Crewe make two more changes. On come Kyle Ure and Adrien Thibaut, for Reece Hutchinson and Josh March.

Chesterfield also make two subs with Lewis Gordan and Lee Bonis on for goalscorer Fraser Bryden and Tom Pearce.

It's been quite frantic and a bit chaotic in places but this has been a decent game of football.

The game is on a knife edge and could go either way. Yes, Bradford are having lots of the play and asking all the questions but don't rule Oxford out yet.

Doncaster boss Grant McCann can see the danger and brings on fresh legs - eight of them.

On come Brandon Hanlan, Alfie May, Tommi O'Reilly and George Broadbent.

Will Keane, Isaac Hutchinson, Hakeeb Adelakun and Jamie Sterry are off.

Burton Albion have leveled up against Leyton Orient following Kgaogelo Chauke's goal on the hour mark.

Reading have also equalised against Barnsley after Kyreece Lisbie's goal and Mansfield now lead Blackpool 3-1. Rhys Oates re-gained Mansfield's advantage and Blackpool's Ilmari Niskanen has just put through his own net for an own goal.

Wycombe have equalised at AFC Wimbledon through Fred Onyedinma's goal.

Notts County still lead Stockport 1-0.

So close for Bradford.

Ibou Touray launches a long throw into the Oxford box which the home side fail to deal with and Kayden Jackson pokes the ball inches wide of the post.

One of those days?

Away from the dismantling of Crewe, League Two is full of goals.

Tyler Walton has got a second goal for Accrington, who lead Rochdale 4-0.

Grimsby have shot ahead 3-1 against Gillingham thanks to a penalty from Iwan Morgan, and a goal from Geza Turi.

Exeter took the lead against Fleetwood through Charlie Cummins, before Ronan Coughlan made it 1-1 three minutes later.

They say the goalkeeper is the most important position on the pitch.

Well Doncaster stopper Tommy Simkin has made three outstanding saves in this second half to keep the score at 2-0.

Wednesday continuing to test Rovers here.

There are just signs Sheffield Wednesday are going to take those risks we mentioned.

Ali Al Hamadi is kept out at close range by Tommy Simkin who then pushes away a Mason Burstow shot.

Oxford roll the dice with three changes.

Tyler Goodrham, Mo Missanga and Jack Currie get the hook.

Mark Harris, Peter Kioso and Aidomo Emakhu are on to see if they can unlock this game.

Surely there won't be another 5-5 epic today...

Chances at both ends.

First Isaac Hutchinson's shot is straight at Ashley Maynard-Brewer before Barry Bannan is superbly denied by Tommy Simkin.

Wednesday are going to have to start taking a few risks.

Will Keane whips a shot wide for Doncaster - it is actually pretty close.

Keane is making his first start for Rovers today and has had a couple of decent chances to mark it with a goal.

There is still time.

Summariser on BBC Radio Cambridgeshire

Cambridge United have themselves a goal back. We said they needed something and they needed it quickly, and they've got it through Sullay Kaikai.

He's given United a lifeline with a neat finish in the end. Simple but it did the job.

Are we witnessing another comeback from United?

Tom Gayle
Final Score at SMH Group Stadium

A chunk of the away support quickly left after the fourth goal went in.

Two tap-ins, a header, an own goal, plus Mandeville's long range cross come shot, courtesy of a huge assist from the windy conditions (I'm sure he'll say he meant it).

All of this against a side who only lost for the first time this season on Tuesday against Exeter. Plus, prior to this afternoon had the meanest away defence in the division.

Bradford boss Michael Duff is the first to go to his bench.

Nick Powell replaces Will Swan up front.

An opening for Sheffield Wednesday and for skipper Barry Bannan.

His shot hits the target but Tommy Simkin makes a good save.

Chesterfield go for a sixth as Liam Mandeville takes a left footed shot from outside of the box. It curls, and goes well wide of the goal.

Two huge saves from Oxford's Jamie Cumming.

First he keeps out Callum Connolly's shot and is quickly back up to deny George Lapslie.

Is this one finally opening up?
