The Glasgow Warriors lock was widely expected to return to the line-up for the showdown with the Pumas but has once again been overlooked from the 22.

However despite the raised eyebrows at his decision Robinson insists the bigger picture of victory left him with little choice.

“This is phase two of our operation in this World Cup and we've got two games to win,” said Robinson. “We looked at picking a team to beat Argentina. That was the sole focus.

“When it comes to selections, any player that's been left out I found tough to do because every one of the players has put their hand up and for every single one of the players I could make a justification of why they should play for Scotland in this game.

“To be fair to Al, as always, he's taken it very well. He's an outstanding character.”

Robinson has made five changes to the side that beat Georgia with Chris Paterson replacing Rory Lamont at full-back while Dan Parks makes way at fly-half for Ruaridh Jackson.

John Barclay replaces Ross Rennie at open-side flanker while with Euan Murray not available to play on Sundays due to his religious beliefs, Geoff Cross comes in at tight-head prop.

Jim Hamilton is the man who replaces Kellock again while Richie Gray has taken Nathan Hines’ place in the second-row.
