What a chance!

Slick break from County as Nick Tsaroulla frees Tom Iorpenda down the right and he slides a perfect cross to the back post where Jayden Luker has the chance to repeat his strike which won the first leg, only to blaze this effort over Ryan Boot's bar from eight yards out.

Two controversial goals from Grimsby mean this game is going into extra time for yet more twists and turns.

Daniel Udoh thought he'd sealed it for Salford with a smart volley that made it 3-1 on aggregate but Grimsby fought back with goals that will likely have Ammies boss Karl Robinson very aggrieved in his post-match interviews.

Kieran Green's header looked to catch Jaze Kabia's arm as it went into the net, while Kabia's strike levelled the tie but the striker might have been offside.

So much to talk about. At least 30 more minutes to add more topics to list.

Luke Garbutt unravels a shot outside the box but it's directed straight into the Grimsby keeper's mitts.

Salford must have thought they had one foot in the final and two quick goals have stunned them.

They will have the upper hand should it go into extra time with that they've got on the bench.

County on the front foot early in the half as the visitors cough up possession in their own half, but Jodi Jones' low cross from the left is gathered by the sprawling Ryan Boot.

We go again.

As things stand the Magpies are 45 minutes from Wembley.

Chesterfield might have other ideas, however...

Oh. Six juicy minutes added to this second half.

If that's not enough for a winner, they will have whole lot more in extra time.

Salford need to calm this down.

They introduce Ben Woodburn in place of Josh Austerfield.

A couple of minutes left of the 90 and Grimsby want this winner while they are in the ascendency.

Charlie Vernam tries to find the trusty head of Kieran Green but a Salford man gets to it to clear it out of danger.

This game has sparked to life and we may just be getting 30 more minutes of it.

There's been a lack of quality from both teams. They have been guilty of giving the ball away but it's been fractious and that just leaves it on this knife edge.

We all know that one goal changes the complexion of this tie.

The only stat that really matters is the aggregate scoreline, which remains 1-0 to Notts County, but you'd imagine Paul Cook will be pretty satisfied with what he's seen from his side in the opening 45 minutes.

They have had plenty of the ball in the final third, they are just missing the final touch.

The Grimsby fans are really enjoying themselves now.

My goodness me!

Kallum Cesay aims for an immediate reaction to the leveller but sends his strike wide.

This game suddenly feels tense all of a sudden.

You can't take your eyes off this for a moment.

Chesterfield have played some really expansive stuff and arguably edged the first half, but remain behind in the tie.

James Berry has looked lively on the left and has sent a couple of efforts off target and seen another blocked, while at the other end Janoi Donacien has produced two huge blocks to deny Tom Iorpenda and Jayden Luker efforts on goal.

Neither keeper really tested yet, but it's a niggly, intense, 100mph local derby and I can't wait for half-time to end, to be honest.

A fourth shot of the half for James Berry, who collects a pass from John Fleck and fires in an effort from outside the box which he doesn't catch cleanly allowing James Belshaw to hold on low down.

John Fleck whips in a free-kick from the Chesterfield left but once again it's a great defensive header from County to clear their lines.

They'd held firm all night from set-pieces and long throws.

Another Grimsby change.

Jamie Walker makes way for George McEachran.
