FT: Stevenage 1-1 Hull
As we wait for the ties that went into extra time to restart, let's take a look at a couple of the goals.
Here's Elliott List's strike that's forced another 30 between Stevenage and Hull.
Carlisle 1-2 Doncaster
League One club Doncaster hang on as Ben Whiteman's first-half double books their passage into the third round.
Barnet 0-1 MK Dons
Cameron Jerome's late winner guides MK Dons into the third round for the first time since 2017-18.
National League Barnet put up a decent fight.
The Dons have never lost against non-league opposition in 11 FA Cup ties.
Shrewsbury 0-0 Oxford City
And National League South Oxford City also force Shrewsbury into extra time.
Both sides are down to ten remember with Aaron Pierre and James Roberts both dismissed for an off the ball incident.
Mansfield 1-1 Dagenham & Redbridge
Could Luke Croll's late miss be costly for Daggers? We'll have to wait and see.
Barnet 0-1 MK Dons
Bees keeper Scott Loach makes a decent save to deny MK winger Daniel Harvie a goal in the second minute of stoppage time.
The hosts need something soon to stay in the Cup.
Stockport 2-2 Yeovil
Ben Hinchliffe's late penalty save keeps Stockport in it. Another 30 await.
A classic cup tie this.
Bristol Rovers 6-0 Darlington
Bristol Rovers showed no mercy as they thrashed National League North outfit Darlington.
The Pirates are through to the third round for the second consecutive season, and Paul Tisdale has his first win since taking charge at the Memorial Stadium.
Stevenage 1-1 Hull
We go to extra time.
Mansfield 1-1 Dagenham & Redbridge
Inches away for Dagenham & Redbridge.
Luke Croll almost wins it for the non-leaguers, as he heads over Sam Deering's free-kick.
Approaching extra time and potentially penalties in four of our ties with just seconds remaining.
Stockport 2-2 Yeovil
So nearly the winner for Stockport!
Jordan Williams flashes in a brilliant delivery across the face of goal, but County striker Connor Jennings can't quite poke it in.
Shrewsbury 0-0 Oxford City
OFF THE LINE!
Shrewsbury finally beat Hoops keeper Ben Dudzinski but defender Aaron Drewe is able to head Marc Pugh's effort of the line.
Mansfield 1-1 Dagenham & Redbridge
Sam Deering is inches away from winning it for Daggers.
He gets in behind the football league side's defence and shaves the far post with an effort across goal.
That was the moment. Not long to go here too.
Stevenage 1-1 Hull
Seven minutes added on in Shropshire. Still anyone's game this.
Stockport 2-2 Yeovil
Terrific stop!
After a long delay Luke Wilkinson steps up and goes to the keeper's right, but Ben Hinchliffe is equal to it. Stockport are still in this one!
Cameron Jerome (82 mins)
Has the old stager put League One MK Dons into the third round?
Cameron Jerome turns home Daniel Harvie's cross which came in from the left from the edge of the six yard box.
That is the 34-year-old's fifth goal since joining the Buckinghamshire side.
Marine 0-0 Havant & Waterlooville
Lowest-ranked club Marine have their first real chance as Niall Cummins has a header saved by Hawks keeper Ross Worner.
Stockport 2-2 Yeovil
This games has it all!
Matthew Warburton is brought down by John Rooney.
Stockport are furious with the decision.
Huge chance to take the lead for the side at the bottom of the National League.
Jon Mellish (78 mins)
The comeback is on!
Carlisle have the goal their second half efforts deserve.
It came from a corner from the left, as Joe Lumley could not hold onto a back-post header.
Jon Mellish was on hand to gobble up the loose ball. League Two Carlisle will be hoping to force extra time now.
