What a turnaround! And what a strike it is too from the man who looked to be Bradford's most dangerous player before half-time. Another early pass into the penalty area finds Filipe Morais, and his thumping strike across goal gives Matt Glennon no chance whatsoever. In the space of seven second-half minutes, the Bantams have turned this tie on its head.

And, right on cue, Jon Stead has levelled things up. Billy Clarke is unsurprisingly involved, turning a lovely little pass around the corner into Stead's path, and he rounds the keeper before slotting home. Bradford had to seek permission from Stead's parent club Huddersfield for him to play in the FA Cup today - and boy, will they be glad the Terriers said yes.

Billy Clarke is wasting no time in making an impression for the visitors, finding space in the penalty area but seeing his near-post effort turned away by Matt Glennon in the Halifax goal. All Bradford at the start of this second period.

It's a really strong start to the second half by the Football League side, throwing in a couple of early crosses, but the home team are staying strong for now. Is this early pressure a sign of things to come?

So what are Bradford City really made of? We're about to find out, as the Bantams get us under way in this second half. Their manager Phil Parkinson has decided to make one change, as Billy Clarke is on for Andy Halliday.

If it's a Sunday afternoon Cup upset that you're after, then the little town of Nailsworth in Gloucestershire may be the place for you.

Forest Green Rovers, a non-league side with an ex-Football League strikeforce in the shape of Lee Hughes and Jon Parkin, host third-tier strugglers Scunthorpe at The New Lawn.

The Iron, promoted from League Two last season, have already opted to part with record-breaking manager Russ Wilcox and, under new gaffer Mark Robins, their focus may well be on escaping the relegation places rather than FA Cup progress.

For Conference North Worcester City, this is their first appearance in the first round of the Cup in nine years - and manager Carl Heeley has described the build-up to today's clash as "mayhem", with more than 2,000 away tickets sold.

These two teams met in the third round in January 1983, when the Sky Blues won 3-1 at Highfield Road after the non-leaguers had taken the lead.

Worcester's players may take inspiration from the club's most famous Cup giant-killing, back in 1959 when they knocked out Liverpool, then of the Second Division, 1-0.

If you want goals, then the Autonet Stadium could well be the place to provide them this afternoon.

Eighth-tier Norton United, making their first-ever appearance at this stage of the FA Cup, have already scored an incredible 19 goals in this year's competition - that's three more than Arsenal managed in their entire Cup-winning run last season.

A week on from beating Brigg Town 7-4, Scott Dundas "attack-minded" team face a Gateshead side who are third in the Conference.

One great manager who never had the privilege of lifting the FA Cup was former Derby and Nottingham Forest boss Nigel Clough.

However, Gosport Borough of the Conference South will be hoping for a little magic from the two-time European Cup winner today against League One side Colchester United.

Every year Gosport boss Alex Pike visits Clough's statue in Nottingham each year and makes a wish.

"The last four seasons it's come true," Pike told BBC South Today. "This year I asked him to get us to the third round proper."

While the two managers go to work on their players during half-time at The Shay, we can take a quick look forward to a few of our 14:00 GMT kick-offs.

We'll be keeping a particularly close eye on 2008 winners and 2010 finalists Portsmouth, who welcome Hampshire neighbours Aldershot to Fratton Park.

Shots striker Brett Williams, who has scored seven goals for the Conference side so far this season, admitted to BBC Surrey: "I screamed my head off when the draw came out."

You'll need to show a bit more composure than that in front of goal today, Brett.

Wayne Jacobs, former Bradford and Halifax defender:

"For all Bradford's possession, chance-wise Halifax have dominated. They have looked ever so good at set-plays, and if they can do the ugly side of the game and stop Bradford, more chances may come their way."

And that will be that for the first half. Lois Maynard's early poacher's finish has Conference side Halifax ahead against Bradford of League One at the break. Neil Aspin's men haven't seen too much of the ball but, on chances, probably do deserve to be ahead.

Ilyas Najib:, external What an effort by Halifax, we look like the league team, Bradford City look like a Sunday league team.

Steve Williams is going into the book for a poor challenge on the right-hand side. Billy Knott's free-kick is easily dealt with again though, and we're into one minute added on.

Bradford are back on the ball and are probing, searching for a gap. This is patient stuff from the away side, but as a ball is finally launched into the area, Jon Stead's volley on the turn is nowhere near troubling the Halifax goal. He was well marshalled by Shaymen defender Marc Roberts, in fairness.

What a chance that is for FC Halifax. They are are doing most of the defending but, at the same time, are still creating the better chances. Striker Scott Boden peals off his man to latch onto a low cross into the area, but his side-footed attempt goes over. So close to 2-0.

I do wonder how much the Bantams are missing their big man up top James Hanson here. Jon Stead is working tirelessly, but just doesn't quite carry the same physical presence as Hanson, who rose to prominence with his role in Bradford's 2013 League Cup run.

Stick with us Paul, we'll keep you updated as two non-league sides with fine FA Cup pedigrees go head-to-head later this afternoon...

What a save that is from Bradford goalkeeper Ben Williams, magnificent. It's his error, failing to deal with a long ball into his penalty area, that gives Halifax the opportunity to swing in another corner. Again the defending could be better, but the far-post header from Steve Williams is superbly turned away. There's some serious set-piece woe for the League One side here.
