Second-rower Richie Gray insists Scotland can bounce back from their hefty defeat against New Zealand to put in an improved display against world champions South Africa on Saturday.
The All Blacks ran in seven tries against Andy Robinson's men as they started their autumn campaign at Murrayfield with a resounding 49-3 loss.
Gray made his first international start after three replacement appearances on Saturday, and admitted that the hosts let themselves down with their display.
Robinson will name his team to face the Springboks on Tuesday, and Gray says they will come out fighting after such a disappointing performance.
"We let ourselves down and the nation down," said Gray. "However, this is the positive about the autumn Tests, we've got another game to bounce back and get ourselves back on track."
The 21-year-old was among seven Scotland players struggling with injuries after picking up a dead leg.
Gray will be going up against the formidable Springboks second row combination of Bakkies Botha and Victor Matfield if he wins selection for next week's Test.
"The challenges just get bigger and bigger, but that's international rugby," added Gray.
"We'll build this week and we'll rectify the areas that went wrong. We'll remain positive and on the Saturday we'll have done everything to go out and put on a performance."
Gray is unsure whether he has done enough to retain his starting spot, with no Scotland player satisfied with their display in a comprehensive defeat.
"I was happy with some things, disappointed with others," added Gray. "I was happy with some of my set-piece work, a couple of good spells in attack.
"I got to grips with the games, but I'll need to improve a lot. The physicality and the pace of the game is something I'll need to improve and adapt to."
Scotland captain Mike Blair went off with a head injury before half-time on Saturday, while the game ended prematurely when centre Max Evans was taken off on a stretcher.
Evans suffered a 'stinger' shoulder injury but was able to attend the post-match function, while Blair rested at home.
Flanker John Barclay (ankle), Rory Lamont (tight thigh), Hugo Southwell (tight hamstring) and Alasdair Dickinson (shoulder) also required treatment.
