? The Owls finished 19 points above Posh in the regular season.

Wednesday have given the Peterborough fans opportunities to sing.

We said before the start that every Wednesday player had to be right on top of their game. It's a tale of two goalkeepers. Will Norris has kept Sheffield Wednesday out twice with those saves from Michael Smith and Josh Windass. At the other end, Cameron Dawson has made a right rick for Peterborough's first goal.

The next goal has to be Wednesday's. It's unthinkable that Peterborough would get the next one.

Peterborough will take that all day long, especially with the way we gatecrashed the play-off party.

A lot of people didn't expect us to be here and we're playing a team who finished 19 points above us, but here we are - it's 2-0.

The two teams are really trying to press each other because they know they're both comfortable on the ball. Posh are doing it better so far.

It's ALL going Peterborough's way so far.

It's been classic play-off stuff.

The away side had a great chance to open the scoring in the opening minutes but Michael Smith's shot was too close to home goalkeeper Will Norris.

Jack Taylor then put the home side in front when his low shot beat Cameron Dawson at his near post and Posh doubled their money through Joe Ward's deflected effort.

The Owls have kept their heads and looked to work their way back into it but Norris denied Josh Windass with a fine save.

Just not happening for Wednesday as a pass goes out of play under no pressure at all.

They need to get in and regroup here.

Into four minutes of time added on.

Can the Owls get back in this before the break?

Another opening for the Owls.

Michael Smith is left with time and space to measure a cross into the box and his centre is on to Josh Windass' head but it lacks power.

You feel like Wednesday might wish that was the other way around.

Good save from Will Norris to keep out Josh Windass' effort from inside the penalty area.

The Owls opened the home side up there.

They'll need to do more of that to get back in this.

Wednesday are shellshocked. They're in panic mode at the moment.

They've got to keep their composure on the ball, they can't just kick it everywhere. They'll get their chances, no doubt about it.

What a goal that is, Joe Ward. I didn't see that coming. He's got some backspin on it.

Goals always look more spectacular when they go in off the crossbar. Unbelievable.

I'll say this for Peterborough's commitment to passing out from the back, it must have their own fans on the edge of their seats.

Again they nearly play themselves into trouble before hurriedly hacking it away to the halfway line.

Sheffield Wednesday boss Darren Moore spoke about the expectation that is on his side to get out of this league.

There's a long way to go in this yet and he'll have been pleased with the reaction his men have shown to falling a goal behind.

Posh have been pretty comfortable. The only problems they've had have been ones they've created for themselves. There have not been too many alarms set by Sheffield Wednesday.

Darren Ferguson will be very happy. He's very animated today - and the players are sticking to their gameplan.

You often find that the first leg of play-off matches can be cagey affairs.

Nothing of it in this one, certainly not now Peterborough have opened the scoring.

The away side win a corner of their own and Callum Paterson manages to muscle free of his marker to get a shot at goal but it's blocked by team-mate Josh Windass.

I think that might well have been goalbound.

Moments later the Scot has a pop at goal that hits the top of the stand... Swings and roundabouts.

That was a terrible goal to let in. Cameron Dawson has been in fine form but he made a hash of the save.

Jack Taylor received the ball in the 18-yard box and sent in a shot with no real pace on it, but somehow it's almost hit Dawson's chest and crawled into the corner.

It's an awful goal to concede. This is a real test for Wednesday now. They left the backdoor slightly ajar and there was Taylor to score out of nothing.

I don't know if Dawson slipped but he didn't look comfortable. I thought he'd smother the ball but it went under his body.
