Play has resumed, and Seoposenwe is back on - for now.
Netherlands 1-0 South Africa
Jermaine Seoposenwe has gone down again. She is not a happy bunny.
South Africa manager Desiree Ellis is issuing furious instructions on the sideline, she wants a lot more from her team.
Netherlands 1-0 South Africa
South Africa are struggling to keep possession, giving the ball back to Netherlands as they try and up the tempo of this match.
Lineth Beerensteyn is almost played in but the through ball is cut out.
Netherlands 1-0 South Africa
Jermaine Seoposenwe got a knock during that scramble, it looks like she was caught by her own team mate Bambanani Mbane in the desperate South African attempts to clear.
She looks very unhappy, an early change might be needed.
Netherlands 1-0 South Africa
Netherlands hunt a second as South Africa are sloppy at the back.
Lieke Martens has a shot blocked amid a chaotic passage of play in the South African box.
Netherlands 1-0 South Africa
This Dutch back three of Sherida Spitse, Stefanie van der Gragt and Dominique Janssen have a remarkable 424 caps between them.
Just the sort of experienced defence you want to see out a World Cup knock out win. Although they have been tested by Thembi Kgatlana so far.

BBC Sport at Sydney Football Stadium
It's a novelty to be watching a football match in the daylight here in Sydney, with the match kicking-off at midday.
Most matches have been in the evenings to cater for the various time zones watching the Women's World Cup across the globe.
It's a pleasant day after some heavy overnight rain and there is certainly a zip to the surface.
Netherlands 1-0 South Africa
A good response from South Africa then, who have been further hamstrung by the absence of captain Refiloe Jane today.
The players held up her shirt for their pre-game photo, their skiper in their thoughts.
Netherlands 1-0 South Africa
That is how South Africa respond!
Thembi Kgatlana again runs direct at the defence and shoots from a tight angle, which Daphne van Domselaar does well to tip over.
Somehow the officials missed that touch, and a goal kick is given.
Netherlands 1-0 South Africa
So how can South Africa respond?
This is their first ever World Cup knock-out match, and conceding an early goal to quality opposition was not in their plan.
Jill Roord (9 mins)
From the resulting corner, Netherlands lead!
Lieke Martens meets it with a near post header which is half-cleared off the line, the ball spinning into the air.
Jill Roord is first to react and nods the ball home from close range. It's her fourth goal of the tournament.
Netherlands 0-0 South Africa
What an effort by Esmee Brugts!
Having scored two stunners against Vietnam, she curls one towards goal from wide on the left.
It is dipping over keeper Kaylin Swart, who does well to tip it over.
Netherlands 0-0 South Africa
Netherlands respond, Danielle van de Donk wins the first corner of the match.
It is headed clear.
Netherlands 0-0 South Africa
South Africa burst into life and have the first shot of the game.
Thembi Kgatlana is set free through the middle of the defence, however her effort lacks conviction and is straight at the keeper.
A shot across the bows for the Dutch.
Netherlands 0-0 South Africa
This is the first game in Australia for both of these sides. They each played their group games in New Zealand.
Both will hope to be back on Sydney in the future - the final is played here on 20 August.
Netherlands 0-0 South Africa
A quiet start here. Netherlands keeping possession, South Africa happy to sit a bit deeper.
Expect this to be the pattern for most of this match.
Netherlands 0-0 South Africa
This is the final game at Sydney Football Stadium this tournament.
This arena has seen some sensational moments, from Colombia's late win over Germany to Marta Cox's free kick for Panama against France.
All the future games in Sydney at this World Cup will be played at Stadium Australia, including the final.
Netherlands 0-0 South Africa
Here we go!
The players are on the pitch, the anthems have been played.
Kick-off is moments away.
Netherlands v South Africa (03.00 BST)
Rachel Brown-Finnis
Ex-England goalkeeper
South Africa have done brilliantly to reach the knockout stage for the first time at a World Cup and their group was another one that was so exciting - it was in the balance until the very end.
Banyana Banyana have scored at least once in every game so far, including against Sweden, and I am backing them to do the same here.
But I have to go with Netherlands to go through. The Dutch seem to have found some form at exactly the right time.
Brown-Finnis' prediction: 2-1
