Terrific work from Tyreece Campbell sees him spin away from Tristan Crama, who takes down the Charlton winger on the run, and becomes the first man in the book.

Moments later, at the other end, Charlton full-back Kayne Ramsey is also booked for a similar challenge on Millwall winger Aidomo Emakhu.

Absolutely sensational, the team move was outstanding, from one side of the pitch to the other, the give and go, and Pereira with the driven effort across goal, giving Cummings no chance.

A brilliant team move from Leicester, and they now find themselves level, having controlled this second period so far.

The away side have the ball in the net but Callum Brittain's rebound is ruled out for offside.

Boro looking more dangerous this half though after a quiet opening 45.

The foul by Jannik Vestergaard which earned him that yellow card was on Matt Phillips.

The Oxford man can't continue and Luke Harris replaces him.

You have to go back to 1 January 2020 for the last time Middlesbrough won, or even avoided defeat at Deepdale.

Debutant David Strelec is right into the action for Boro as he sees a shot deflect wide of the post.

The second period is underway at The Valley with neither side making a change at the break.

In the first minute following the interval, Millwall's Camiel Neghli looks to find Josh Coburn in the middle but excellent defending from Amari'i Bell snuffs out the potential danger.

Surprisingly quiet around the Kassam Stadium.

Will Lankshear hammers an early effort over the bar and Brian De Keersmaecker fires wide.

There's a foul in the build up to that last shot and Jannik Vestergaard is carded.

The away side have made a notable change at the break.

Slovakian forward David Strelec is on for his debut in place of Kaly Sene.

We're starting to get back under way in our three lunchtime kick offs in the Championship.

Reminder that if you want to see how things are going in Leagues One and Two, you can do so here.

A double change for Leicester at the start of the second half,

Harry Winks and Ricardo Pereira are on.

Boubakary Soumare and Stephy Mavididi are off.

We're ready to go but referee Ben Toner hasn't reappeared for the second period yet!

Oh hang on, here is, nice of you to join us Ben...

I think the red card is harsh, the ball was cleared, yes, it was a foul, yes, it's a yellow but it's not malicious, he's caught him after with the follow through, very harsh indeed for me.

Leicester have been passive defensively.

Oxford have been quicker to the second ball, Ayew capitalised well for the equaliser and they're back into the game but moments but moments later it happens.

The Oxford players get right around the referee, at most it's a yellow, but it felt as though the referee wanted to give it and then it's the blow of 10 against 11.

The way they've defended and the way their shape is you can see how they've took three points against Ipswich and Leicester, it's going to take something special to break them down.

At the break, the home side hold a slender advantage.

Sonny Carey's right-footed half-volley separates the two sides in a half full of endeavour and spirit in South London.

Following an even first half hour, the home side found an extra gear and put the Millwall defence under sustained pressure before eventually finding the break through.

Will Millwall boss Alex Neil turn to his bench at the interval or leave it another 15 or so minutes? Stay with us for this one.

Conor Coventry's corner for the home side is a short one to Tyrece Campbell, but his centre has too much on it and that should be that for half-time.

Middlesbrough's 100% start to the season in serious jeopardy.

Lewis Dobbin gave the home side the lead with a fantastic strike and they're on course for a sixth successive home win against the Teessiders.

Eventful - Oxford lead.

Looking for their first league win of the season, Oxford were handed the perfect start with Will Lankshear's third league goal in four appearances.

The lead was brief as an awful back pass from Cameron Brannagan allowed Jordan Ayew to intercept and level.

The potentially pivotal moment arrived on 24 minutes with Foxes debutant Aaron Ramsey, having just tested Jamie Cumming with a stinging shot, seeing red for a wild tackle on Filip Krastev.

Przemyslaw Placheta thundered an effort off the bar before an unfortunate Boubakary Soumare own goal restored Oxford's lead.

The home side have a golden chance to nail their first three pointer of the campaign but have been given a warning with Stephy Mavididi running half the length of the pitch before seeing his shot saved.

Millwall's heads have not dropped since the goal.

An in-swinging corner from the left for the visitors is met by a diving header from skipper Jake Cooper but he is unable to keep his effort on target.

This match has suddenly burst into life.

Boro midfielder Hayden Hackney hits a shot wide as we head into three minutes of time added on at the end of this half.

The home side come close to a second just before the break.

Lewis Dobbin does well to squeeze the ball across the face of goal and Alfie Jones comes up with a vital block to stop Andre Hughes scoring from close in.
