It's interesting that Luke Charteris is on. 

If you're protecting a lead his work-rate is phenomenal.

I can save you some money on performance monitors. All the players are knackered and they've all given it everything.

Wales steal a line-out, the third they've managed to take tonight, as Ireland replace the excellent CJ Stander with Peter O'Mahony for the final push. 

Joshua Byers Warner: Wales need to put width on that ball! they are way too many of their players bundled together!

Kevin:  Dan Biggar is fairly unlikeable as a rugby player...in fact Wales moan a lot, collectively. #getonwithit, external

David Thackeray: Please somebody tell me what those little box things are between the player's shoulder blades.

We think they're performance monitors David...

Johnny Sexton tests Leigh Halfpenny with a high, spinning kick into the Cardiff night and the full-back doesn't take it cleanly. It goes backwards though so it remains Wales ball and they manage to kick it clear. 

George North's finish for his second try was a lot more straightforward than the first...

Wales have made 303 metres to 297 for Ireland. The Welsh have had one carry fewer - 112 to 113, but beaten one man more - 14 to 13. When it comes to turnovers it's nine by Wales, 10 by Ireland.

Of course the biggest gap is in the category that matters most - on the scoreboard.

It's amazing how Justin Tipuric just sees things happen quicker than everyone else.

He reads the game so well.

More dissent aimed at referee Wayne Barnes as Justin Tipuric is judged to have passed the ball from on the floor, the crowd thought it was an infringement by Rory Best.

There are still 20 minutes left. Some wrecked bodies out there. It's been a bruising, compelling Test match.

It's the right option. It would have put them two scores ahead and he'll be disappointed he hasn't made that.

It's a routine drop-kick for him after a lovely pass from Rob Evans.

But they shouldn't panic now. Don't look for the miracle pass and keep possession.

Unlucky Dan Biggar! He goes for the drop-goal, a lovely strike but it flies into the post and bounces clear.

Is that another turning point in the game, the championship?

Ireland are now within a converted try of the lead, and look the more dangerous side since Johnny Sexton emerged from the sin bin.

As I say that Wales have the crowd on the edge of their seats with a looping pass out to the left, the red drive is now on...

Sam Warburton is getting through so much work.

He's a nuisance at the breakdown and has made some phenomenal hits.

Johnny Sexton, with the left eye of a flyweight in the eighth round, lands a blow of his own, right through the middle.

Johnny Sexton, how he manages the whole of the Irish back-line, he makes a significant difference to this side.

Boos ring out as referee Wayne Barnes gives a penalty for a high tackle and Ireland will kick this time. 

It's a penalty to Ireland in the end after all that for a knock-on. Wales would probably take that - but Ireland kick into the corner.

Another big test coming up. 

That's 22 phases for Ireland, 23 with Sean O'Brien. Ireland are right under the Welsh posts.

Twenty-five phases...

A big examination of the Welsh defence, George North coming to the party at both ends with a swallowing hit on Simon Zebo. Still Ireland come though.

A lovely long miss pass from Garry Ringrose to Keith Earls adds some much-needed impetus to the Irish attack as they then sweep down their left flank. 

Johnny Sexton pops the passes away, Ringrose then running and finding Donnacha Ryan into the 22. Irish momentum.

A very different Wales team this week. 

They're mixing the best of their old game with their new. 

They're holding onto the ball, going straight and taking Ireland through lots of phases. It's tiring, it's exhausting.
