Three changes for Oxford as they chase the game.

Off come Cameron Brannagan, Stan Mills and Will Lankshear.

Ole Romeny, Yunus Konak and Nik Prelec are on.

Barry Bannan comes on to enjoy the fun, with Billy Mitchell taking a seat in the Lions dugout, while Patrick Roberts is on for the visitors for the final knockings in place of the very quiet Carlos Vicente and Marvin Ducksch replaces Jay Stansfield.

Of course Bannan is booed by the visiting fans, who remember his time, long, long ago now, at Aston Villa.

Millwall are effervescent.

The ole's ring around The Den as they pop it around and Kamiel Neghli and Mihailo Ivanovic exchange passes before Neghli opts to allow a cut-back from the right to run rather than having a first-time shot, which was the better choice, as there was nobody behind him.

The hosts are brimming with confidence again, however.

As it stands, they're heading back up to third in the Championship.

Tyrese Campbell is introduced for the home side.

Callum O'Hare gets the hook.

The changes are disrupting the flow of the game which Coventry will not mind.

Just under 15 minutes, plus time added on, to go.

Goalscorer Jack Rudoni is off for Coventry and Josh Eccles is on.

Also on is Ellis Simms for the first scorer, Haji Wright.

What a strong bench the visitors have.

Djibril Soumare takes a breather for Sheffield United.

Jairo Riedewald is on.

Another glimpse of goal for rampant Millwall as Kamiel Neghli lets fly but it's straight at James Beadle.

It's not about to get any easier for Blues... the fresh legs of Dan McNamara, Alfie Doughty and Tom Watson are coming on.

Ryan Leonard, Zak Sturge and Femi Azeez are the players heading off for a well-earned rest.

Femi Azeez whips in a corner to the near post where Mihailo Ivanovic has space but can only turn his header past the near post from six yards out.

Presentable chance, that.

Tatsuhiro Sakamoto cracks in a shot for Coventry and Michael Cooper makes a good save.

Sheffield United are under the pump a bit.

He's got his goal but now City sub Mathias Kvistgaarden has been subbed himself.

The Dane came on after nine minutes and departs after 63, along with Ali Ahmed, with Sam Field and Jakov Medic introduced.

Both goals were very preventable.

The defending was woeful. We played so well up until that point, to give away soft goals like that is very poor. Fair play to Coventry, they took the goals well.

I think we can conjure up more chances, but we need some fresh legs on the pitch.

So close for Oxford.

Cameron Brannagan sends in an excellent free-kick and Will Lankshear heads against the bar.

Ephron Mason-Clark has the assist for Coventry's second goal but his evening's work is over.

Not bad when you can bring on a man who has 10 goals this season - Brandon Thomas-Asante joins the fray.

That is indeed the end of Kai Wagner's evening. He's off and straight down the tunnel.

Fit-again Ethan Laird is on for him for the final 25-minutes or so.

Having made a crucial block at one end, Norwich's Kellen Fisher is denied by another at the other end, as his 20-yard blast is charged down by Liam Palmer.

A caution for Stoke skipper Ben Wilmot.

This game feels like it's on the edge for both teams.

Painful one for Blues' Kai Wagner as he goes into a full-blooded challenge with Ryan Leonard over a bouncing ball in midfield and looks to have damaged his shoulder in the collision. He'll need some treatment here.

Off we go for the second-half.

Oxford have brought on Aidomo Emakhu for Jeon Jin-Woo.
