Now it's Charlton keeper Dillon Phillips to pull off a fine save to deny Jed Wallace at close range after he's played through by a lovely ball through the Addicks' defence by Ryan Woods.

This is better.

Macauley Bonne has almost singlehandedly wrestled Charlton back into this game.

He's played through on goal and almost slips a low shot under Millwall keeper Bartosz Bialkowski but he's on hand to make the save.

Another frustrating moment for Fleetwood as Wes Burns finds space down the right and fires across a dangerous looking cross.

But, there's nobody there to meet it in the Wycombe area and it sails all the way out for a throw-in on the opposite side.

Considering the bright start Charlton had, it's been all Millwall since about the fifth minute.

Just under 15 minutes remain of this first half and as yet, it's been short on clear chances for either side.

Jayson Molumby goes into the book for a high arm on Albie Morgan in an aerial challenge for the ball.

Charlton midfielder Morgan is down and receiving treatment in the aftermath and goes to the sidelines for a further once over.

Well, by this time in the first half - we'd already had three goals!

No more added so far as Fleetwood show some fight coming forward but already you can see how easy it is for Wycombe to soak up the pressure against a side chasing the game and with a man advantage as well.

Jed Wallace sends a long Millwall free-kick into the Charlton box.

However it sails past a crowd of heads and is nodded away by the hosts for a throw-in.

Fair to say this isn't a classic.

Another Millwall corner heads into the Charlton box and it pinballs around a succession of defenders.

Millwall keep it alive and deliver a further cross to Matt Smith who draws a fine save from Charlton keeper Dillon Phillips.

Back under way....

Callum Connolly, who was walking a bit of a tightrope on a yellow card for Fleetwood, is replaced by Kyle Dempsey for the hosts in the only change at the break.

Not long to go now until they resume on the Fylde coast.

Fleetwood in need of a bit of sea air to inspire them you feel for a comeback in this second half to keep their hopes alive in the tie....

Darren Pratley is called into action as the Charlton defender concedes another corner to the visitors as they continue their push to break the deadlock.

Jed Wallace delivers it towards the head of Matt Smith at the far post but yet again Charlton clear.

Better stuff from Millwall now as Jed Wallace forces Albie Morgan into conceding a corner after his dangerous run towards the Charlton box.

Millwall have scored the joint best amount of goals following corners this season with 13 but this time the set piece is well dealt with by Charlton.

Earlier on, the first of the two League One play-off semi-finals finished all square after the first leg as Portsmouth and Oxford United could not be separated at Fratton Park...

While we look back on the crazy events in that first half at Highbury and wait for the players to return for the second 45 minutes, we'll just catch up with how the other tie in League One went....

Jed Wallace launches a free-kick into the Charlton box and his Millwall teammate Matt Smith gets onto it.

However he heads over the crossbar from close range and the hosts live to fight another day.

Fireworks have been let off outside The Valley! But it's still too light outside to be able to see them.

However they are causing an almighty racket as the game continues underneath.

This is the most exciting thing to happen in this game so far to be fair.

Millwall make their first attack deep in the Charlton half and Jed Wallace picks up possession just outside the box.

The ball bounces following his attempt to get a shot away and Charlton clear their lines.

Not as an exciting start to this game as we had at Highbury!

Charlton have kept possession well at the start of this game and are passing the ball around the field nicely.

The game has calmed somewhat now that Millwall have eased their way in and they look happy enough to sit back as the hosts push on.

Well, well....

You will wait very many years to see a first-half more eventful than that one in football. Three goals in the opening six minutes, a missed penalty, a red card to Fleetwood and then a fourth goal on the stroke of half-time.

Incredible.
