Grant Gilchrist is determined to seize his 'massive opportunity' after being handed a debut against France on Saturday night.
The 22-year-old Edinburgh lock will make his bow for Scotland as they conclude their Six Nations campaign in Paris.
He is the latest player to receive their first start from interim head coach Scott Johnson, who also gave debuts to Duncan Weir, Rob Harley and Sean Maitland.
Gilchrist has welcomed the Australian's decision to put his faith in young players and intends to justify his selection with an impressive display.
"It's a massive opportunity for me, something I have dreamt of since I was a kid, to play for Scotland. I just can't wait to get on with Saturday night," he said.
"It's brilliant that Scott is willing to show faith in us young guys - but it is up to us now to deliver."
Gilchrist replaces the injured Richie Gray and insists he is relishing the challenge of deputising for the highly rated forward.
"Richie is a world-class player but I don't really feel any extra pressure because it's his place I have taken," he said.
"I do feel pressure to perform for my country and that wouldn't change, no matter who I was coming in for. It's a massive job and one I'm really looking forward to."
