The half-time whistles have sounded around the EFL.

Here is what's happened in the first 45 minutes up and down the country...

Fraizer Campbell is through in the area but is tackled well by Jordan Williams as he takes aim, moments after Campbell has a flicked header go just wide from Juninho Bacuna's cross.

Huddersfield could have done with that going in just before the break.

No real chances of note for either side down at The Valley since those couple of quick goals.

Charlton have been on a rotten run of late, sliding down to 19th after a run of one win in 14.

They have not been helped by injuries, but it seems a long time ago since the Addicks were the early pace-setters in the Championship.

Baggies forward Hal Robson-Kanu has just been involved in a bit of a wrestling bout with Charlton defender Tom Lockyer, earning both players a yellow card.

Leeds have had almost 70% of possession in the first half at Elland Road but aren't creating much.

They've got a wall of Owls in front of them.

Five minutes until half-time.

Swindon Town are without top goalscorer Eoin Doyle today - and, indeed, for the rest of the season - after follow promotion hopefuls Bradford City recalled the striker from his loan with the Robins earlier this week.

His absence isn't causing too much of a problem so far for Swindon, however, as Rob Hunt's goal has put them in front against third-placed Crewe Alexandra.

As for the Bantams? They're behind at Crawley Town... despite having thrown Doyle straight into the side.

Derby are pushishing for the leveller.

Martyn Waghorn bears down on goal but is denied by Boro keeper Aynsley Pears after some good passing play.

Jay K: Leeds need a proper striker!!!! So many chances and no reliable 25 goals a season man. Need this now and next year!!

Leeds still look the more likely to score, but it's not a great game at Elland Road.

Patrick Bamford's header has just been ruled out for offside. 30 minutes gone.

Leaders Wycombe are having a nightmare first half at the Stadium of Light. They're now 3-0 down with Chris Maguire just adding Sunderland's third from the penalty spot.

Elsewhere, Portsmouth are leading AFC Wimbledon, Ipswich are 2-0 in front against Accrington and Coventry still lead MK Dons thanks to a first-minute goal.

As it stands, Rotherham will be going top on goal difference - they're 1-0 up at Oxford United.

Barnsley still lead but Huddersfield with a decent chance to level.

Christopher Schindler attempts a half-volley from 10-yards but does not make clean contact with the ball.

Leeds almost break the deadlock!

Kalvin Phillips sends in a pinpoint cross and Jack Harrison volleys just wide.

It's been a quiet start in the fourth tier, with just three goals across 12 games in the opening 20 minutes.

The most significant of those goals has probably come at Cheltenham Town, where the fifth-placed Robins lead Walsall.

Mansfield Town and Salford City are also in front.

Still goalless in the Potteries, as home defender Danny Batth just fails to get on the end of an inswinging corner from James McClean.

Some early goals at the top of the division.

Leaders Wycombe trail 2-0 at Sunderland, Sam McCallum scored in the first minute to put Coventry in front against MK Dons, and second-placed Rotherham have just taken the lead at Oxford United.

As things stand, the Millers would go to the top on goal difference.
