You hope Johnny Sexton is OK. The protocols are in play and they will look after him.

Former Wales back-row and golf-cart aficionado Andy Powell is impressed with some of the shifts put in.

Johnny Sexton goes off with that head injury and Billy Burns comes on in his place.

Ireland really have to look at their line-out with the overthrows. I know they've brought Paul O'Connell in, so maybe he can give them some tips.

Ireland have their longest spell of possession for a while, midway through the Welsh half.

Wing James Lowe almost bursts through but is gobbled up by an increasingly organised and abrasive Welsh defence.

With the Ireland attack running out of steam, referee Wayne Barnes stops the game so Johnny Sexton can receive treatment.

The Ireland fly-half's head seemed to accidentally catch the knee of Justin Tipuric on his way down in a tackle.

Mistakes are creeping into the Irish game now, maybe a bit of tiredness.

They've played with great intensity down a man.

Getting two scores ahead with 15 minutes to go is massive. Ireland now have to force the game and when you do that then you will make mistakes. That could creates more opportunities for Wales. Ireland have to take any chance that comes their way.

Wales are two scores clear with a quarter of an hour to go.

The 14-men of Ireland haven't laid down, they've battled all the way, but Wales could just have their hands on the victory.

Changes for Wales, with props Rhodri Jones and Leon Brown replacing Wyn Jones and Tomas Francis, while Callum Sheedy - a fly-half - is on for wing Hallam Amos.

A collector's item: a solid Wales line-out, and with a decent move too, Alun Wyn Jones peeling around the back to set an attack in motion.

Ireland are penalised at the ruck and Leigh Halfpenny has an easy kick in front of the posts to add to Wales' lead.

Halfpenny puts it over and Wales are now more than a converted try ahead of Ireland.

Are Ireland just starting to tire a little? Is the effort of playing with 14 men for so long beginning to catch up with them?

Wales have a chance to extend their lead, after Ireland's Conor Murray is penalised for blocking Louis Rees-Zammit and stopping him from competing for a high ball.

Wales kick to touch, up to the Irish 22.

What a moment for the 20-year-old on his first Six Nations start.

After scoring an excellent try to put Wales in front, Louis Rees-Zammit then impresses with his defensive work, tackling James Lowe and forcing the Ireland wing into a knock-on.

Before then, Taulupe Faletau might have felt like he had been run over by a truck when he was bounced out of a tackle by CJ Stander.

Faletau looks fine to continue, somehow.
