Five minutes added time at St Andrew's.

Kwame Poku flashes an effort wide for the visitors - what a return from injury that would have been.

Ellis Simms bundles his way forward and gets on the end of a clipped ball over the top.

He manages to get the shot away but it's well blocked by Odel Offiah for Preston.

Five minutes added on for Boro to find a way through.

Can Oxford see out what would be a huge three points in the relegation battle?

They've got four minutes of stoppage time to survive.

Time is ticking down for Boro but it's relentless pressure from the hosts.

Leo Castledine has been heavily involved since coming off the bench and he has a shot blocked before collecting, side-stepping the defender and sending a left-foot shot goalwards.

But it's straight down the throat of Will Mannion for an easy save.

Hayden Hackney then forces a save from the Charlton stopper, again it's straight at him.

Into the 90th minute.

Four minutes added on.

Preston won just one of their final 15 games last season.

They're on track for one win from 12 here.

Deja vu?

I think we just need to get the ball forward and dig in deep. I think we have that in our locker. You look at a lot of teams and you know they don't have it in them. This Oxford side have it in them though.

Norwich are on track for a 12th league win in 21 games since Philippe Clement took over as boss in November (D3 L6). They will have picked up 39 points in that time if they hold on here.

The Canaries won just two of their opening 15 matches under Liam Manning (D3 L10), gaining only nine points in that time.

Quite the turnaround this season.

A warning sign for the hosts, this Saints side will carry danger to the end even though they've been below par tonight.

West Brom concede a soft free-kick and it's whipped in by James Bree.

Taylor Harwood-Bellis gets to it but puts it agonisingly over the bar. He's screaming for a corner but it goes the Baggies' way.

Still a bit of time to go in this one.

Wow, an almighty scramble in the Oxford penalty area and somehow the U's keep it out. Blackburn want a penalty but they're not getting one.

Blackburn trying to apply a bit of late pressure. They send in a corner form the let and it's cleared to the edge of the box.

Taylor Gardner-Hickman chests it down and tries the ambitious half-volley but it deflects behind.

Charlton are really riding their luck, here.

Leo Castledine misses his second free header since coming on for Boro, putting it over the bar again.

Seven minutes plus added time for Boro to find something from somewhere.

Matt Grimes has had a lot of space tonight, I thought Preston would try and close that down more than they have. He is making some fantastic runs, it is good to see from him.

Oof, the away end goes up but it's hit the side-netting for Sheffield United.

Tom Cannon meets a corner and his header grazes just wide.

Then at the other end, Adam Davies is off his line quickly to thwart Jacob Wright who had been slipped in behind.

Will we have a winner late on?

Another chance for West Brom as Isaac Price's shot is saved by Daniel Peretz.

Southampton have made a couple of substitutions with Sam Edozie and Cameron Bragg on for Kuryu Matsuki and Flynn Downes.

So far, so good for the Baggies.
