Right, we'll stick our necks out here - Blyth are surely into the second round after Danny McGuire bravely pokes the ball under the Altrincham keeper as the pair collide to make it 4-1.

What a great result that will be for Blyth, against an Altrincham side who play two sides above them in the Conference.

Reda Johnson, the big former Sheffield Wednesday defender, has now gone up top for Coventry. The Sky Blues have just seven minutes to grab themselves an equaliser - although Worcester goalkeeper Nathan Vaughan is doing his level best to waste as many of those as possible, and receives a yellow card for taking too much time over a free-kick.

It's a needless second yellow, immediately after Pompey had levelled. Defender Paul Robinson, booked for a heavy challenge earlier in the second half, slides in unnecessary and it's a fair decision.

Momentum lost.

Pompey are still in the cup. It's a good ball in, flicked on and captain Danny Hollands heads in from inside the six yard box. Relief for the League Two side. Now, who wants this more?

Blyth Spartans might be there now with time running out, Robbie Dale foxes the keeper to slot home for his second making it 3-1 against Altrincham.

Notts County and Accrington Stanley fans, we're not ignoring you - it's 0-0 in the 15:00 kick off.

The 10 men of Coventry City have a way back into the tie. Captain Reda Johnson, who missed from the spot in the first half, pokes the ball in at the far post to halve the deficit. Game well and truly on.

So we're into the last quarter of an hour in each of our nine 14:00 GMT kick-offs. The big story of the afternoon so far has been at the Ricoh Arena, where Conference North side Worcester City lead the 10-men of Coventry City 2-0.

We may also have a shock on our hands at Fratton Park, where non-leaguers Aldershot are 2-1 up on 2008 FA Cup winners Portsmouth.

Can they see it through? Don't go away!

Jordan Roberts curls in a free-kick which bounces awkwardly just in front of Paul Jones, who does well to turn it wide. Rather than sitting on their lead, the non-league side are pushing for a third.

Chesterfield are easing into the second round, and Braintree are giving them a hand, with an own goal from Clerima making it 5-0 to the rampant Spireites.

Freddie Sears, an ex-Premier League striker, seems to have snuffed out the comeback at Gosport Borough, who now trail Colchester 5-2 after the former West Ham man grabbed his second.

How will the League Two side respond? They have hardly had a shot since the break.

Portsmouth haven't won an FA Cup tie since beating Tottenham 2-0 in the 2010 semi-final at Wembley.

Since then they've lost twice to Chelsea, including in that year's final, and also crashed out to Brighton, Notts County and, most recently, Stevenage. It's not been an easy four-and-a-half years for Pompey, has it?

But defeat here would arguably trump all of those defeats.

Sean Geddes, your race has been run, and what a race it's been. The two-goal Worcester City hero is replaced by Connor Gater with around 15 minutes to go.

A superb finish from Kyle Perry, who lobs the keeper from 20 yards from a downfield punt, pulls a goal back for Altrincham at Blyth Spartans, where the score is now 2-1 for the north-east club. Blyth, don't forget, play two leagues below their Conference opponents.

Rob Ramshaw has his hat-trick, his header makes it 4-0 for Gateshead away at Norton United.

Coventry win a free-kick around 30 yards from goal, but James Maddison's powerful-looking strike can't get any further than the wall. The Sky Blues recycle possession though and chuck it in towards the penalty area, but the ball drifts harmlessly out for a goal kick. We're marching into the final 20 minutes here.

The Conference side lead and it is no less than they deserve. It's been all Aldershot. Mark Molesley gets in front of his man at the near post and tucks the ball home to send the away fans wild. The 2008 winners are in trouble here.

Dame Fortune (aka Lady Luck) smiles on Gary McSheffrey as he bags his second deflected goal of the day, to give Scunthorpe a 2-0 lead at Forest Green.

Worcester come within inches of making it 3-0 and maybe, just maybe, putting this remarkable tie to bed once and for all. Substitute Nick Wright smashes a shot towards goal from inside the area but it's deflected just wide, with goalkeeper Ryan Allsop stranded.

Pompey are living dangerously.

The ball falls to Aldershot's Brett Williams in the box from a corner but he drills it wide across goal. There were so many bodies in there, that could have gone anywhere.

The Shots fans' arms go up. They want a penalty after a clumsy challenge from Joe Devera. Nothing in it.

The visitors have enjoyed a small spell of pressure though, without really troubling Pompey keeper Paul Jones.

The Sky Blues almost have a goal back - but if they had done, it would've been controversial to say the least. As the ball comes in from the left, Worcester goalkeeper Nathan Vaughan clatters into his team-mate Wayne Thomas and stays down. But the League One hosts decide to play on, and Jim O'Brien twice strikes the ball towards goal yet can't squeeze in it. Close.

BBC Hereford & Worcester commentator Dan Johnson says the Worcester City fans are in "dreamland". He's not far wrong either - they'll realise their side are little more than half an hour away from one of the upsets of the weekend.
