It is all Ireland at the moment, Scotland have to do something to stop this flow of Irish attack.

They are dominating with Conor Murray and his box kicking, Scotland have to do something to keep them out.

11 of Ireland's starting 15 have made over 10 metres. Scotland have just 5 in double figures.

Scotland look like they are running out of steam here.

Paddy Jackson pokes a shrewd grubber into the corner and Keith Earls drags a weary Stuart Hogg into touch.

Ireland line-out, five metres out from the Scotland line.

It is unbelievable. Conor Murray's box kick actually hit one of the wires above the stadium and that held it up in the air to Scotland's advantage.

I think the camerman who controls it panicked, because the camera came flying towards us for a moment.

There are a lot of tired bodies and fatigued minds out there.

Stuart Hogg survives landing smack-flat on his back as he chases a high kick and goes over the back of his team-mate Ryan Wilson.

Vern Cotter freshens things up by bringing on Tim Swinson for Josh Strauss.

Ireland have hooked Sean O'Brien. Josh van der Flier is on in his place.

A superb try from Ireland. They are winning the muscle - they are winning the battles up front. Good finish - they did well to finish that. 

We spoke about the quality of Scotland's tackling in the first half, that has fallen off this half - they have lost that 'bite' we spoke about.

Paddy Jackson hit that space between the second and third defender with a great line, backing his quality. That is what you want from your 10.

Ireland have more attacking metres in the first 21 minutes of the second half than they did in the entire first half. Scotland have made 43 second half metres. Scotland 208 metres, Ireland 368 overall.

Henry Vice: As good as Hogg has been going forward, Kearney just made his defence look very weak there. Gatland wouldnt have missed that  

Daniel Whitehead: Will bonus point psychology have an impact in the last 20?!  

Thomas Harrington: Glad that Cian is finally on he will make a difference. Missing 2 key players and a lethargic first half but we should just sneak this game now by a few points.  

Mark Bennett - the Glasgow centre - is on in place of Huw Jones for Scotland.

It's amazing defence again from Sean Maitland, but this is a different Test match now - all the pressure is coming from Ireland. It's backs to the wall for Scotland. 

Huw Jones is coming off and it is a change that doesn't surprise me, match fitness at this intensity is difficult and Mark Bennett has been in great form.

Rob Kearney was in touch by a fair margin. Scotland survive once more as Finn Russell hoofs the ball back to the home 22m.

There are still more than 20 minutes to go though and surely Scotland cannot hold out under such pressure for all of that.

Ireland flanker Sean O'Brien is the most productive attacking forward in the game with 38 metres from 12 carries.

Keith Earls dives over, but Rob Kearney might have been forced into touch just before by Sean Maitland's last-ditch heroics.

When you go for those lows chips you are always running the lottery of it ricocheting of somebody’s legs.

Scotland survive once again!

Relieved cheers all around Murrayfield as Sean Maitland nips in to steal what would have been a scoring pass from Jamie Heaslip to Robbie Henshaw.

They were at sixes and sevens after Finn Russell's grubber was charged down in midfield by Conor Murray.

Cian Healy - a battleship of a prop - is on in place of Jack McGrath for Ireland.
