Four more minutes to promotion for Birmingham City.

A possibly very tense four minutes.

Birmingham have a duo of chances to put the game to bed.

The first with Jay Stansfield, who tries his luck from distance on the counter-attack but sends it wide.

Then Luke Harris has a go from inside the box but his shot is nowhere near troubling the Posh keeper as it sails high and wide.

It looks as if time is running out.

Maths is not my strong point, but I do not fancy the ratio of stewards against the number of Birmingham City fans who may want to get on the pitch imminently.

It's turned into quite the battle in Yorkshire as Fred Onyedinma and a Town defender both have to scramble up from the ground to try and get on the ball in the Huddersfield box.

It's the Wycombe man who rises fastest but he can't get his shot past Terriers keeper Lee Nicholls.

Birmingham fans may need to hold their breath for the final whistle. A one-goal cushion doesn't feel like quite enough safety.

Harley Mills' corner travels across the box to Sam Hughes at the back post.

The defender connects well and heads it towards goal but the Blues keeper is wise to the move and palms it away at close range.

Three more goals to tell you about in League One and Two...

First, a third for Leyton Orient through Charlie Kelman, who drifted in from the left before unleashing an absolute pearler into the top corner.

Reece Cole has levelled for Exeter against Wigan. He meets a long through before shooting into the ground and seeing it bounce into the net.

Will Grigg has pulled Chesterfield level against Gillingham in League Two.

Blues unleash their top weapon. It's their highest scorer Jay Stansfield who is jogging on field to replace Alfie May.

While the hosts make an attacking switch of their own, withdrawing Ricky-Jade Jones for Gustav Lindgren.

Huddersfield are on the charge for an equaliser as David Kasumu curls in an attempt at goal from beyond the box.

It's a good one and is heading for the target but Sonny Bradley puts in a clutch block to keep it from levelling the score line.

You get the feeling Town are nowhere near done yet..

Alfie May tries for a second goal of the night soon after Blues make their substitutions but the Posh keeper is able to keep it out of his net.

Peterborough quickly respond by switching Malik Mothersille, Mahamadou Susoho and Carl Johnston with Cian Hayes, Hector Kyprianou and James Dornelly.

Three changes apiece then so far but whose will cause the most damage?

Mansfield are level again through George Maris, just past the hour!

He had just come onto the pitch before being found by a Lucas Akins pass before firing across Josh Keeley in the Orient goal!

And here they come...

Taylor Gardner-Hickman, Marc Leonard and a beaming Alfons Sampsted are off duty for the night.

Paik Seung-Ho, Keshi Anderson and Ethan Laird are the trio to enter the fray and what a trio of fresh legs indeed!

Chris Davies might want to make those Blues changes soon.

After a long string of passes from the visitors, Peterborough drive the ball up the other end to start a much more threatening attack.

It ends up at the feet of Malik Mothersille, who rifles a shot from the left of the box and requires the fingertips of Blues stopper Ryan Allsop to prevent it from reaching the bottom corner.

Big goal for Leyton Orient!

Charlie Kelman has put them in front at Mansfield. Jamie Donley's first time pass finds him on the edge of the area and he finishes brilliantly!

You sense that if Peterborough are going to get back into this game it is going to be now.

I am not sure Chris Davies will be entirely happy with how this second half has started, hence he is having a look at his bench, potentially readying a triple change.

Birmingham's Luke Harris is late to challenge Emmanuel Fernandez and earns himself the first card of the night.

Dale Taylor has put Wigan in front at Exeter, and it is from the penalty spot.

Maleace Asamoah Jr was brought down in the area.
