FT: Bristol City 1-1 Swansea & Derby 3-0 Barnsley
Cardiff 0-0 Leeds
Leeds getting themselves into a bit of bother at the back.
A few loose passes invite Cardiff to pressure them and it takes evasive action from Joel Robles to help the Whites out.

Mark Hudson will be fairly pleased with the start. Still 0-0. Given the changes he has made, after a slow opening three or four minutes, Cardiff City are just starting to grow into the game a little bit more.
Euan Murray (og)
Hartlepool only made one change for this cup tie - and now they'll wish they'd made none.
Because the man coming back into the side, defender Euan Murray, has turned Josh Tymon's low ball across the face of the Pools goal into his own net.
Advantage to the Championship side.

Into the last five minutes here. Does either side fancy going for broke to spare everyone a replay?

Leeds continue to look the bigger threat.
Wilfried Gnonto sets up Darko Gyabi, who weaves past one challenge to move into the box before seeing his shot blocked.
Cardiff 0-0 Leeds
Crysencio Summerville required a bit of treatment after that foul on him but he is back on now and looks to be moving OK. Just a bit of extra spice to throw into what is a contest that already has plenty.

Yes the Leeds front four is inexperienced, it's young but it is lively, there is energy. There is a lot of talent there. There is the makings of a good team with Leeds.
Huge potential with the likes of Summerville, Gnonto, Aaronson and Gelhardt. Exciting players.
A couple of big chances early on at League Two grounds.
On-loan Stoke striker Douglas James-Taylor has the goal at his mercy six yards out for Walsall at Stockport but fires straight at keeper Ben Hinchliffe who, to his credit, makes a very good point-blank stop.
And it's a similar scenario at Hartlepool where Stoke's Josh Laurent is denied from close in by Ben Killip. Still goalless in both games.
Cardiff 0-0 Leeds

These are horrible conditions, with driving rain and a swirling wind.
The pitch at Cardiff City Stadium looks pristine, though, and it's Leeds who have certainly started brightest here.
Cardiff are the lowest scorers in the Championship this season with a mere 20 goals from 26 games, so you'd think their best hope of getting something out of this game is by containing Leeds and hoping for a low-scoring encounter.
Jason Knight
That is definitely game over now!
Nathaniel Mendez-Laing should score after getting in one on one. But his shot is parried back to him and he sets up Jason Knight to slot into an empty net.

Summerville was away, Sang was caught the wrong side. He gets a bit on the ball but he hacked through Summerville to get there.
Those challenges can be quite dangerous. It was a nasty challenge.
Cardiff 0-0 Leeds
The first booking of the game goes to Tom Sang for a naughty late dive in on Crysencio Summerville's ankle as the Leeds man looked to break away.

Better couple of minutes from Cardiff, they were able to get a bit of controlled possession.
Derby 2-0 Barnsley
Here is the goal that looks to have secured Derby's progress...
Barkhuizen's 'lovely finish' extends Derby's lead
Bristol City 1-1 Swansea
Save!
Bristol City have the bit between their teeth!
Nakhi Wells draws a fine diving save from Steven Benda with a shot from just inside the box.
Antoine Semenyo
Leveller!
Bristol City's renewed vigour in this half pays off as they keep an attack alive and send in a cross that Antoine Semenyo rises to head down and in.
Swans keeper Steven Benda should really keep it out, but the home team will not care.

Bright start from the Premier League team. Decent start from Gyabi and it just flashes past Alnwick's post.
Bristol City 0-1 Swansea
Bristol City are giving this a real go now... like they have much of a choice!
Cameron Pring beats a man wide left and fires a ball straight across the face of goal.

Leeds have come out meaning business.
Crysencio Summerville sets up Darko Gyabi on the edge of the box and the young midfielder curls a shot just past the far post.

Leeds' travelling fans are making a great noise at Cardiff City Stadium, belting out club anthem Marching On Together before kick-off.
Cardiff fans are struggling to make themselves heard.
