Gateshead started their cup run back in September, winning 6-0 against Ramsbottom.

The Tynesiders are currently ninth in the National League North, level on points with Brackley Town who occupy the last available play-off spot.

They face an Oldham side who are coming off the back of two defeats in their last two league games.

It means the Latics sit 20th in League Two, three points off the relegation zone.

Nothing comes of the set-piece.

I know it's a cliche but honestly I'm struggling to work out which team is in the National League and which is in League One.

Having said that, League One Southend have just gone on the break and Isaac Hutchinson has forced a save out of Dover keeper Yusuf Mersin.

National League side Barnet entered this year’s competition at the fourth qualifying stage had made heavy weather against local rivals Potters Bar who took them to a replay.

In the league, they sit 10th, coming off the back of a 2-1 win over Chorley.

Joey Barton's Fleetwood Town are looking to reach the third round of the FA Cup for the third year running.

Town are fifth in League One but lost 2-1 to Bolton in their last match.

And now Stephen McLaughlin gets a yellow for a very late challenge on Dover's Michael Woods.

Free-kick in a good area coming up for the hosts.

Maldon & Tiptree may have never reached this stage of the competition before but they come into this one on sparkling form.

They sit second in the Isthmian North table winning all eight of their league games.

In fact, the Jammers have won 19 of their total 20 games this season.

They travel to an Orient side who are 16th in League Two.

Big chance for Southend's Stephen McLaughlin. The forward receives the ball in the area on the bounce.

But he can't get over it and toe pokes it over the bar.

Let off for Dover.

Southend's Elvis Bwomono goes into referee David Rock's book after a meaty challenge on a counter-attacking Inih Effiong.

Chippenham Town are relative strangers when it comes to reaching the FA Cup first round.

The National League South club host League Two Northampton Town in just their third appearance at this stage in nearly 150 years.

Manager Mark Collier has left "no stone unturned" in preparing his side while striker David Pratt will hope to "tap-in" to his day-job skills as a plumber by exposing what he hopes is a "leaky" Northampton defence.

Not much to update you on so far.

Southend had a succession of corners a few moments ago, while Dover have had two tantalising crosses into the box just out of reach of attackers.

This tie pits two out of form sides against each other.

Wrexham, who have struggled in the National League this season, take on League One strugglers Rochdale.

Last season Wrexham faced off against Welsh rivals Newport County in round two, while who could forget Rochdale's own cup run this season in the EFL Cup as they almost bested Manchester United at Old Trafford.

What these sides would give for another run this season.

Macclesfield Town's FA Cup first-round tie against Kingstonian will go ahead today despite the Silkmen's players going on strike over unpaid salaries.

BBC Radio Manchester understands wages for October are still to be paid to players and staff.

Their team today includes five loanees and six youth team players.

Macclesfield's place in the competition for both this season and 2020-21 would be at stake if the game was called off.

Both sides are looking to size each other up. Southend - in their all yellow away strip - have been in Dover's box a couple of times but nothing has come from it.

Hamish Stewart: Please keep an extra eye on Macclesfield v the mighty Kingstonian. Stuck at home nursing an open fracture to my ankle instead of being there cheering on the Ks.

Rest up Hamish! We'll bring you all the action from Moss Rose as it happens.

And here we go, three hours of Sunday FA Cup football start now.

We'll have a minute's silence for Remembrance Sunday, ahead of all of our fixtures today.

The players are out, the stands are packed to the rafters, one fan has drum he hasn't stopped banging for the last 20 minutes; this is what the FA Cup is all about.

I make it three minutes until kick-off.

Mozziephotography: Roped in a few times to referee Sunday League matches. No qualification apart from school football games. Talk about trying to pull the wool over your eyes.

Sauce that rocks: in year 12 I was running the line for the year 12 v year 13 Classico. Took months of abuse from my classmates after not giving an offside decision against the winner for year 13.

After both the referee and fourth official went down injured in the tie between Accrington and Crewe yesterday we're after your memories of having to fill in as a match official.

Or, any games you've been at which have seen someone called out from the stands to fill in as a fourth official.

We'll be across updates for the 12:00 GMT Kick-Off between Dover and Southend, with Sol Campbell still looking for a first win as Southend boss.

Dover currently sit mid-table in the National League and recent results echo their position as they’ve won two, drawn two and lost two of their last six matches.

But, Southend are on a four-match losing run which has included a 7-1 defeat to Doncaster.

A potential upset?

In yesterday's tie between Accrington and Crewe, both the referee and fourth official went off injured and, after a lengthy delay, the two managers were forced to decide which end the linesman would run the line by a coin toss.

An extremely unusual situation, I'm sure you will agree, but we want to know your experiences of daft refereeing situations.

Ever had to rope a mate in to officiate in a Sunday league game? Have you yourself been plucked out of the crowd at a match you're watching to run the rule?
