Crawley opened the scoring with a stunning strike from Will Swan, but Wycombe responded and Daniel Udoh netted an equaliser.

It's all even at the break.

The League Two leaders, without a win in five matches, trail at the interval after Jamie Grimes' early goal for Chesterfield - who have had chances to score more.

Decisions incorrectly made on the ball is the story of this first half.

The Terriers are being met with some ire from the travelling fans.

Jon Russell's goal is the difference maker, he was allowed to run through on goal and his effort took a deflection before going in.

Jay Stansfield sends Birmingham ahead with a brilliant solo effort but should they be much further ahead?

Blues boss Chris Davies was vexed after complaints that Charlton goalkeeper Ashley Maynard-Brewer handled outside the box but saw himself receiving punishment for his protests.

With this performance though, not even an in-form Charlton look like they are going to pose a challenge to the league leaders.

Half-time at Oakwell and Barnsley lead Huddersfield in the Yorkshire derby.

Jon Russell's excellent strike from the edge of the box after 14 minutes separates the sides.

Town will be frustrated they are not level as, on two occasions, winger Tawanda Chirewa missed the target when presented with excellent opportunities to equalise.

As it stands, Huddersfield are set for their sixth league match without a win.

The Chesterfield fans regale Sunny Singh Gill with that ditty after the referee pulls up with a hamstring injury.

He was trying to keep pace with a speedy Spireites counter that would have resulted in a second goal for the visitors, if not for a fantastic last-ditch challenge by Harry Williams on Dylan Duffy.

Fourth official Karl Buckley takes the whistle - and a replacement fourth official has been located from the fans in attendance.

You can't look away for a minute.

Blues winger Keshi Anderson works the ball down the left and cuts it back for Willum Willumsson.

Willumsson sends in a curling effort but it swings inches wide.

Three minutes of additional time will close us out before the half-time break at Oakwell.

A terrific save from the goalkeeper.

Great work again from Stansfield, who just picked the pocket of the defender before playing in Iwata, whose effort is really well saved from Maynard-Brewer.

Jay Stansfield is going to be a proper handful for Charlton today.

He sets up Tomoki Iwata to unleash but he can't get past Addicks keeper Ashley Maynard-Brewer, who dives left to deny the midfielder.

Oh, Huddersfield will be kicking themselves if they are not at least level at half-time!

Tawanda Chirewa cuts inside from the right hand side and curls an effort to the far post but it doesn't quite bend enough and goes just wide.

Barnsley keeper Joe Gauci looked beaten there.

Boos echo around St Andrew's. Charlton are getting physical here and the home fans aren’t too pleased with referee Sebastian Stockbridge.

I think he and the officials were blocked for the Maynard-Brewer out-of-his-area handball but he’s letting a few more agricultural challenges go.

Charlton need to slow Birmingham down though, the home side are going through the gears.

Better from Walsall, as Jamie Jellis sends an effort wide of the far post with the outside of his right boot. The home fans then appeal in vain for a penalty after Ellis Harrison goes down in the box.

Crawley midfielder Kamari Doyle's nod at goal is denied by Chairboys keeper Will Norris.

Another chance for the visitors that goes begging.

Herbie Kane gets a strike off from a tight angle that is well gathered by Barnsley keeper Joe Gauci.

The Tykes wouldn't say no to half-time right now, you'd think.

Since our last League One update, Mansfield have turned it around and the Stags now lead at Blackpool 2-1.

Will Evans had levelled and then Keanu Baccus struck to give the visitors, who have lost their past seven games, the lead at Bloomfield Road.

Sonny Perkins has grabbed his second of the game to give Leyton Orient a comfortable 2-0 advantage over Lincoln City.

And Reading have taken the lead at home to Rotherham United thanks to Harvey Knibbs' goal.

A couple of goals to tell you about in the fourth tier.

Sam Foley has put Barrow 1-0 up at Cheltenham, while MK Dons lead 1-0 at Tranmere courtesy of Danilo Orsi's first goal for the club.

Birmingham midfielder Kieran Dowell tries a direct free-kick and it comes close, but ends up rattling the right post.

Blues are in full flow now.

Town are really knocking on the door!

Superb last-ditch defending from Barnsley's Neil Farrugia denies Ben Wiles from close range following good wing play by Tawanda Chirewa.
