Bluebirds remain one point above third-placed Fulham
Barnsley stay in bottom three after defeat at Nottm Forest
Blackburn promoted back to the Championship
Chesterfield relegated from the EFL after Morecambe draw
Bradford 0-0 MK Dons
The pitch looks absolutely dreadful in patches at Valley Parade, where it's a big night for visitors MK Dons in their bid to avoid the drop.
Much of the near side of the field is damp, muddy and squelchy.
Derby 0-0 Cardiff
No ding dong before kick-off between Gary Rowett and Neil Warnock after their snow-based tiff last month. It's all smiling and joking at Pride Park this evening.
How long will that last? Derby's Richard Keogh has the first chance of the evening, but his shot is blocked away.
Football is happening across the English Football League.
Your promotion dark horses
Sam: Don't forget about Brentford. The Bees aren't too badly placed for a late play-off push - especially if Millwall, Boro and/or Derby drop points.
The players are making their entrance across the country and kick-off is coming your way very soon.
Nottm Forest v Barnsley (19:45 BST)
Image source, GetBarnsley start the night two points from safety, ahead of what is their long-awaited game in hand.

Hosts Forest, in 17th - 11 points above Barnsley - are already safe.
Morecambe v Cambridge (19:45 BST)
Despite not playing tonight, Chesterfield could be relegated to the National League by 21:45 BST if a result goes against them.
The Spireites' seemingly-inevitable fate will be mathematically sealed if Morecambe were to avoid defeat at home against Cambridge.
Newport v Accrington (19:45 BST)

So we'll keep you updated on goings on at Rodney Parade throughout the evening.

Bradford City v MK Dons (19:45 BST)
Image source, Getty ImagesTonight, Milton Keynes Dons will be relegated to League Two if they lose and Rochdale win at home to Plymouth, or if they lose and Oldham avoid defeat at home to Southend.
MK Dons would also go down mathematically tonight if they were to draw while both Oldham and Rochdale won.
But a victory at Valley Parade would guarantee the Dons' survival until at least the weekend, if not longer.
Doncaster v Blackburn (19:45 BST)
Image source, Getty ImagesBlackburn Rovers could seal an immediate return to the Championship tonight, after one year in League One.
The Lancashire club will be promoted if they beat Doncaster, or if they at least match third-placed Shrewsbury’s result at home to Peterborough.

Derby v Cardiff (19:45 BST)
Image source, Getty ImagesGood evening. Are you ready for another potentially-decisive night of English Football League action?
Less than three weeks of the EFL season remain and three sides' 2018-19 divisional fate could be sealed this evening, while an already-promoted club could clinch the League Two title.
Plus, over a month since their meeting was controversially postponed because of freezing conditions, promotion-chasing Cardiff are back at Pride Park for an enormous Championship game against play-off hopefuls Derby, with the Bluebirds looking to go four points clear of rivals Fulham, who only have two games to go.
Sound fun? Aye, we agree. So let's crack on with the build-up to tonight's 12 EFL games, which all get under way in half an hour's time.
