Bradford left it late as they came from two goals down to eventually beat Burton Albion in extra time and claim a place in the next round of the League Cup.
The visitors had looked to be cruising through as a Billy Kee strike from an Anthony O'Connor ball saw them take the lead and Aaron Webster headed home from a Jack Dyer pass to double Burton’s advantage.
However, with seven minutes left Nahki Wells managed to grab one back after an assist from James Meredith and Wells sent the game into extra time, latching onto a pass from James Hanson.
Just five minutes before penalty kicks Stephen Darby got the winner as he thundered a long range effort in.
Swansea survived a huge scare to overcome League One side Crawley Town 3-2 in the dying minutes of an entertaining game.
Garry Monk's last-gasp strike spared the blushes of Michael Laudrup's men after goals from Josh Simpson and Hope Akpan had given their lowly opponents a shock lead.
Michu had earlier opened the scoring for the Swans, but Crawley looked to be on the verge of a famous scalp until Danny Graham's effort 15 minutes from time set up a late comeback.
Ten man Sunderland edged out a competitive MK Dons as Craig Gardner and James McClean helped Martin O’Neill’s side ito victory.
With just over half an hour gone Mackems skipper Lee Cattermole was sent off after a challenge on Adam Chicksen.
But the visitors bounced back to take the lead when Gardner hit a free-kick from just outside the box, after McClean was brought down by Anthony Kay.
McClean then doubled the lead for the Black Cats as he received the ball from Jack Colback and rattled the ball into the bottom corner of the net.
Middlesbrough secured an easy victory away to Preston North End, with Emmanuel Ledesma, Merouane Zemmama and Richard Smallwood getting the goals.
Ledesma opened the scoring early on as he smashed home a strike from just outside the box, past Steve Simonsen in the home goal.
The visitors doubled their advantage just five minutes later as Smallwood played the ball to Zemmama and the former Hibernian midfielder made no mistake in firing home.
Five minutes before the half-time whistle Preston got one back as Jack King got on the scoresheet for the home side.
But, just after the hour mark, Middlesbrough killed the game off as Smallwood found the bottom left-hand corner of the net to see his side through.

Saints secured the tie with just over ten minutes remaining in the game, as Joe Mattock brought Steve De Ridder down and Rodriguez stepped up for his second goal of the night.
Swindon claimed victory over Championship outfit Burnley as Paul Benson, Andy Williams and Troy Archibald-Henville all found the net.
The home side took the lead as former Scotland international Jay McEveley found Benson, who made no mistake with his strike from close range.
Williams doubled the lead for Paolo Di Canio’s side just before the half time break as he received the ball from Tommy Miller and slotted it beyond veteran keeper Brian Jensen.
Former Swindon striker Charlie Austin had looked to have got Burnley back into the game as he rounded Wes Foderingham after being put through by substitute Sam Voakes.
But that wasn’t to be enough as Archibald-Henville got his head to a cross from McEveley to secure Swindon’s place in the next round.
