Prendergast almost breaks through but he's brought down five metres out...and Argentina counter ruck to steal possession!

They are on their own line but that's a massive moment!

Ireland still have it in the 22 but Argentina are holding firm!

Ten minutes to go!

It's turned into a maul and Ireland are creeping closer to the line!

This place is electric. The crowd know how big a period this is.

Here come Ireland as Hugo Keenan is chopped down, but play is brought back for a penalty as Argentina stray offside.

They're going to tap and go.

Her'es the moment for Cian Healy as he puts his name in the Ireland rugby history books.

A massive congratulations to Cian! What a servant.

Sam Prendergast has one of those faces that makes you go, 'blimey, I feel old'.

He sends a solid kick into the 22, and Ireland have the line-out in a good position.

He is such a top talent and won't feel the pressure but introducing Sam Prendergast in such a tight game perhaps isn't ideal.

However, Andy Farrell clearly has faith in him.

Ireland win the penalty from the scrum and Clarkson is getting plenty of pats on the back after a huge drive.

After Tom O'Toole was forced off after a few minutes last week, now Ryan Baird is heading down the tunnel moments after coming on.

Peter O'Mahony is on in his place.

Thomas Clarkson puts in a crucial hit on Albornoz, which puts the fly-half off balance and James Lowe forces a knock on.

Scrum Ireland just inside their own half, with 16 minutes left.

It's sent into touch as Rob Herring is introduced in place of Ronan Kelleher.

Argentina win the penalty from the scrum and there's a few afters as the forward packs get to know each other that little bit better.

No harm done.

Some time for Sam Prendergast to be thrown into the Test arena for the first time.

There's a fair bit of uneasiness in the crowd right now, and rightly so...

Here comes Sam Prendergast for his first, and I suspsect not his last, Ireland cap.

The 21-year-old is tipped for a big future, and he's on for Jack Crowley, and this is a huge ask to see this one out with 18 minutes left.

Jamie Osborne is also on for Henshaw, while Ryan Baird replaces James Ryan.

The fine margins at this level.

Robbie Henshaw jumps to gather a kick outside the Argentina 22, but it just slips through his fingers.

So close to perfection.

Albornoz kicks is straight to James Lowe, and he brings it into contact midway through the half.

Can Ireland build something from here?

Now Ireland are looking to build some much-needed momentum here as they go through the gears.

Jack Crowley dinks it through and it's into touch in the 22, as Joe McCarthy returns to the pitch.

The knock-on from Argentina saves Ireland but there is some brutal defending from Argentina there.
