Carlisle half-clear a corner but Tom Lowery sees a volleyed effort from the edge of the box bounce back off the post before being scrambled clear.

Carlisle on the attack and Will Norris holds Jordan Gibson's angled drive and then it's Pompey's turn again - Sean Raggett going close with a speculative thunderbolt.

End-to-end stuff.

Harry Isted is not here to make friends at Reading this afternoon, he has denied Sam Smith yet again, getting down to stop his near post effort and once again show why he's back in the line-up under Nathan Jones.

Mark Harris so close to a second for Oxford as he sees a far-post effort cleared off the line after Marcus McGuane had rounded keeper Dan Grimshaw and sent the ball into the middle.

Goals are going in everywhere.

League leaders Stockport have taken an early 3-0 lead over Grimsby. Antoni Sarsevic, Isaac Olaofe and Lewis Cass on the scoresheet.

Doncaster are 1-0 up on Tranmere through a Joe Ironside strike - that's his 15th goal this season.

Accrington have a 1-0 lead over MK Dons thanks to a Jack Nolan goal.

A good start for Morecambe who are trying to keep their play-off hopes alive, they are 1-0 up against Sutton United.

And fellow play-off chasers Newport County have a 2-0 lead over Walsall.

I have to say this is fantasic play from Oxford.

Blackpool don't seem too happy with themselves and that is causing them problems.

The away side look much more composed right now.

Addicks striker Alfie May has his first sniff of goal but a superb recovery tackle from Lewis Wing as he's about to pull the trigger ensures he remains on 16 league goals for the season...

... for now.

The hosts have been putting the leaders under pressure in the last 10 minutes and Luke Armstrong has come close with a far-post scramble to meet a low cross from Josh Vela on the right.

Pompey keeper Will Norris needs a spot of treatment after helping to prevent the hosts taking the lead.

Barrow are just not up for it right now.

The first five minutes they looked bright, but not anymore.

Wimbledon are winning every challenge, and Barrow need a response now.

Harry Isted once again shows his worth in the Charlton goal as he tips away a Sam Smith volley after the Royals had beaten the offside trap with a clever dinked pass from Charlie Savage, with dad Robbie watching on at the Select Car Leasing Stadium..

Cameron Brannagan tries to restore the Tangerines' lead once more but his long-range effort drifts wide.

Playoff-chasing Leyton Orient are 1-0 up against fifth-placed Barnsley through a superb Ruel Sotiriou strike in the 10th minute.

Exeter have a slight advantage over Wigan in a battle between two mid-table teams thanks to their new striker Mohamed Eisa, on loan from MK Dons, it's 1-0 to the home side.

And a terrific start from Port Vale who have taken an early 1-0 lead against Stevenage. Remember, Vale have only earned one point so far in 2024 and a win today could bring them out of the relegation zone.

The home fans are throwing more than just insults at Mark Harris.

When the ball came to him you just backed him to finish it.

It's so important Oxford levelled quickly.

Joe Rafferty wins possession in midfield and finds Paddy Lane down the right channel but the Pompey man sees an angled drive stopped by Carlisle keeper Harry Lewis.

I think the way Mansfield keep the ball and counter suits them really well while playing away.

They look settled, patient, and are moving the ball around nicely.

Although, I think the Stags need to use the wider spaces better.

Harry Isted was recalled between the sticks in Nathan Jones' first Addicks line-up today and he's just repaid his new boss with a flying save to deny a fierce Lewis Wing drive which looked destined for the top corner.
