The scrum stays up and the Sigma Lions go right.

The tourists are holding them up though and even manage to push them back a couple of metres. Everyone is getting stuck in.

The two sides are struggling to make a scrum stick at the moment.

While we wait for that, here's a reminder of some of Chris Harris' hard work in the lead-up to Louis Rees-Zammit's try.

Hamish Watson is ferocious out there. He's defending with all his might but the Sigma Lions get yet another penalty.

A solid drive from the line-out and the Sigma Lions are just a few metres away now.

It would appear the Lions' defence isn't quite as good as their attack as the hosts barrel their way to within 10m of the tryline.

The Lions give away another penalty and Jordan Hendrikse kicks to the corner again.

Well, well, well...

The British and Irish Lions concede their first penalty of the match and their opponents kick to inside their 22.

Jordan Hendrikse thinks he's seen some space behind but Stuart Hogg says no.

A bit of kicking back and forth ends as Finn Russell tries to poke the ball over to Josh Adams. It's not on this time, but a glimpse of what we might get later.

Kyle Sinckler mistimes his run and knocks on.

NOW we can breathe. Scrum to the Sigma Lions.

The British and Irish Lions are not taking a breath.

Ali Price puts up a box kick and his team-mates collect in the hosts' half.

The ball goes into touch and we can all finally take a moment to breathe. Oh wait, no we can't. The Lions are off again at lightning-quick pace.

The Lions are back in the opposition 22 again.

Ali Price takes a quick penalty and they are 5m out.

Stuart Hogg stays down after landing awkwardly on his ankle after taking a high ball which is not what any of us want to see after the loss of Alun Wyn Jones and Justin Tipuric last week.

Remain calm, though. He gets back up eventually and will play on.

Elsewhere, Wales have hammered Canada 68-12 in their opening Test of the summer, scoring 10 tries in front of fans at the Principality Stadium.

Two tries apiece from Tomos Williams, new cap Taine Basham and Jonah Holmes and further scores from James Botham, Nicky Smith, Elliot Dee and Will Rowlands sealed the record points win over the visitors.

Fly-half Callum Sheedy added 14 points.

But Wales full-back Leigh Halfpenny suffered a serious injury to his knee less than 60 seconds into his 100th international cap.

Speaking of youngsters... a debut try for Louis Rees-Zammit?

Not to be. The cross-field kick goes a bit too far and the Wales wing can't get things off to a perfect start.

Still, the British and Irish Lions have made a pacey start.

The South Africa tour is go.

Sigma Lions youngster Jordan Hendrikse gets things under way.

The Lions run out into Ellis Park.

It really does hit you how sad it is that this is being played without fans. They should be greeted by the roar of those who have travelled the world to be there with them.

Nevertheless, Stuart Hogg looks well up for this.
