Dan Kemp drives into the Mansfield penalty area and dinks an effort wide from an acute angle.

Then more danger from the Stags as Aden Flint's header across goal is claimed by Robins keeper Murphy Mahoney.

In the balance here.

You have to credit Paul Warne for his tactical changes in this second half.

They've made a real difference.

Also, Sam Finley is desperate to get back on the pitch after spending a few minutes down on the ground.

Much better from Oxford this half, and almost all one-way traffic, but no goal for Des Buckingham's team.

Billy Bodin is the latest to go close with a shot that just fizzes wide of the post.

Stockport are building a little pressure but Newport are so far soaking it up.

Ibou Touray does well to dig out a cross from the left-hand side towards Nick Powell, but his header is too close to the goalkeeper.

So far so good for the hosts. They have half an hour to hold out.

Notts County have one back in the play-off region battle of League Two. Macaulay Langstaff assisted by Dan Crowley who pinched the ball off to make it 2-1 against Wimbledon.

Walsall v Forest Green the only game still goalless in this division.

The referee's got to be strong now, and not try to even it up with a silly red card for Blackpool.

Portsmouth just haven't been good enough.

It is getting close to mission impossible territory now for Portsmouth.

Two goals down and now a man down as Wales international Joe Morrell sees red for a second booking.

Dan Kemp has been good today.

He's been brave enough to take players on.

Swindon need to keep getting him on the ball.

With results elsewhere, Bolton will go top with three points and Jacques Maghoma has put them 3-0 up against Exeter.

Reward for the long trek north for Charlton fans as Corey Blackett-Taylor has opened the scoring away to Carlisle.

Relief for struggling Northampton thanks to Kieron Bowie and Sam Hoskins as they lead Cambridge 2-0.

And a second goal for Shrewsbury at home to Port Vale from Daniel Udoh.

Bradford have the first goal at home to Accrington-Tyler Smith with it.

James Maxwell crosses to Joe Ironside who flicks a header past Harvey Davies to make it Crewe 2-2 Doncaster.

Apter has his second, and Tranmere's third. A shot from just inside the box past Jake Turner with his left peg. Gillingham respond with a double substitution.

Having trailed at the break, the Stags almost turn the game on its head 10 minutes into the second half.

Aaron Lewis has a great opportunity to put them ahead, but his effort is blocked and Louis Reed then loops a volley just over the crossbar.

Ross Heaton

A few nerves are starting to fray.

Portsmouth tempers are at risk of spilling over, here.

Blackpool fans have played a massive part so far.

What have Stockport got in the second half?

The League Two leaders are having the lion's share of possession, but struggled to carve out a real threat to Nick Townsend's goal in the first half.

I'm not sure about that refereeing decision.

For me that looked like it hit a Mansfield arm.

The fans are furious.

Joe Tomlinson brings MK Dons level 2-2 at Salford after great work by skipper Dean Lewington and Alex Gilbey.

Jennings adds a second for Tranmere, this time in front of the Kop. Brad Walker with a lovely cross in for a header past Jake Turner.

Colchester are level with Barrow now as the away side's George Ray, up from the back will contest whether it is his or a Will Greenidge own goal.

No changes yet in this one as Portsmouth try to get that into the game.

This would be a big statement victory for Blackpool if they can hang on - the most significant since Neil Critchley's return to the Lancashire club in the summer.

Josh Murphy is being a cheerleader for the crowd!

Cheltenham haven't got out of their half yet.

Oxford are now playing well...we can't afford another 45 minutes like we've just had.
