Wales have been camped on the Ireland line and the home side have been warned for continually infringing with back-rower CJ Stander the main culprit.

Wales captain Alun Wyn Jones opted for an attacking scrum with a delay as both sides struggled for dominance at the set-piece.

And in what you sense could be a key moment Wales are then penalised for collapsing the scrum and Ireland clear the danger.

CJ Stander better be careful.

He's just given away three penalties at the ruck.

You need to have control of the ball in the act of scoring a try.

He doesn't have it. There's no debate.

Hadleigh Parkes with the now traditional one-handed knock-on at the Aviva Stadium.

A disappointing end to a brilliant passage of play from Wales, who know fine well there's a lot more rugby to be played before this game is decided.

Wales have shown more adventure in the last couple of minutes with an offload game in evidence.

And they seemed to have gained the reward with a try from centre Hadleigh Parkes but it was ruled out by the television match official after it was adjudged the Wales back lost control in the grounding.

Wales have really increased the pace of their game.

It's a bit frantic but that's what they've got to do to move around this Irish defence.

Wales have been forced into a rearguard position and they just haven't been able to break the territorial stranglehold that Ireland have over them.

Wales have made a couple of changes to try and get back into this game.

Scrum-half Gareth Davies and back-rower Ross Moriarty replace Tomos Williams and Aaron Wainwright.

Robbie Henshaw has put in a humongous effort today, stepping up as a carrier and distributor.

Really putting himself out there to start if everyone is fit.

Robbie Henshaw and Dan Biggar have gone off the field for head injury assessments after the earlier collision.

Munster back Keith Earls and Cardiff Blues fly-half Jarrod Evans have come onto the field.

Ireland weren't aggressive and dominant in the collisions last week but they've really learned their lesson.

Forcing mistakes and knock-ons from Wales.

An eventful start to the second-half as Wales fumble the ball on a couple of occasions with Dan Biggar and Nick Tompkins spilling possession.

Biggar also hurt Robbie Henshaw after running into the Ireland centre. Henshaw continues after receiving lengthy treatment.

Let's focus on the here and now, the storm may never come.

But let's hope there's a storm from a Welsh perspective in the next 10 minutes, that's what is needed.

This time it is Wales fly-half Dan Biggar who kicks off to start the second-half as the visitors trail by five points.

Ireland, who kept Wales waiting on the field before the second-half started, will be aiming to keep up the dominance they achieved in the opening 40 minutes. No changes to either side at the break.

Wales might have to rethink their defensive strategy in the second-half because they are so narrow and Ireland are exploiting the outside channels.

Wales will hope to benefit from the wind in the second-half but it is swirling around the Aviva Stadium.
