Former Wales lock on BBC Radio CymruWales will think about changes quickly after the break. We might see Wyn Jones early because Rhys Carre still has five minutes left in the bin. The bench will be important because there'll be some tired legs out there and we don't want to see Wales falling off tackles late on like they did last week.

Former Wales wing on BBC Radio CymruIt's a first-class Test match. South Africa, with their powerful, physical players are asking big questions but Wales are soaking up the pressure and throwing everything at the Springboks in return. Can Wales though sustain this tempo for another 40 minutes?

BBC Sport Wales at Principality StadiumWales have been much sharper than many anticipated, with Dan Biggar pulling the strings in attack and kicking four penalties.
Flanker Ellis Jenkins has been influential on his first international in almost three years with crucial defensive interventions in some excellent resistance from the home side.
Fly-half Handre Pollard has responded with three penalties for South Africa.
Both teams have been handed yellow cards with props Ox Nche and and Rhys Carre both being sent to the sin-bin.
An attritional first 40 minutes will surely just continue in the same manner in the second half.

Wales 12-9 South Africa
It's been a dogfight in wet conditions under the open roof of the Principality.
Both sides have conceded their fair share of penalties, as a result both have a man in the bin.
South Africa’s imposing bench is likely to make an enormous difference in the second half.

Chwaraeon BBC CymruWales need a big effort now before the break. They're conceding penalties at will and Rhys Carre almost got away with it but the referee was ultimately right to show the loose-head a yellow card there.

South Africa are down to 14 men, but you wouldn't think it.
Damian de Allende shows his attacking threat with a storming run from the centre, with Makazole Mapimpi also getting involved on the wing.

Former Wales lock on BBC Radio CymruSouth Africa's ill-discipline has been a real theme in this opening half-hour and they should have a couple of players in the bin really. Ox Nche deserves to see yellow but Duane Vermeulen is lucky not to join him.

Dan Biggar deserves credit for the way he's managing this game.
He points to the posts and extends Wales' lead.

The officials are looking at some potential foul play here.
Ox Nche is under investigation for a stray arm to Nick Tompkins' head.
The referee Paul Williams is happy he was going for the ball though.
But there's another offence...

Louis Rees-Zammit is screaming for it on the wing, but it's the forwards trucking it up.
