It's early in the second half at Aggborough and, as it stands, National League North side Kidderminster Harriers are on course to cause another second-round upset as they lead FC Halifax Town, of the National League, 2-0.

Amari Morgan-Smith slotted Kidderminster into a second-minute lead, with former Wolves youngster Ashley Hemmings firing home the second.

Harriers are looking to reach the third round for the first time since 2014 when they were knocked out by Sunderland in round four.

We've already had a couple of results today, which we'll tell you more about at half-time in this game, plus there's also another tie currently in its second half...

Still got room for more FA Cup action?

Good. We're up in Greater Manchester for the last tie of the day, the city of Salford no less.

It's League Two Salford City against National League leaders Chersterfield.

The floodlights are on and the crowds are flocking in to the Peninsular Stadium.

The prize up for grabs - a precious place in the third round.

So that's two wins for League One sides so far, with both high-flying Plymouth and Wigan winning on the road to reach round three.

That's it, it's all over and Wigan are into the third round.

Callum Lang's brace proves enough to knock out their plucky League Two opponents Colchester.

Colchester keeper Jake Turner wins the header from that corner but cannot direct it on target. Wigan breath again. One minute of stoppage time left.

Late, late corner for Colchester. It's now or never for the U's.

Arguably the biggest upset of Saturday came at Fratton Park where Jack Diamond scored a dramatic late winner as League Two Harrogate knocked two-time winners Portsmouth out of the FA Cup.

The North Yorkshire side will play in the third round for the first time in their history.

Is that Colchester's chance gone? Freddie Sears lays the ball off to substitute Chay Cooper but he cannot keep his effort down.

Into four minutes of stoppage time.

Almost a third for Wigan. Some patient build-up play leads to Jordan Jones whipping in a fine cross which both Will Keane and Callum Lang cannot quite latch on to.

Port Vale were one of four League Two sides to upset League One opposition and reach the third round of the FA Cup on Saturday.

And they did it the hard way, but coming back to beat fellow Staffordshire side Burton Albion courtesy of Dennis Politic's second-half brace.

Into the last 10 minutes at Colchester with Wigan with their noses in front thanks to Callum Lang's brace.

Can the U's force an equaliser?

All over at the Crown Oil Arena and League One Plymouth have a place in the third round.

Luke Jephcott's late finish proved enough to win it for Argyle and end a run of three successive league defeats for Ryan Lowe's side.

Jake Beesley can't believe he hasn't scored!

The Rochdale striker does everything right, powerfully heading George Broadbent's cross downwards from six yards. But Michael Cooper has other ideas and brilliantly saves with his feet.

That could be a match-winning save.

Into five minutes of stoppage time. What do Rochdale have left?

Hartlepool United have had an odd few weeks after promotion-winning boss Dave Challinor opted to leave to join Stockport County.

But new boss Graeme Lee could hardly have got off to a better start than by winning at League One side Lincoln City to book a place in round three.
