What an advert for League One.

For all Birmingham's class, they could not add to Willum Willumsson's clinical finish on 10 minutes and Mansfield made a triple-change at the break which changed the game.

Ryan Allsop was the busier keeper in the second half, but neither he, not the Blues wall, could prevent evergreen Lee Gregory from bending in a free-kick for Mansfield which earned a point it's hard to argue they don't deserve.

City extend their lead at the top, for a couple of hours at least. Mansfield look like they are in the promotion race to stay.

That's just the third time Birmingham have dropped points all season.

Bristol Rovers' Taylor Moore sees yellow and Reading have themselves a free kick.

Six minutes of injury time and Chesterfield almost have a sixth as James Berry's shot crashes against the bar.

Five minutes of time added on.

Salford make two changes with goalscorers Tyrese Fornah and Kylian Kouassi off for Francis Okoronkwo and Junior Luamba.

Feels more likely that Rovers have five minutes to get a draw than Reading to put it away.

Can the Gas rise to the challenge?

This could be a huge point if Mansfield can hold on, but we know Birmingham will have one more trick up their sleeve.

Play will have to be stopped for a head injury, I think we all need a breather.

THREE added minutes at Field Mill... plenty of time for a winner. But at which end?

Bristol Rovers are biting at the hosts now.

It's become less about damage control and more about snatching a point.

Got to say that's on Reading, who haven't really taken advantage of their extra man.

Oh, that's a chance for Salford to wrap it up.

Tyrese Fornah hares away down the left and crosses for Kylian Kouassi but in front of goal he can't get his feet adjusted and slides his shot well wide.

It has been a ragged second-half performance from Blues.

If you were sitting here as neutral and you were to say either team were going to pinch this, you would say it would be Mansfield.

Wow.

Bristol Rovers Clinton Mola almost has the chance to even the scores after turning a Reading defender and putting in a powerful strike.

Keeper Joel Castro Pereira has to make a diving save to keep it from becoming 1-1.

Despite it being 11 against 10, it seems to be the hosts who are feeling the pressure at the minute.

Derek Adams reacts to Chesterfield's fourth goal by making a change.

Gwion Edwards replaces Callum Jones and that's followed by Jamie Stott being cautioned for the home side.

Lee Gregory gets the wrong side of the Blues backline for a second and scrambles the ball to Hiram Boateng who in turn finds Will Evans to blaze an effort over the bar from the edge of the box.

A point is clearly not what either side want this afternoon. The intensity is off the scale.

Alex Cochrane's curling corner sails a foot past the far post untouched but straight from Christy Pym's long goal kick Will Evans is sent clean through on the Blues goal.

He isn't able to get the ball out of his feet allowing Taylor Gardner-Hickman, who had missed the initial kick, to recover and crowd him out.

Reading's Kelvin Ehibhatiomhan goes to ground in the box but the referee hardly blinks an eye.

No foul, no damaging penalty chance.

A change for Salford with Stephan Negru on for Ben Woodburn.

I would like to get at Bristol Rovers. We want to be a good team and good teams go in and are ruthless.

We need to defend the the set plays. They are probably Rovers' best chance of scoring now. It only takes one good delivery.

Ryan Allsop to the rescue again as Will Evans threads Stephen McLaughlin in down the left and another fierce left-footed strike is tipped over the top corner by Allsop's strong hand.
