On the ref's mic we can hear that Peter O'Mahony is absolutely livid with that Lavanini hit on Cian Healy.

Rightly so. That's ridiculous from the second row.

Twenty minutes to go.

Ireland are not happy with Tomas Lavanini.

"He knows exactly what he's doing!" screams Peter O'Mahony, and this will be reviewed.

Another Ireland line-out and they're camped on the Argentina line!

The Argentina penalty count is creeping up as they battle to keep Ireland at bay. Harry Byrne sticks one in the corner and Ireland have been dangerous from those line-outs today.

Can Ireland step on the accelerator while Argentina are down to 14? The hosts are trying their best, but at the moment being repelled by a grafting defence.

Ignacio Calles puts on his best innocent face after wandering over and clipping Joey Carbery with a sly elbow to stop the fly-half's kick chase, but the Argentina forward wasn't getting away with that one.

Simple for Joey Carbery and he stretches Ireland's lead to 20 points.

Peter O'Mahony gets a talking to, while we're going to the video to see if Pablo Matera made a deliberate knock-on to halt Ireland's attack a moment ago.

And the Argentina number eight is yellow carded. The visitors are down to 14.

That Ryan Baird carry the first real bit of quality in the first half. Serious athleticism from a second row - who only found out he was playing this morning.

Argentina have been seriously wasteful, two crooked line-outs in Ireland's 22 within minutes of each other.

Hello! What a break from Ryan Baird, the big lock goes bounding up field before finding a blue and white arm wrapped around his leg.

Ireland keep it moving but it's good scrambling defence from the visitors.

Argentina are still coming at Ireland, and they win a penalty inside the 22. Sticks? Nope, they want the try... line-out in the corner it is.

Plenty of grunt from the Argentine pack as they try to smash a way through the Ireland defence, but that wall of green is standing firm and Tadhg Furlong thuds into a huge tackle to take any momentum out of the Pumas' attack.

Injury worry for Argentina early on, it looks like Guido Petti is getting some treatment - he's up and the visitors have a penalty. Santiago Carreras sticks it in the corner this time.

Ok, away we go!

So Ireland head into this second half looking to make it eight wins on the bounce.

Big 40 coming right up.

It's been a decent first half for Joey Carbery at fly-half, he has nine points with the boot and a 100% success rate so far.

That's the break.

Ireland have rode their luck at times but will be happy with that scoreline.

Can Ireland make Argentina pay for those missed points? They're building some pressure on the Pumas' line...
