Harvey Knibbs, returning to the Charlton side tonight, is the first player to get a yellow card at The Valley tonight.

Seconds later, Boro's Tommy Conway works half a yard and gets a snapshot away but Thomas Kaminski again is equal to it, making a good save with his feet.

Are Sheffield Wednesday threatening to pad out their lead at Watford or are the hosts fighting back?

Well, it's a bit of both!

Firstly, Imran Louza works onto Othmane Maamma's through ball but his strike goes wide of the mark.

Then at the other end, Bailey Cadamarteri drives to the wrong side of the post from Jamal Lowe's delivery.

This has been a watchable - if somewhat tense - first half so far.

Both Swansea and Portsmouth have pressed each other intently out of possession, while they've threatened on the counter-attack.

There's yet to be a real clear-cut chance for either side yet, though. Neither team wants to make the first mistake.

There has been some great play so far especially in wide areas.

They are getting in great positions and really causing Sheffield United problems.

They need to start taking their chances now. They don't want to end up regretting not taking them because they have had some good chances to go in front.

An in-swinging corner from the Sheffield United right finds Danny Ings at the back post but, completely unmarked, the veteran striker somehow heads the ball over the bar from three yards out.

Incredible miss, especially for a striker of Ings' calibre!

Southampton come close to making it three, but this time the effort is off target.

It cames from Albion being sloppy at the back again as Leo Scienza intercepts a pass and finds Caspar Jander, who shoots just over the bar from outside the box.

Pinball in the Charlton box and the ball eventually falls to defender Matt Targett but on his right foot the Boro defender drags his effort from 15 yards out on an angle into the side-netting.

Still goalless at Deepdale at the 30-minute mark.

It's all been Coventry so far with Preston seeing less of the ball.

Can the league-leading Sky Blues bounce back from their defeat by Ipswich?

Birmingham's Jay Stansfield has received some treatment on the pitch following a coming together, meaning substitute Lyndon Dykes is getting warm on the touchline early on.

Dykes, a former QPR striker, receives a good reception from the home faithful but will have to wait his turn this evening as Stansfield looks good to continue.

A couple of back-to-back chances come for Portsmouth up at the other end.

Josh Murphy sends a dangerous cross to Callum Lang - who is playing up front as striker today - but Swansea defend it well and clear the danger.

Moments later John Swift has a shot from distance but is effort is straight at Swansea keeper Lawrence Vigouroux.

Portsmouth have been knocking the ball around nicely in the last few minutes but Swansea have pressed well and are providing a tough challenge for John Mousinho's men to break through.

But the latest chance of the game falls to the Swans as Ronald sends a header towards the goal from a central position but his effort flies wide.

Another chance for the visitors!

The ball is fed into Josh Sargent but his left-footed effort from 18 yards doesn't quite find the corner and Michael Cooper makes a one-handed save low to his right.

A really dangerous cross from Callum Brittain almost finds Boro striker Delano Burgzorg in the middle but great defending from Charlton defender Lloyd Jones sees the ball go out for a corner, which comes to nothing.

That is a great save from Preston. Haji Wright had so much to do but Daniel Iversen has just made a fantastic save.

Coventry are pressing for the opener in a tight encounter against Preston.

Haji Wright lets fly from close range and draws a tremendous save from Lilywhites goalkeeper Daniel Iversen.

I think you have to just try to stick together. They will have spoken about that.

There will be difficult moments but at times you just need to slow the game down and stay calm.

Norwich so, so close to the opening goal.

Jacob Wright does well, and eventually the ball falls to Josh Sargent, whose acrobatic overhead kick is destined for the back of the net but is cleared off his own goal line by, of all people, striker Danny Ings!

Soon after, the ball is set back to Kenny McLean but his effort from distance is wide, unable to recreate the heroics he performed for his national team recently.

Norwich have started this one impressively, however.
