Southport boss Gary Brabin, speaking from the Pride Park dug-out: "We've got on slightly better terms in chances and gave them a scare there. We've got the legs and the energy and the enthusiasm to keep going. But we're up against a good side. We're not just defending but causing problems on the attack."

Graeme Swann looks cheesed off in the stands. Does anyone still believe in Blyth? One more goal would do it. They look absolutely shot right now though.

Brilliant defending from Swansea as a number of players make last-ditch interceptions to deny Tranmere at a goal-mouth scramble. They are giving the hosts nothing.

The first win of the post-Pardew era is still proving elusive for Newcastle.

The Magpies still trail and don't show much sign of picking their way through the Leicester defence.

A little under 30 minutes to go.

Matt Murphy: What a turnaround. Regardless of everyone wanting underdogs Blyth here, Birmingham done well to score 3 in 15 mins

Carl Stewart: Dejected isn't the word at the minute @Blyth_Spartans

Amy-Elizabeth: Birmingham clearly didn't get the memo #BlythSpartans

Chances at either end! A rare sight of the Derby goal sees Southport striker Richard Brodie's header stopped, before the Rams desperately clear their lines after a game of pinball inside the home penalty area.

Then, Southport's Spanish keeper David Raya Martin produced three excellent saves in quick succession as Derby hit back.

Doncaster take a deserved lead against the League One leaders. Harry Forrester's corner is hooked in by Luke McCullough from close range.

They were 1-0 down, but Bournemouth are now in front as Junior Stanislas has put them ahead at fellow Championship team Rotherham. Stanislas latched on to a pass from Dan Gosling before he rounded Adam Collin in the Millers' goal and calmly finished.

Stuart Pearce's half-time words appear to have taken effect as Lars Veldwijk heads wide from six yards out and Britt Assombalonga also goes close. Forest clawing their way back into this tie.

Reporter Peter Slater at Hawthorns: "It's a bit unfair this scoreline on Gateshead. They don't deserve this."

"Give Birmingham credit. They've come out for a dogfight in this second half and are utilising the advantage of the breeze. Blyth have been unable to maintain their tempo and the question now seems to be just how many Birmingham will score, because Blyth simply can't get onto the ball and the back four are dropping deeper and deeper, looking really very leggy."

Rotherham United goalkeeper Adam Collin produces a fine save to tip Adam Smith's powerful effort over the crossbar. Still 1-1.

And just like that, the dream could be over. Birmingham playing the part of party poopers to perfection with three quick, ruthless goals. Wes Thomas grabs his second of the game with a free header from a half-cleared corner. You could hear a pin drop inside Croft Park all of a sudden.

New half, same pattern of play. Derby fizz the ball around quickly like the Premier League-chasing side they are, the yellow shirts of non-league Southport tearing around desperately to stop them.

Rams defender Lee Naylor fires over, then Jake Buxton's header is deflected out for a home corner. Southport still hang on.

Mo Barrow has been impressive for Swansea this afternoon, and the 22-year-old forward taps into an empty net on his full debut after being teed up by Bafetimbi Gomis. Game over?

There's little sign of Tranmere having the ability to turn this one around as Shamir Fenelon tries a speculative effort from 40 yards out which is straight at the keeper.

"Birmingham have finally started playing the conditions, and that goal came from a ball over the top. It was a good finish by Wes Thomas and Birmingham are now dominating this game. Blyth manager Tom Wade now must make a couple of changes because his team are looking tired."

This is getting ugly.

0-0 until 42 minutes, Gateshead have now shipped five in 13 minutes either side half-time.

Substitute Georgios Samaras slips in Chris Brunt who rounds Adam Bartlett to slot home.

Probably fortunate that he did because a despairing and late defender's challenge would have resulted in a red card had he missed.

Great comeback from Birmingham, Gary Rowett must have really got into his players at the break. The Blues have gone direct and score a cracking second goal, Wes Thomas chasing a long ball over the top, getting his head down and lacing a left-footed drive into the net. Upset over?
