Malcolm Marx is getting checked over by a Bok medic.
A break in play and a chance to tell you about the shirt numbers worn by the South Africans today.
Each one contains a collage of portrait shots of former South Africa wing and 1995 World Cup winner Chester Williams who died earlier this month.
New Zealand 0-3 South Africa
And now the All Blacks comes under the pump at the scrum.
The South Africa front row, the sort of props that could hold up a pit tunnel nevermind a scrum, send them backwards and Aaron Smith has to hurry some untidy ball out to Richie Mo'unga.

The ability to hang on to the ball is going to be really key in this game. Neither side is making an inch right now.
New Zealand 0-3 South Africa
New Zealand flanker Sam Cane took a knock there but is good to continue. Shannon Frizzell is the backrow cover on the bench.
New Zealand 0-3 South Africa
Aaron Smith is looking like he is still getting the jetleg out of his system.
The New Zealand scrum-half was under no pressure at the base but threw a nothing pass to no-one.
Frankly the champions would probably take a three-point deficit at the moment.

Under a lot of pressure at the moment, New Zealand - they're making some mistakes early on. Aaron Smith had no protection to get his kick away there and Verrmeulen came through for the charge down. They're a bit rattled.
New Zealand 0-3 South Africa
New Zealand scrum-half Aaron Smith is half charged-down by Franco Mostert!
Momentary panic in the New Zealand defence.
But Sam Whitelock earns a penalty with a strong body position at the resulting breakdown.
His team needed that.
New Zealand 0-3 South Africa
Faf de Klerk puts up a laser-guided box kick and New Zealand wing George Bridge fluffs the take, bobbling the ball into the mitts of Boks hooker Malcolm Marx.
Willie Le Roux flings the ball wide to Makazole Mapimpi out wide. The Boks bristling with danger. That ball has gone forward from a green hand.
But South Africa are enjoying the best of the early exchanges.
New Zealand 0-3 South Africa
South Africa scrum-half Faf de Klerk looks like Goldilocks encountering the full extended Bear family as he wanders about between the two monster packs.
A clever nudge from Lukhanyo Am forces Beauden Barrett to carry the ball over the touchline and concede the lineout midway through the All Black half.
New Zealand 0-3 South Africa
The first test for South Africa's diminutive wing Cheslin Kolbe in the air.
And he passes! Claiming the mark with the sounds of Anton Lienert-Brown thundering up at him.
New Zealand 0-3 South Africa
Gareth Lewis
BBC Radio 5 live commentator in Yokohama
New Zealand have never lost a pool match at a Rugby World Cup remember.
South Africa, famously, lost to Japan in the 2015 World Cup in the Miracle of Brighton.
Handre Pollard
A monster boot from the Springbok 10. And dead-eyed accuracy with it.
First blood Boks and a warning that All Black discipline needs to be drum tight.

A frenetic, frantic start.
Handre Pollard fluffs an early gather in backfield, allowing the ball to dribble through his legs.
South Africa tidy up and hoist a high one. New Zealand wing George Bridge claims it but Stephen Kitshoff earns a penalty on the floor.
Handre Pollard is lining up the shot at goal....
New Zealand 0-0 South Africa
Deep breath. Stomach in. Chest out. On your marks. Get set. Go!
Jerome Garces toots the starting whistle and Beauden Barrett boots high into the Yokohama night.
Claimed safely by Pieter Steph Du Toit.

I haven't seen Kieran Read move in the haka before. He hasn't been in the best of form coming in to the tournament but he wants to lead from the front. Outstanding.

Andrew Priestley: The rankings might not reflect it, but these are the best two sides in world rugby. Of all the world class talent on the pitch I have a feeling it will be the man with the whistle who will have a big say on the outcome of the game. There’ll be a BIG call or two to make.
New Zealand v South Africa (10:45 BST)
TJ Perenara leads the New Zealand haka.
And the replacement scrum-half gives it full beans - eyes popping, tongue poking and oozing Maori mana.
The gauntlet has been slapped down with relish.
Kick-off is next.

This is BBC Sport's Alex Bysouth on a busman's honeymoon.
Breaking with BBC impartiality rules in that All Blacks top, he looks the split of crocked full-back Damian McKenzie.
Hope you packed your boots Alex.

South Africa Duane Vermuelen does a last little piece of diplomacy, shaking the hands of each of the three on-field officials.
Meanwhile Kieran Read leads his men down the tunnel at David Sole speed.
Out on the pitch Sonny Bill Williams offers a prayer before the national anthems strike up.
