Winners go into second-round draw on Monday
Ben Chrisene (43 mins)
Norwich look to be safely into the second-round before half-time.
Mo Toure has had an excellent first haflf and he finds Andre Brooks who takes a strike from just inside the box which deflects inadvertedly off the heel of Ben Chrisene and into the roof of the net.
When it's going for you, it's going for you!
Valentín Castellanos (43 mins)
Hard one to take for Portsmouth.
They had just had a shot at goal up the other end and it's soon moved up the other end. Mo Kante is slick on his feet to keep the ball at his feet at the edge of the box and deliver in a cross for an unmarked Valentin Castellanos to dink into the goal.
Maybe this will bring the Hammers to life.
Callum Roberts (42 mins)
A day of shocks on the cards?
What a goal this is by Callum Roberts. He spins on a sixpence from Nick Tsaroulla's threaded pass towards the edge of the area before smashing a wonderful finish past Max Weiss.
With their first shot of the game, Notts County lead Burnley.
Derby 0-2 Lincoln
Almost a third for Lincoln at Pride Park and they really would have been in dreamland then.
It drops to Ben House at the back stick and his low drive is blocked. It then falls for Ivan Varfolomeev but his effort is also kept out by some last ditch Derby defending.
Not sure John Eustace will be massively pleased with his Rams side in this first half.
Leicester 1-0 Northampton
Tim Oglethorpe
BBC Radio Northampton commentator
If I was a Leicester City fan I would be having kittens!
They play the ball around the back, and have played it about three or four times across their own box.
It is close stuff - which nearly cost them a goal in the early stages of this game.
West Ham 0-1 Portsmouth
Paul Parker
Ex-QPR and Manchester United defender on BBC Radio London
I have to say that in a way Portsmouth deserve it because they've been industrious.
West Ham have got to have a shot on goal, put the goalkeeper under pressure. In the final third they've been absolutely awful.
The manager has got to spark it up at half-time. I'd like to see El Hadji Malick Diouf come on.
Radinio Balker (38 mins)
This seemed inevitable, really...
It was as cool as you like by Radinio Balker, who headed home a great cross from Lasse Sorensen on the right side.
The 10 men of Preston might need to shake things up a little.
West Ham 0-1 Portsmouth
Guy Whittingham
Former Portsmouth manager on BBC Radio Solent
Slight deflection on it I think, which wrong footed the goalkeeper, but it was a good strike from Adrian Segecic. Took it down on his chest and waited for it to drop for a half-volley.
QPR 0-1 Millwall
Time is running out for QPR as we head into the final 10 minutes of the 90.
Julien Stephan rolls the dice again as Amadou Mbengue and Paul Smyth are withdrawn.
On come Kealey Adamson and Koki Saito.
West Ham 0-1 Portsmouth
Dan George
BBC Sport at the London Stadium
Well what a big goal that is for Portsmouth!
Adrian Segecic ended last season in really good form and what a way to start things off in this campaign.
There was absolute pandemonium amongst the travelling support to my right when that went in.
Leicester 1-0 Northampton
Jon Guthrie heads wide for Northampton as they try to get back into the match.
A little earlier, Elliot List and Connor Lemonheigh-Evans linked up well to force a save from Jakub Stolarczyk.
They'll need something soon.
Leicester 1-0 Northampton
Jack Rafferty
BBC Radio Leicester commentator
The crowd are trying to push these Leicster players forward now.
We officially have our first, 'get it forward' of the season from the crowd.
QPR 0-1 Millwall
A double change for Millwall and it will be a debut for Kyrell Lisbie following his move from Peterborough.
Lisbie, the son of Kevin, replaces goalscorer Luke Cundle. Tairyk Arconte is also on for his debut as Josh Coburn makes way.
Adrian Segecic (33 mins)
Well, how's that for a turn up for the books?
West Ham defender Max Kilman makes a solid header to clear a corner delivery but Adrian Segecic controls it well with his chest just outside the box and lets loose with his left foot.
Kilman can't move out the way, seeing it deflect off of him to fly into the netting.
The travelling support will be as pleased as punch with how their team have performed so far. It's been a really good showing from them.
Swansea 0-0 Birmingham
Image source, ShutterstockBirmingham are still yet to take aim at goal but Swansea...
They've notched their efforts up to five as Joseph Opoku misses the net on the counter-attack. Only one of those has challenged Blues keeper James Beadle though and there's a few in that Blues team that can net a stellar goal from no where.
Burnley 0-0 Notts County
And now Burnley have a decent chance.
Zian Flemming hits a powerful drive back across the face of goal from the left, about 15 yards out.
But James Belshaw does brilliantly in the Notts County goal to parry it away.
Burnley 0-0 Notts County
Burnley have had a lot of the ball, with 77% possession. But as yet, just the one shot for the Clarets inside the first half an hour.
A very low-key affair in terms of chance creation so far.
Swansea 0-0 Birmingham
Gareth Vincent
BBC Sport Wales at the Swansea.com Stadium
Both sets of fans are enjoying themselves at the Swansea.com Stadium, with the mood light during the opening exchanges of the new season.
On the pitch there is energy and endeavour, with Swansea looking the more likely side to find a breakthrough so far.
Adam Idah shot too close to the goalkeeper, while Eli Just was a yard off target as he tried to steer a shot into the far corner on his debut.
Watford 0-0 Crawley
Crawley are cranking up the heat at Vicarage Road as Charlie Barker and Kellan Gordon both force saves out of Federico Ravaglia.
Watford head coach Alessio Dionisi will be getting a little uncomfortable at the sight of that.
West Ham 0-0 Portsmouth
Portsmouth's Zak Swanson goes for goal but he's off-balance and it's more in hope than anything.
It flies out for a goal kick but even as play resumes, West Ham defender Max Kilman is put under pressure.
There's a lot of people in that crowd but they haven't had much to please them thus far.
