Robbie Henshaw puts in a big tackle for bring down Santiago Chocobares, who had found himself in space with a great line.

Argentina are piling the pressure on, and have a penalty advantage after a high tackle.

That was just too easy for Ireland, and so poor from Argentina.

Sam Prendergast's try has secured the bonus point for good measure.

Ireland have looked really good in that half and we have seen good variation. If they continue like that they will be hard to stop.

Off we go for the second 45 minutes.

Leonel Oviedo is back on for Argentina, so they have a specialist hooker back on the pitch.

The players are back out in Dublin, and it won't be too long before we are back under way.

On the naughty step.

Argentina will have the chance to regroup at the break, but they will start the second half with 14 players after Justo Piccardo's yellow card.

The back three of the returning Mack Hansen, Rob Baloucoune and Hugo Keenan have been good to watch so far.

Is this Ireland's best combination?

What did you make of the opening 40 minutes in Dublin?

That'll be that for the opening 40 minutes.

Argentina started well but Ireland responded with three good tries.

There's a bit of confusion as Boris Wenger looks a bit bemused after he's told he has agreed to play hooker, and this scrum will be contested.

Argentina manage to win a penalty and can finally relieve some pressure.

We're another hooker down here.

Leonel Oviedo, who replaced Julian Montoya, is now off for a HIA too.

Argentina now have to bring prop Mayco Vivas is on for this scrum, which will be uncontested.

Ireland will have another line out five metres out, but skipper Dan Sheehan is off for a HIA and Ronan Kelleher is on in his place.

His first throw is decent but Argentina knock it on in the air, so Ireland will have a scrum.

We're now looking to see Oviedo infringed before Sheehan was put into touch.

Luke Pearce says he didn't allow Sheehan to get back to his feet, and he gives away a penalty.

It could be a penalty try but it would be very harsh.

Close!

Ireland's maul is doing damage and Dan Sheehan is almost over in the corner.

Gonzalo Garcia does really well to break his stride and his foot does go into touch, so this won't count.
