Chris Porter (35 mins)
Blackburn down to 10 men! Rovers defender Rekeem Harper is sent off for bringing down Chris Porter as the last man, and Porter picks himself to stroke home the penalty.
Game on again?

Final Score
Woking boss Anthony Limbrick:
"It was disappointing to concede as it was the first time Peterborough had entered the penalty area and got a chance.

"We've been really positive with the start we've had. They thought we'd drop off but we've gone for them."

You won't see many better free-kicks than this!
Sam Saunders curls one in from at least 30 yards, and League Two Wycombe are back level against seventh-tier Leatherhead.
Our Final Score pundits say the goalkeeper may have done a little better with it, but it's still a super strike from Saunders.
Duckens Nazon (27 mins)
Disappointment for National League side Boreham Wood, who are behind at Coventry.
Duckens Nazon picks up the pieces to fire home a rebound for the Sky Blues.
We're fairly sure he'll be the only Haiti international scoring in the FA Cup this weekend.
The big news so far is seventh-tier Leatherhead, the lowest-ranked team left in the FA Cup, leading away at League Two club Wycombe.
What a story it will be if they can make it into Monday's third-round draw!
Ryan Tafazolli
Meanwhile at the Laithwaite Stadium, Peterborough United have taken the lead against Woking.
After a free-kick flies into the Woking box, it's spilled by host keeper Nathan Baxter and Ryan Tafazolli flicks into the net from close range.
Karlan Ahearne-Grant (22 mins)
Karlan Ahearne-Grant equalises for the visitors, converting Mark Marshall's cross from six yards.
Blackburn 3-0 Crewe
Danny Webber
Former Watford and Sheff Utd striker on Final Score
Blackburn have been absolutely brilliant. Every time they get the ball, they look threatening. They've shown class with the goals they've scored, but Crewe have got to defend better as well.
Dominic Samuel (20 mins)
Dominic Samuel has now scored two and made one for Blackburn, who are cruising into round three.
Rovers broke quickly and it's a neat finish from Samuel when through one-on-one.
Tommy Rowe (16 mins)
Rovers are in front and it is a howler from Scunthorpe's Matt Gilks.
There looks to be no danger as the Iron's Duane Holmes passes the ball back to goalkeeper Gilks, but he dithers in possession before hitting the ball against the advancing Tommy Rowe, who controls it before slotting home.
I don't think Gilks will want to see that one again later.
Gateshead 0-0 Luton
The League Two leaders are seeing plenty of possession at the Gateshead International Stadium.
Image source, OptaWoking 0-0 Peterborough (14 mins)
Woking win an indirect free-kick in the Peterborough box after a backpass and it's laid on to Joey Jones on the edge of the area, but he lets fly high and wide of the mark.
Will the National League side be kicking themselves come the end of the game after missing that chance?
Danny Graham (15 mins)
Blackburn double their lead very quickly - Danny Graham gets on the end of a pass from Dominic Samuel and slides a shot into the corner across the goalkeeper.
Dominic Samuel (10 mins)
Could the goalkeeper have done more here?
Dominic Samuel latches onto a pass inside the area and beats a defender with some fancy footwork before firing towards goal to make it 1-0 to the League One side.
Cody McDonald (10 mins)
A close-range finish from Cody McDonald puts AFC Wimbledon ahead against their League One opponents.
Wycombe 0-1 Leatherhead
Kevin Kilbane
Former Everton winger on Final Score
There's not a lot in it and I think the referee's booked the wrong player. It's physical and you're expecting a defender's going to get an arm across you.
