Scotland skipper Alastair Kellock has admitted he was "gutted" to find out he had been axed for the crunch tie with Argentina.
Kellock led Scotland to a 2-0 series win over the Pumas in 2010, but he has lost his place in the team to Richie Gray and Jim Hamilton - with Nathan Hines preferred as cover on the bench.
And Kellock admitted his omission from the side to face Pumas was tough to hear.
Writing in The Scotsman, Kellock said: "Andy Robinson took me aside on Monday and told me I was out.
"I knew he wanted to speak to me and hoped it would be about plans for Argentina, but he didn't beat about the bush.
"He said 'I'm not going to involve you this week', and in that moment the ground could have opened up.
"I want to say I was gutted, but that doesn't do justice to the feelings you experience at that moment."
