If I'm honest, I can't see why Ben Thomas was shown a yellow card.

If someone tackles you and is holding onto you like that, it's only natural that you're going to try to get them off.

If you're just trying to get your leg free and there's no contact with the head or the body, then you've not done anything wrong.

The key thing was that they couldn't see any contact with the head, so I can't understand why they've sent him off the field.

Ben Thomas is back on the pitch.

The jury is still out on whether it should have been a straight red because of the intent, just a yellow because there was no contact or actually whether he should have been penalised at all given he was being held.

Interesting one.

We're back under way.

Can Wales comeback a second time?

There is much more riding on this game than Wales trying to break a home losing streak and Argentina seeking another Six Nations scalp.

There are a mere 24 days until the draw for the 2027 World Cup is made in Sydney and both these sides are standing on a cliff edge in terms of where they will be seeded on 3 December.

Teams will be drawn in six groups of four teams with the world's top six teams all kept apart.

Argentina - sixth - are on the edge of being among the top tier and thus avoiding the world's best teams in their pool but have Australia right on their heels with less than a point separating them.

Wales are 12th and would be in the second pot of teams if the draw was made today but their World Cup pool fate is almost certainly going to be shaped over the next two games with next week's opponents Japan breathing down their necks.

A win today or next week should secure them a seeding in the second band but defeat by Japan will surely mean a ferocious pool for them in 2027. For example, they could be drawn in the same pool as world champions South Africa and hosts Australia.

A win or draw today will be enough for Wales to move above Georgia into 11th.

Clear?

Wales looked a bit edgy on the wings, especially Tom Rogers' side and Blair Murray is having a tough afternoon in the air.

But Wales settled things right down. The last score was a complete opportunist try after being disrupted with a yellow card, it was a bit of world class play.

But from a Wales point of view they fell asleep on that defensive set. It's so important, they've just scored a try and then they open up and give them another.

But some really really good signs for Wales in that first half.

They've got to come back out and give another good account of themselves. The first t10 minutes are crucial.

International life is set to begin at 31 for Olly Cracknell after the back row was rewarded for his perseverance – and physicality – with a place on Wales' bench today.

Cracknell initially missed out on Steve Tandy's squad for the four November Tests but then Taulupe Faletau suffered a knee injury.

Impressive Prem form earned the Leicester man a call-up and Cracknell is poised to make an impact off the bench against the Pumas.

It will be a rise to international level for a hard-working, no-nonsense forward who arrives at Principality Stadium via Rygbi Gogledd Cymru (RGC) in Colwyn Bay, Ospreys, London Irish and then, after the Exiles' financial collapse, Tigers.

The back-rower's reward for plugging away will come on Sunday when he becomes the 1,216th player to represent his country.

Cracknell edged out 20-year-old Morgan Morse to face the Pumas and will be keen to make an impression in the countdown to the 2027 Rugby World Cup.

"When we named the team on Monday and Olly was announced you see the emotion," said Tandy, who coached Cracknell at Ospreys.

"I felt emotional seeing someone who's gone on such a journey to get that opportunity later on in his career. I think it's an amazing story."

Argentina came here and have shown what they wanted to do.

They have a strong kicking game and have won that battle over the course of the 40 minutes.

What would have disappointed Steve Tandy is that he would have spoken with his players before the game about discipline.

There have been some cheap penalties being given away that have handed opportunities for Argentina to attack.

The game started with a really soft try to give away.

Before the game, what you wanted to see from Wales was not conceding any easy tries.

There is a missed tackle that leads to the try and Wales will be so disappointed to concede twice just before half-time.

That's the end of a pretty breathless first half.

I don't think anyone inside the Principality Stadium can complain they haven't been entertained with six tries.

Unfortunately for most of the fans here, four of those have come from the visitors!

Wales worked hard to get back on level terms at 14-14 through Tomos Williams and Dewi Lake.

But Argentina have that ability to score something from nothing.

Discipline is killing Wales at the moment. When Argentina are close to the try line, that's when Wales are giving away penalties.

You can see what they're trying to do in slowing down Argentina's play but you have to put in some dominating tackles.

We've just been told Ben Thomas' yellow card will remain a yellow.

He's a little fortunate.

The last five minutes of this half are going to be massive.

Wales cannot let Argentina score, but if they can go down the other end and get some points before half-time, it would be a huge boost.

Argentina's off-loading is impressive but they're being met with some equally impressive Welsh tackling.

Wales fans... liking what you're seeing so far?

Thumbs up or down.

Ben Thomas' yellow is still being reviewed and I think he could be in trouble.

The fact he doesn't quite makes contact with Matera's head is the only thing that is saving him right now.

But we'll wait and see.

Wales clear the initial danger but give away a penalty 30 yards up field that the full-back strokes between the posts.

Pumas back in front.

That was so important from Jac Morgan.

After battling back to bring the score level, twice now Morgan has saved his side in his own 22.

He was quick enough to see that he could go for the ball.
