Some frustration creeping in around the stands at the Riverside.

Boro were well on top of this game but did not make their dominance count.

And they should be level.

Aidan Morris's cross finds Leo Castledine in all sorts of space on the edge of the six-yard box - but he puts his header over.

If he hits the target he probably scores. Big chance missed.

Blackburn may be trailing in this six-pointer but they are the ones clinging on to keep the score down at the moment.

It's all Oxford. But can the U's put this game to bed? All the while it's only 1-0 and all that...

We are really just pushing Blackburn, a high pressure press. We are going to cause them to make mistakes.

That should be that, Preston look well beaten. Don't give them anything now to try and get back into this. A first goal of the season for Matt Grimes but he looked comfortable slotting that one in.

Chris Davies has turned to his bench for the first time, he wants that second goal.

Demarai Gray and Jonathan Panzo are on, with Ibrahim Osman and Ethan Laird making way.

Well this will be interesting now.

Aidan Morris has a shot blocked as Boro go in search of an immediate equaliser.

I was going to tell you before that goal, there's been a whole host of changes from the bench.

Jeremy Sarmiento and Leo Castledine are on for the hosts, while Nathan Jones had thrown on Tyreece Campbell, Lyndon Dykes and Kayne Ramsay for the Addicks.

A great impact for the visitors, though none of them were actually involved in the goal.

Chance to well and truly seal this for Coventry.

A tad soft? Maybe.

Matt Grimes swings in the corner and it's creeping towards the near post... and just hits the top of the crossbar! Audacious attempt if he meant it from Grimes.

Coventry straight on the front foot and Brandon Thomas-Asante has a shot from range after 18 seconds deflected behind for a corner.

The second half resumes at the CBS Arena. Coventry are eight points clear at the top with Boro trailing Charlton and nine points ahead of Millwall in third as things stand.

Whisper it quietly, but Sheffield United are only five points off the play-off places as things stand.

It will be a big win if they can hold on at Carrow Road. They're coming under plenty of pressure.

Sheffield United are having to do some serious defending. It's the Blades skipper Japhet Tanganga who gets there again for the visitors to clear a dangerous looking cross with his head.

I don't think this is high tempo enough still from Saints.

We are putting crosses in but they aren't good enough. We aren't taking enough risks, this is a really strange game.

Marvin Ducksch shoots just wide for the hosts.

Surely one of these is going in at some point.

Ohh, Myles Peart-Harris, was this the chance to seal it for Oxford?

Peart-Harris races towards goal but his finish is tame and straight at Blackburn keeper Balazs Toth. Either side and it's 2-0.

U's striker Will Lankshear was waiting for a tap-in as well and lets his team-mate know what he thinks.

Stan Mills hits the corridor of uncertainty with a lovely teasing ball into the box for Oxford and it's cleared behind for a corner.

Ciaron Brown then meets the set-piece for the U's but heads over from close range.
