Joe Bryan was running at full pelt when brought down and contact from Ryan Nyambe may have ended his afternoon.

He's being helped off the pitch and cannot put any weight on is right leg. Blood stains on the sock around his ankle are a giveaway to the problem.

He's replaced by Zak Sturge.

The home side are having plenty of the ball in these opening minutes of the second half but Hull aren't giving them any decent sights of goal.

This is a big 35 minutes for both of these sides.

It's a double substitution for Plymouth as Matthew Sorinola and Malachi Boateng are brought on for Jordan Houghton and Victor Palsson.

The volume from the home fans has gone up a few notches as Derby make a positive start to the second half.

A ball in from the right almost gives Jerry Yates a sight of goal before the Lions clear.

A strong lunging challenge at the other end then sees Ryan Nyambe pick up Derby's second booking. Joe Bryan is still down after that stinging tackle.

And Cardiff are down to 10 men!

Out of nowhere Bali Mumba receives a flicked on ball and seems to be through on goal, only to be brought down by Dimitrios Goutas.

The referee shows Goutas a straight red card, and the home fans finally have something to cheer about.

Derby's turn to ask for a penalty.

Ebou Adams gets ahead of George Saville as he looks to shepherd the ball out for a goalkick.

Adams tangles with the Millwall man and goes down. No dice.

Looked a tight call but probably the right one from Elliott Bell.

A second Sunderland change, as Dan Ballard is forced off.

Chris Mepham is on in his stead.

Our friends at Sky Sports are reporting that midfielder Enzo Le Fee was forced off at the break with a hamstring issue.

Things decidedly not going the way of the hosts today.

The away side threaten an early second in this half.

Kyle Joseph has a shot blocked and Steven Alzate has a dip from just outside the area that beats the near post.

Home defender Dan Ballard is down after making that block and it looks like his afternoon is done.

A typical quirk of the fixture list means John Eustace's former side Blackburn are Derby's next visitors.

Rovers are reported to have asked for more away tickets for that one.

One change for the home side at the break.

Romaine Mundle is on for Enzo Le Fee.

The talented Frenchman just couldn't get into the game today.

There has to be better quality on the ball in this half.

Neither of the front men have given Derby anything yet, they have to get into the game more.

Rubin Colwill starts the second half well for Cardiff as he dashes down the left side.

He doesn't have any support, but the tackle from Nikola Katic gifts the away side an early set piece.

A short sharp rain showers hammers down over Pride Park as the players start the second half.

No changes for either side at the break.

The sides are back out and Plymouth's Callum Wright is taken off for Bali Mumba.

It seems boss Miron Muslic will be playing him much higher up the pitch than usual.

Argyle have to keep the ball and build through possesion.

I think they have to get forward a bit better and attack more with numbers this half.

They have to go and get it.

We're back under way in two of our lunchtime games.

But we'll have to wait a few minutes more at the Stadium of Light after those six minutes of first-half stoppage time.

If Sunderland are to retain their unbeaten home record, and (you'd have to think) any real chance of finishing in the top two this season, they're going to need to come back from behind in this one.

Hull will be desperate to cling on to three points, to build a bit of a buffer to the drop zone.

The home side made a bright start but the Tigers grew into it and took the lead when Anthony Patterson made a hash of Joe Gelhardt's corner and palmed the ball into his own net.

Ruben Selles' men have looked the better side since then but have lost on-loan forward Louie Barry to what looked like a knee injury.

Sunderland have yet to force away keeper Ivor Pandur into a save of note.

Big 15 minutes for boss Regis Le Bris.

Millwall have had the better of a scrappy first half, but neither keeper has had to break into a sweat.

The Rams have improved after a tough opening half-hour, but have produced little to get the home fans too excited.

Their wait for a first goal at home since Boxing Day goes on.

The home side are ending the half as they began it, firmly on top.

Dan Ballard gets first contact on a corner from the Sunderland left but he can't direct his effort on target.

About a minute to go before the break.

For me in the second half Plymouth have to be more progressive in the final third.

They can't get frustrated, it is still only 1-0 and although the crowd are getting annoyed they can't let that get to them.

All they need is one chance and they can be right back in it.
