The have to take one of these opportunities, Scotland.

They once again lose the ball by splitting their attack - they need to work as a 15 more.

Makazole Mapimpi returns from the bin so it's 15 v 15. Grant Williams is on at scrum-half for South Africa, while Jamie Dobie is also on at nine for Scotland. Ben White departs.

It's tense.

Scotland have ball in South Africa's 22.

Some ferocious Springbok defence forces a turnover. This has the air of a near miss about it. Will Scotland prove me wrong?

One of the best clutch kickers this game has ever seen just doesn't miss those.

South Africa have their first points of the second half and it's a seven-point game again.

Yep, another South Africa penalty. An arm was taken in the air at the lineout by Matt Fagerson. Tight call, but loose from Scotland.

Handre Pollard is lining up a kick to goal.

You feel like South Africa know what to do in these situations. Lukhanyo Am draws a penalty and Handre Pollard boots it 40m down the pitch.

Josh Bayliss is on for Scotland, who have emptied their bench as well.

Scotland have rattled South Africa. Decisions are starting to go their way. But they have to keep chipping away and turn pressure into points.

South Africa are going to close up shop now.

They will try to be really physical, force penalties and get territory that way.

The simplest of kicks for Finn Russell. He's five from five, and this game is coming alive.

Final quarter, who will step up?

Scotland are starting to motor.

But their composure is letting them down at the last moment. Huw Jones puts in a phenomenal break but is hauled down. Scotland then get forced back.

It goes to the other side and Finn Russell puts in a through the legs pass! Mapimpi is penalised for a deliberate knock on and goes to the bin.

Breathless.

Scotland fire a shot. But it ends with a Matt Fagerson knock on in front of the posts.

It's a lovely offload from Zander Fagerson to put Duhan van der Merwe through a gap, and somehow Eben Etzebeth gets back to flatten the Scotland wing.

Scotland still motor forward before Fagerson lets it slip through his grasp as Jasper Wiese flies up to hit him.

South Africa follow it up with a scrum penalty.

This game is really in the balance, and Scotland's attack has yet to really fire a shot.

That is a positive for Gregor Townsend, but there's also the fear the Springboks stop making so many mistakes and seriously click.

Scotland have a lineout just over the halfway line.

Another South Africa knockon gives Scotland a brilliant counter attacking chance. It's moved right to Blair Kinghorn, who grubbers through.

Willie Le Roux dives on the ball, and then Kinghorn dives on the full-back to give away the penalty. That's such a poor decision from the Scotland wing.

He gives the Springboks an easy out.

South Africa get a free kick at the scrum and try to wrap around the back of the Scotland defence.

Lukhanyo Am was involved, but the final pass lets them down. The Boks come back the other way, but there's a knock on.

South Africa are getting frustrated because Scotland are competing so well at the breakdown.

Here comes the Boks bench...Siya Kolisi, Pieter-Steph Du Toit and the rest. Eben Etzebeth is the only starting forward left.

Amazing. Anyway, it kicks off at a maul and Etzebeth is penalised for pushing Zander Fagerson to the ground. The giant lock then wins the lineout anyway...

An easy one for Russell from right in front of the posts.

It came after a scrum penalty, which is a real fillip for Scotland at the start of this second half. It's a seven-point game.

We're back under way at Murrayfield. Can Scotland find a response?

A good start as the Boks knock on from the restart.

RG Snyman has replaced Franco Mostert in the second row for the world champions.

For anyone scratching their head about Scotland still having 15 men on the pitch despite Scott Cummings' red card, let me explain.

There is a new law which is being trialled in these Autumn games in which a player can now be yellow carded, red carded, or a new 20-minute red card applies.

The latter means the offending player cannot return, but after 20 minutes they can be replaced. It's designed to punish dangerous play short of serious foul play, roughly speaking.

So Max Williamson has come off the bench to make it 15-a-side once more.
