Advantage Huddersfield. Danny Ward, down to his left, keeps Sam Hutchinson's penalty out.

Here we go then.... Huddersfield going first...

So to penalties.

Huddersfield's last play-off game ended in a penalty shootout win over a team from Sheffield. The Terriers beat Sheffield United at Wembley in the 2012 play-off final to win promotion to League One.

Town boss David Wagner said his team had prepared for penalties but will that count for anything now the pressure is on? We're about to find out.

Owls fans chant "there's only one Keiren Westwood" and it's likely he or opposite number Danny Ward are about to make themselves a hero here.

Sheffield Wednesday have scored five of their seven penalties in all competitions this season.

Huddersfield have scored three of their five.

It counts for nothing now. Absolutely nothing.

Pats on the back for all of the players, especially the goalkeepers. We're almost ready for penalties.

Only 22 miles separate Sheffield and Huddersfield.

Only 12 yards will separate either the Owls or the Terriers from a place at Wembley.

We're going to a penalty shootout.

Huddersfield get a free-kick 30 yards from goal. Nahki Wells hits the wall.

Two minutes of extra time remaining.

It's fair to say Huddersfield have been the stronger of the two sides since half-time in normal time, but Wednesday have had their moments too in this second leg.

Perhaps penalties - the most unfair way to settle a football match - are the fair way to settle this tie.

Jordan Rhodes nips in at the near post to get a header towards the Huddersfield goal, but it's just wide.

Jordan Robinson: The Mrs is going nuts at this. She's a Wednesday fan and has an exam tomorrow! Put her out of her misery, Huddersfield.

Jamie Russell: I have no fingernails left. Come on Wednesday!

Deli Man: No nails left. Just toss a coin to send one of these to represent Yorkshire at Wembley. Missus mustn't read this.

Eight minutes of extra time to play.

Hillsborough is almost silent at times, its inhabitants gripped by the tension.

Wow. I thought Nahki Wells had scored for a moment. So did the Huddersfield fans, and their disappointment is audible when they realise his shot was into the side-netting, rather than into the corner of the net.

Two crucial last-ditch interventions from Huddersfield's rearguard mean we go into the last 15 minutes level.

Wednesday are back on top of this but it's starting to look like we could be heading for penalties.

Sheffield Wednesday are taking off Daniel Pudil, a full-back, and bringing on striker Atdhe Nuhiu.

Huddersfield were in the ascendancy and Wednesday had to survive that spell. They did survive that period without a goal.

David Wagner will have known, when you're on top you have to score.

Since then, Wednesday have come back into it and should have scored.

Into the second period of extra time now, with the prospect of penalties edging ever closer.

Former Owls goalkeeper Chris Kirkland has made his prediction. If he's right, it will see Jordan Rhodes - who has gone close twice in extra time - grab only his fourth goal of the season.

And that's half-time in extra time.

Michael Hefele's block from Owls forward Fernando Forestieri was a crucial one, keeping the score level with 15 minutes of extra time to play.

Wednesday are growing in confidence, but don't write off Huddersfield.

Huddersfield make their final change.

Rajiv van La Parra is off and Tareiq Holmes-Dennis, another left-sided player, comes on for the final 15 minutes of extra time.

Huddersfield survive another Wednesday attack, with Michael Hefele making an excellent block near his own line. One minute to add on.

Wednesday getting closer - now a top save from Danny Ward!

It's Jordan Rhodes again for the hosts, picking up the pieces in the box after Sam Hutchinson had won the ball back superbly in midfield for the Owls.

Goalkeeper Ward gets down low to keep out Rhodes' snapshot.
