Ireland will have another roll of the dice as Wales fail to find their man in the line-out.

Wales infringe as they attempt to snatch back possession. Paddy Jackson pokes the penalty into the corner. Line-out Ireland. Five metres out.

Grandstand finish to follow.

It's been a lively old performance from the Scots, with the likes of Tim Visser relishing the chance to get his hands on the ball.

Can they really twist the knife in the second half?

Iain Henderson wins the line-out for Ireland, but Justin Tipuric is onto the ball like a limpet as the hosts try and get the rolling maul rumbling.

These two have been the best two players on the pitch.

Held up. Turnover and Ireland hopes getting very skinny.

Wales with the ball, and the clock and the scoreboard in their favour.

Finally Ireland get a chance to get their mitts on the pill.

Paddy Jackson kicks a penalty up into the Wales half for a line-out. 

His side need a converted try.

They have five minutes to find one.

Ireland are going out with a whimper as the rain starts to piddle down.

Paddy Jackson boots another aimless kick down the throats of the Wales back three. 

It is run back with interest and replacement Hallam Amos could have made the hosts really pay if George North had kept the ball in hand.

Leigh Halfpenny takes off the scrum-cap and slots to push Wales further clear.

Rhys Webb's afternoon is done. Off he comes to be replaced by Gareth Davies in the Wales scrum-half slot.

The massage men and women are going to have some overtime to work tonight.

Alun Wyn Jones has strained a leg, while Ireland centre Luke Fitzgerland has come off with a grimace.

Wales have been offensive in defence all afternoon, up fast, hard and accurate.

As Ireland run out of options, the red tide rushes up to charge down Paddy Jackson's ambitious pop at a drop-goal.

From the moment soon after the start they discovered they had dominance in the scrums, Scotland have not looked back.

They're moving the ball crisply and with the home pack on top, they will be relishing the second half - especially with Italy still down to 14 men.

Leigh Halfpenny loads the ball onto the tee, locks his sights on the sticks and drills over the top.

More machine than man at times. Wales lead once more.

Johnny Sexton off and Paddy Jackson is on. Sexton looks like he has had a bang on his elbow. He is resting up with the modern version of the bag of peas on the bench.

Eoin Reddan is going to get a run-out as well at scrum-half.

Keith Earls is taken off in a neck brace, but he acknowledges the crowd's applause with a hand in the air as he goes.

Hopefully that won't be World Cup wrecker.

Is it a hip injury? Or a groin twinge? 

I think Keith Earls is struggling with a head knock actually. The doctors are, quite rightly, taking their time. He is loaded onto a stretcher as the golf buggy rolls on to take him off.
