Greig Laidlaw lines up a shot at goal, but he has got his geometry a little askew.

"Scores have come from possessions and restarts pretty quickly.

"The scoring rate has been pretty high so Scotland will want a reply almost instantly here."

Bodies strewn across the pitch as a ruck disintegrates into chaos. Referee Wayne Barnes decides it was Scotladn who got the wrong side of the advantage line first. Nicolas Sanchez calls for the tee and wallops over a solid kick.

Stuart Hogg comes off his left foot and swats aside the flailing arms of an Argentine defender. He is the sort of runner who could beat his man in a phone box. Unfortunately for Scotland Mark Bennett makes a mess of his attempt to pick and go, spilling forward.

"Ireland have started well. The analysis before this game is that in the last 20 minutes, when games are won, the South Africa bench is stronger than Ireland's. We shall see."

Ireland win a penalty as Jack McGrath gets the upper hand on Jannie Du Plessis at a scrum and Jonathan Sexton kicks the hosts into the lead.

A superb stick-splitter from way out West from Greig Laidlaw pulls Scotland level.

"That was a very good reaction by Scotland to conceding an early try.

"Very simple play with numbers in the wider channels and it's a great example of what Richie Gray can do."

Scotland bounce back with an immediate response. Sean Maitland draws his man and Richie Gray is roaming outside him, showing a sniff of a pass to winger Manuel Montero who is only too pleased to buy the dummy. Gray shifts his angle inside and slides over.

"Scotland will want to get on top of this Argentine pack as much as they can when the ball gets loose.

"They just need to be patient in the 22 and maintain some composure."

Better from Scotland. Finn Russell is playing up on the back foot..

"That's not the start Vern Cotter would've wanted, but now Scotland have got to react to it."

Nicolas Sanchez adds another two points with a accurate boot from out by the touchline.

About as much atmosphere at Murrayfield as in deep space after that deflating start.

Sanj:, external So confused... do the Irish have two national anthems?

"From an Irish perspective, I'm very excited to see the new centre combination of Robbie Henshaw [who starts at 12] and Jared Payne. I think the players will switch around a bit as to who plays 13."

"A couple of great kicks from Scotland.

"Suddenly a big tackle goes in - there's a turn over and Ortega Desio runs the length of the field to score."

Ireland full-back Rob Kearney takes out South Africa counterpart Willie Le Roux in the air as he catches a hanging kick, but it is just a penalty to the visitors.

We're under way in Dublin and Bryan Habana is soon bundled into touch for the Boks.

Scotland looked like they were building nicely as Finn Russell put up a statospheric bomb and his team-mates chased hard. The hosts regained possession but Jonny Gray gives Greig Laidlaw a hospital pass, soft and loopy, and Manuel Montero flattens the scrum-half.

The ball spills loose and Javier Ortega Desio scoops up and scampers in from halfway, showing a good turn of pace.

The kick-off is safely gathered by the Scotland forwards and we are up and running.
