Solihull change as Leyton Orient loannee Callum Reilly is replaced by Joe Sbarra.

Really nice football sends the fresh-legged substitute Tristan Abrahams through, but his cross is headed away by Solihull defender Kyle Storer.

We start as we finished the latest period. With Solihull in possession and on top.

It's going to be about individuals, concentration and fitness.

One of these two sides will be a Football League team by 18:00 BST.

We go again.

Shots of both managers giving one final key team talk. Who can make the difference.

A look to the fans now. Very nervy nail-biting faces.

Solihull shaded that first period of extra time I reckon.

But they couldn't create that final opening.

No chances of note in the final minute.

We are on a knife-edge.

One minute added on.

Solihull have possession.

A foul in the box and Grimsby win a free-kick.

Solihull corner as we approach half-time in extra time.

Solihull skipper Kyle Storer is the latest to go down with cramp. But he's okay to carry on after a quick stretch.

And on the break, Solihull, once again, can't find that perfect final pass.

Tired legs out there.

Was that Grimsby's moment?

Jordan Maguire-Drew gets in behind but he can't find a team-mate with his cutback.

Last-ditch defending from Solihull.

He's had a good game, Gavan Holohan.

His passing has become sloppy as he's got tired but he's put in a shift.

Andy Smith is back on his feet and we play on.

Grimsby change. Gavin Holohan comes off. Tristan Abrahams comes on.

Attacking switch.

Grimsby's Andy Smith is down with cramp.

Play has stopped.

Joe Sbarra is getting a lot of joy down the left. He cuts on to his right foot but his latest curling effort is straight at Grimsby keeper Max Crocombe.

This extra-time period feels very extra-timey.

Tense.
