Seeing that Tweet makes me glad I work in a lovely, warm office.

I don't like heights, I'm not a fan of the cold and I panic in front of a microphone.

Keep warm Mark! :)

This game has really come to life now since that goal.

Gillingham look a team reborn and they press towards Sunderland's goal once again. They win a corner but can't make the most of it.

Right then, we're back under way at the Stadium of Light.

Big 45 minutes up ahead, we'll keep across that game as we finish off the last of the 15:00 GMT previews.

Shrewsbury have had a memorable couple of seasons in the FA Cup, reaching the third round two seasons ago when they welcomed the BBC cameras to New Meadow as they faced West Ham.

Then last season they held Premier League side Wolves to a replay in the fourth round.

League Two form side Bradford stand in their way of another run this season.

Today sees two sides with some of those on either side knowing what it's like to come close to oblivion.

Bolton, who narrowly avoided liquidation earlier this season, welcome Ryan Lowe's Plymouth.

Lowe previously managed Bury, prior to them being expelled from the English Football League, before joining the Pilgrims this summer.

Plymouth come into the game off the back of a 4-0 hammering by local rivals Exeter. Today represents an opportunity for them to get back on track against a Bolton side who've suddenly found some form at the foot of the League One table.

Just five years ago there were three tiers between these two sides but things move pretty fast in football.

Today Ebbsfleet United take on fellow National League side Notts County for the chance to reach the second round for the first time since changing their name from Gravesend & Northfleet.

Ebbsfleet have struggled this season and are in 22nd place in the National League having appointed caretaker Kevin Watson on a permanent deal earlier this month.

However, they are unbeaten in three and have picked up seven from a possible nine points heading into today.

Believe it or not, Mansfield are facing some FA Cup first round veterans today.

Maybe veteran is too strong a word, but National League side Chorley have reached this stage of the competition three seasons in a row.

Fleetwood and Doncaster have stood in the Lancashire side's way of reaching the second round in the past two seasons, but can they overturn that today?

Right, in you come lads. Get yourself a well-earned energy gel.

Aiden McGeady's strike is all that separates these two sides at the break as Sunderland lead Gillingham.

Both teams in this tie are looking to reach the FA Cup second round for the first time in their history

To be fair, Nantwich fans have been waiting slightly longer to see their side play in the second round, with the Dabbers having been formed in 1885, a full 133 years before their opponents today.

Despite their very limited history in the competition, the National League side will be favourites for this one at the Northern Premier Division outfit.

As we close in on half-time in today's early kick-off, are Sunderland fully in control of the tie after Aiden McGeady's opener or are Gillingham pushing for an equaliser?

Well so far the answer is neither, but it's an open game at the Stadium of Light and an entertaining affair for the neutral.

The Gills come into this game having beaten Premier League side Cardiff City last season, but they have failed to progress in five of their past six FA Cup ties against league opponents.

We might be losing another tie soon....

It's no secret that the FA Cup can radically change the fortunes of some non-league sides.

Paulton Rovers president Les Rogers told BBC Points West earlier this week how the windfall from their 2009 FA Cup first-round tie is still helping, exactly 10 years on from facing Norwich City on 7 November 2009.

The Bristol-based amateurs crammed 2,070 fans into their ground and the match was selected for live television coverage, seeing them earn more than £100,000.

Today is a big day in the recent history of Carshalton Athletic as they prepare to make their first appearance in the FA Cup first round for over 20 years.

The last time the Isthmian League Premier Division club reached this stage of the competition, Tony Blair was Prime Minister, Google hadn't even been founded yet and current Premier League champions Manchester City were battling relegation to the third tier.

Today they face National League North side Boston United having sealed their tie thanks to sweeping aside Dagenham & Redbridge in the fourth qualifying round.

Can they reach the second round for only the second time in their history?

What have Gillingham got in response to Sunderland's opener?

Well they almost equalised in quick time! Olly Lee put a ball into the box which put Sunderland Jon McLaughlin under some pressure before he punched it into safety.

It's the news we feared when a pitch inspection was arranged.

Yeovil's tie against Hartlepool is off after heavy rain in Somerset left the Huish Park pitch waterlogged.

There's no date for a re-arranged game yet but it's likely to be the week after next when any first round replays will be staged.

It's very much a case of familiar territory for Oxford City this afternoon as they make an appearance in the first round proper for the third season in a row.

A memorable 1-0 away win against Colchester United in 2017-18 saw them advance to the second round where they were defeated by Notts County.

Meanwhile, last season they took then-League Two side Tranmere Rovers to a first round replay before their 2-0 loss at home.

This season, for once, English Football League opposition don't stand in their way as they welcome Solihull Moors to Marsh Lane, with the National League side riding high and hoping for a big tie of their own after they sealed a second round place last season.

Of all today's ties between teams from different levels of the pyramid, few have 'potential shock' written all over them quite like this one.

Struggling EFL team? ✓

In-form non-league side recovering after difficult period? ✓

Non-league side managed by a former player who once scored a winning goal against Inter Milan? ✓

Walsall boss Darrell Clarke will know that defeat today by National League North Darlington could mean the end for his very brief spell with the Saddlers.

The Quakers, managed by former Middlesbrough and Ipswich striker Alun Armstrong, have taken 10 points from their past four league games - which is 10 more than Walsall have taken from the same number of games.
