Harrogate have only had one effort on target in the 80-plus minutes we've played. It's all that counts, though.

Now Sam Folarin goes down in the box with a challenge from Eoghan O'Connell.

A big shout from Harrogate, but there is no penalty given.

Since James McClean has come on for Wrexham, he's put in three quality crosses and nobody is anywhere near it.

Another fine cross from Ryan Barnett from the right.

Another miss - this time it's Modou Faal whose header goes over.

An attacker for a defender for Wrexham as Modou Faal comes on for Tom O'Connor.

We are not far off desperation stakes for the Welsh club.

10 minutes plus change left.

This is non stop pressure from Wrexham.

Harrogate are really being pushed back.

Dean Cornelius has been exceptional in this second half, he's getting stronger as the game goes on.

Ellis Taylor looks absolutely shattered and I think that shows you the defensive work they are having to put in.

Wrexham sub James McClean enters the book for a foul on Ellis Taylor.

Not the first time that has been written throughout his career!

James Belshaw to the rescue for Harrogate again!

Andy Cannon nods one down for Jon Dadi Bodvarsson and the Iceland striker meets it with an acrobatic volley from eight yards that is instinctively saved by Belshaw.

Great reaction stuff from the Harrogate captain.

Just over 15 minutes plus stoppages to go.

Another Wrexham chance comes and goes.

Another fine delivery from Ryan Barnett from the right. James McClean arrives at the far post but his glancing header is badly off target.

Is this one of those days for the team sitting second in League One?

Now it is Simon Weaver's turn to turn to his bench.

He sends on Sam Folarin for Josh March.

We are tipping past the 70-minute stage and the League Two side still lead.

Substitute Junior Dixon blazes over for Boreham Wood before Ethan Galbraith converts his effort beating Nathan Ashmore as Orient progress by the skin of their teeth, narrowly avoiding a major upset at Meadow Park.

Fine midfield play from Dean Cornelius as he bursts over halfway.

George Dobson takes no chances and brings him down. An easy call to book the Wrexham man.

Orient win the shootout!

Paul Mullin, with clever play, lifts the ball into the path of Jon Dadi Bodvarsson in the box.

But the debutant and ex-Bolton forward, who signed as a free agent last week, hits the top of the stand with his first-time effort.

But at this ground, that's not that far over the top of the bar!

Ollie O'Neill is second up for Leyton Orient but his effort is saved well.

Josh Hare scores Boreham Wood's first penalty before Darren Pratley converts his effort confidently to make it 2-1 for Orient after three each.

Ollie Rathbone does a lot of work, he's a busy player.

But Wrexham need something a little bit different and a little bit of magic

A crunching challenge from Josh March on Max Cleworth and that sees the Harrogate man become the first player into the book at the Exercise Stadium today.

Phil Parkinson has seen enough as we hit the hour mark and he turns to his bench to make three alterations.

Elliot Lee, James McClean and Jon Dadi Bodvarsson are summoned with Ollie Palmer, Ollie Rathbone and Seb Revan making way.

Tom Whelan is first up for Boreham Wood in front of the travelling Orient fans and his effort is saved by the impressive Josh Keeley!

Diallang Jaiyesimi goes first for the O's and he confidently buries his spot-kick.

Chris Bush then hits the bar for the hosts!

The visitors have had a couple of big chances already in this second half, but crucially no goal.

Now Stephen Duke-McKenna fancies his chances at the other end as he cuts in from the left, but his shot is a couple of yards wide.
