Another knock-on from the luckless Elton Jantjies.

The Springbok fly-half allows the ball to flop forward out of his grasp to ironic cheers from the stands.

Josh Navidi, who has been good today and across the autumn, gets the hook.

Dan Lydiate is on for the final six minutes.

Elton Jantjies, fresh off the bench for the Boks, knocks on in the shadow of the sticks.

Rhys Webb puts boot to ball and play is reset back at the halfway line.

South Africa have the heavy brigade rumbling.

Forward biff takes then up to within 15 metres of what may well be a killer score.

And a change at 10 for the Springboks.

Off comes Handre Pollard and on comes the free-runing Elton Jantjies.

Malcolm Marx gets a taste of his own medicine as replacement Wyn Jones strips the ball off the isolated Bok.

That, along with a monster Hadleigh Parkes punt, eases the pressure with the visitors just outside the Wales 22m.

Trevor Nyakane is on for Wilco Louw in the Springbok front row. Will that dent their scrum dominance?

They've worked hard for that penalty. They have their noses in front now.

But there's still plenty of time left for South Africa, Pollard loves a drop goal, doesn't he?

Over it goes.

Wales a nose ahead with 12 minutes to go.

Josh Navidi breaks the gainline and Pieter Steph du Toit is the wrong side at the breakdown and fails to make an effort to roll away.

Up pops Jerome Garces penalty arm.

This should be three. Leigh Halfpenny lines it up...

The Millennium Stadium crowd are baying as Alun Wyn Jones takes the ball cleanly in the line-out and the engine fires on the Welsh drive.

But the South Africa pack soak up the momentum and keep the ball off the floor as the two packs come to standstill, five metres short.

Scrum to the Boks and a chance to clear the lines...

Elliot Dee, on at hooker for Kristian Dacey, tramples up to 35m out from the South Africa line.

We are coming back for a penalty to the hosts though. No clear advantage apparently.

Halfpenny sizes up the shot at goal and opts to wallop towards the corner instead.

Wales with the throw, 12 metres out...

Now it's the Springbok fans who are making the noise in Cardiff.

As comebacks go this is right up there, and Welsh fans are wondering what's happening

Wales start making inroads into the South Africa half, but then the ball bounces forward off Cory Hill's paw.

The Boks now looking to build...

That's much better from Wales.

Wales get a desperately-needed foothold.

Aaron Shingler wins a grapple-fest with Daniel du Preez at the breakdown to turn over the ball on the red 22m.

Rhys Webb has come on for Aled Davies at scrum-half by the way.

Brian Moore
Former England hooker on BBC One

Wales have been made to pay for their complacency.

If Wales don't get stuck in now, they will be looking at a shameful defeat.

Handre Pollard's laser-like touchline boot splits the sticks and Wales, 18 points ahead after 35 minutes, are behind.

Jonathan Davies
Former Wales international on BBC One

South Africa, after a shaky start, have definitely upped their game.

They performed in patches in the first half but in the second half, they're determined to finish the tour with a good result.
