Jake Cooper slots Millwall in front from the first spot-kick, sending Pierce Charles the wrong way in the QPR goal, before Ilias Chair's effort is saved by Lukas Jensen, diving to his right to deny the Hoops.

Mark Sykes, on debut for the Lions after joining from Bristol City, then puts that late own goal out of his mind to place into the corner.

Harvey Vale steps up for QPR's second but Jensen is equal to it once again - diving to his left to make a brilliant save.

We all know goals change games and that's what's happened here.

Everybody was sort of expecting that West Ham approach from the beginning. They have the quality but they haven't shown the attitude until that first goal in the 42nd goal.

Birmingham had one of the poorest away records in the Championship last season, but they lead at the break at Swansea thanks to a late set-piece goal from August Priske.

The goal came against the run of play, with Swansea the better side until they were undone cheaply.

Alex Cochrane's flighted delivery sailed over Cameron Burgess and Josh Tymon, with Priske steering in after Carlos Vicente drilled the ball across the face.

Chris Davies will be delighted to be ahead.

Hopefully a few of the West Ham players have woken up because this is a dress rehearsal. They'll be playing at tempo and teams will respect them, but they won't be giving an inch.

Nuno has to have a bit of a shout and a scream because there are a few players who have not done it.

Football's about winning but to win games you have to put performances in. They won't win many games with performances like that.

Martin Smith
BBC Radio Northampton Summariser

It is tough to see for Northampton, as we are playing a side that we won't be facing in League Two.

The game plan has been to let Leicester have the ball in certain areas, and then the press comes. The discipline which they have been set up with even when they are out of possession - they have done ever so well.

It is 45 minutes of football and it is going to get tougher in terms of the discipline and defensively, because as time goes on and you are chasing the ball you will get tired. So, I think the substitutions will be important.

It has been good so far, and the Northampton players have worked their socks off.

It's all over at Loftus Road and we are heading to penalties.

Luke Cundle tapped Millwall in front after 53 minutes when QPR goalkeeper Pierce Charles spilled a cross on debut.

But Jimmy Dunne forced an equaliser for the Hoops four minutes from time, with his header diverted into his own goal inadvertently by Mark Sykes, who is playing his first game for the Lions.

Not an ideal day for debutants.

Bolton looking the stronger so far at Hillsborough but still nothing to separate the two sides.

Cardiff City, who were trailing League Two Swindon Town early on, have now turned this one around to lead 2-1 via Yousef Salech's quick-fire double - the first of which came from the penalty spot.

Bromley have equalised against Reading thanks to the master poacher Michael Cheek and Wigan have broken the deadlock at Oakwell against Barnsley through Dara Costelloe's tap-in on the line after James Carragher had headed the ball back across goal.

And right on the stroke of half-time, Bradford City have taken the lead against Rochdale through Will Swan.

We're into four added minutes at Loftus Road. We've played two of them.

West Ham comeback from behind to lead 2-1 at the break.

Portsmouth looked comfortable after Adrian Segecic controlled Max Kilman's clearance and found an opener.

But the Hammers finally clicked, working the ball up the pitch well for Mo Kante to set up Valentin Castellanos for a dink in the net.

Captain Jarrod Bowen then took his chance on a loose ball and hit it well with his first touch to put West Ham ahead.

The match has turned on it's head but Portsmouth were well in this for most of that half. Will be interesting to see if that's the case in the second.

An entertaining first half at Pride Park and a late wondergoal from Sam Szmodics has dragged Derby back into the game.

Lincoln were 1-0 up inside three minutes after Ben House nodded home from a corner via a deflection and Dom Jefferies doubled their lead 20 minutes later with a fine finish into the bottom corner, slotting across goal.

All to play for in the second 45.

It was a fast start for Watford who forced an early save out of Crawley’s veteran goalkeeper Vito Mannone.

But the Red Devils hit back with two chances from Charlier Barker and Kellan Gordon before the half-hour mark, to make sure Federico Ravaglia didn’t get too lonely in his net.

The rest of the first half produced very little else except for when Luca Kjerrumgaard had the ball in the back of the net…only for the linesman to raise his flag.

Swansea had all the chances for much of the first half but it's Birmingham who take the lead with a late first half goal from August Priske.

The Swans totted up eight shots at goal in that half, while it took 43 minutes for Birmingham to have their first sight of the net and it ignited a spark that saw Priske net the ball at close range for his goal.

It's the finish that matters and Blues had it. How will Swansea respond?

Andy Rowley
BBC Radio London commentator

It's been a strange first half but suddenly West Ham have surged into life.

Portsmouth are looking a little bit shellshocked.

Dan George

What a strike that is by Jarrod Bowen.

West Ham have completely turned this game around just before the break.

The home fans break out into chants of "you're not singing anymore" towards the travelling Pompey fans.

We will play three minutes of additional time.

Leicester go into the half time break with a lead thanks to Caleb Okoli, who headed in a cross from Luke Thomas.

It seemed like the Foxes would then seek another goal but Northampton came out of their shell and nearly drew level through Connor Lemonheigh-Evans and a Jon Guthrie header.

Overall I don't think the home fans will be too happy with that...but a goal is a goal, and so far they're going through to the second round.
