The All Blacks don't like losing. And if we didn't already know that we do know now. The visitors have been very physical, some might say over-physical, with a few dubious shoulder charges. 

Ireland go backwards from the scrum, but win another penalty inside the All Blacks 22 when they are caught offside. Paddy Jackson asks for the kicking tee...

Come on then Ireland, make this numerical advantage count. CJ Stander is shoving men out of the way like an angry nightclub bouncer. Ireland go left, then go right... into the 13th phase... Outstanding stuff. 

Irish scrum in front of the posts...

The second half is up and running at Murrayfield.

Scotland play Georgia next week and the Lelos have just enjoyed a fantastic 20-16 win over Samoa.

Is the order of world rugby changing? Maybe not, but there was also a brilliant win for Italy against South Africa earlier today. The hosts beat the Springboks 20-18.

This is everything we expected. The commitment has been total. 

I really feel for Sexton. He knew immediately he was injured and you could see from his reaction how disappointed he is.

Another blow for Ireland. Johnny Sexton's troublesome hamstring appears to have pinged again. The influential fly-half can't carry on, Paddy Jackson is summoned from the bench.

The All Blacks line is proving harder to break down than a coal face. Ireland are chipping away though, forcing Aaron Smith into kicking the ball away at the breakdown. Referee Jaco Peyper loses his tether, saying Smith has caused one too many infringements. Cool off in the sin bin young man.

The problem has been, for Ferguson in particular, his legs are a long way back so when there is pressure put down on him he is not able to sustain it.

Argentina are putting a huge level of weight and pressure on. If Ferguson's right leg is up a bit further he will be able to sustain some of the pressure. 

It is the only thing that is keeping Argentina in the game.

Scotland have had intent to play like they did last week but the circumstances are not allowing it.

You have got to find a way to get your game into this match.

Both teams have made so many mistakes and neither team has been able to grasp it.

Ben Jones-Groves: Embarrassing decision by the TMO in my opinion. He COULD NOT see a CLEAR grounding. 

Andrew Priestly:Given the fact that Sexton tackled Barrett around the neck, it would have been a penalty try anyway

I am not sure the ball did touch the ground.

But the All Blacks won't be stopped this time. Or have they? Beauden Barrett uses that lightning pace to full effect after spotting a gap, but has he grounded the ball properly. Over to the TMO...

New Zealand ease the pressure with a deep kick, Rob Kearney responds with his right peg. He doesn't find touch though - and it almost proves fatal. Beauden Barrett carries from deep, breaks the line and flicks inside to Israel Dagg. Andrew Trimble cuts out the pass but can't hold. Unlucky sir. All Blacks scrum.

It's a very close-fought battle at Murrayfield. A smattering of attacking chances and if anyone looked more like grabbing a try it was Argentina, but that Scottish defence has stood firm.

Greig Laidlaw leads Nicolas Sanchez 2-1 on the penalty count and that's enough to see Scotland lead at the break.

Oh dear, Robbie Henshaw can't carry on. He is taken off on a stretcher, on trots Garry Ringrose. Johnny Sexton drills the penalty into touch, time for the big men to bust up some All Blacks.

Scotland will look for more detail and accuracy in the second half so they can launch their game and put pressure on Argentina.
