Collin Quaner gets a bit of space on the right, cuts into the box and fires into the side netting via a deflection.

We couldn't see a goal, could we?

I'm not one to tempt fate but BBC Radio Leeds' Huddersfield Town commentator Paul Ogden drew up his penalty shootout grid on Saturday...

With the exception of a couple of the later subs almost every player on the pitch is running on almost empty now and if there's going to be a goal in the final 15 minutes you'd predict it's more likely to come from a mistake than anything else.

Players were getting treatment for cramp at half-time and water was being taken on.

Reading get us back under way for the 15 minutes of action in the English Football League season.

Still goalless at Wembley. Energy lacking. Penalties likely.

Close!

The ball breaks to Garath McCleary on the edge of the area, but the Reading man fires just wide of the mark with his left foot.

For a man of his quality, that was a real chance.

Two more minutes in this first period of extra time. At the moment I speak, Reading are just walking the ball round at the back...

I'd love to say both sides have a lot of attacking intent right now, but they don't.

Nothing of interest is happening, but Jordan Obita is booked for a poor tackle on Collin Quaner when the Huddersfield man looked to be getting away.

Two ball-playing options thrown on by the respective managers in Kasey Palmer and Liam Kelly.

Could their extra bite and freshness in the middle third add a telling contribution here in extra time?

Kasey Palmer nearly makes an immediate impact as he tries to thread a long ball through to Collin Quaner, but it is just out of his reach.

Then Reading winger Garath McCleary goes up the other end and fires high and wide.

The noise in Wembley is still as good as it was at minute one. They haven't tired, even if the players may have.

Reading's turn to make a change as Liam Kelly comes on for John Swift, who incredibly doesn't look very tired despite all that effort he's put in today.

One Chelsea loanee for another.

Huddersfield forward Izzy Brown, who missed that glorious early chance, comes off for Kasey Palmer, who has not played since 5 February because of injury.

Would you like to be a Huddersfield or Reading fan right now?

Reading are once again having much of the ball but not really doing much with it, as a ball into Yann Kermorgant is dealt with by Michael Hefele.

Gooner72: I cannot see anyone coming up from the Championship surviving in the top tier - a level or two below the standard required.

Jack Gilmartin: What a nervy play-off final this is now, that Brown miss right at the start could prove so crucial.

Mark Wilkins: As a neutral (Millwall) supporter I hope it's Huddersfield that make it through. It's been so long since they graced the top flight!

The legs are showing now as Reading midfielder John Swift turns a defender and looks to put the ball into two players in the middle but he trips over as he turns.

Huddersfield fans cheer, obviously.

Huddersfield win the first corner of extra time and Aaron Mooy plays the ball low into Izzy Brown, but the forward's flick is to no-one and Reading clear.

Tense and nervous.

Not sure there's really two other words in the English vocabulary to sum up the state of this.

Contrasting scenes with the two teams and their managers on the pitch.

Jaap Stam straight into his Reading players in the huddle to get his message across. David Wagner allowing his Huddersfield players just a bit more time to take on some fluids and compose themselves.

Extra time is under way at Wembley.

We needed a goal, because it would have opened the game up from a Reading perspective.

It's almost a containment plan from Reading, and Huddersfield have run out of ideas, they haven't got a way to break them down.

It's only the second time in 10 Championship play-off finals that we have had extra time - the other being Crystal Palace against Watford in 2013, which Palace won thanks to a Kevin Phillips penalty.

That's it for normal time. An extra 30 minutes to follow in this Championship play-off final.
