Glasgow hooker Kevin Bryce has replaced Stuart McInally in Scotland's World Cup squad.
Bryce was given the surprise news on Monday afternoon after McInally failed to recover from a neck injury.
Bryce, who was also a late call-up to Scotland's provisional training squad, said: "It was quite a shock and it's not quite sunk in yet."
Bryce won his first call-up in Scotland's 2014 summer tour but did not feature off the bench after being called up ahead of their warm-up win over Italy in Turin last month.
The 27-year-old, who played in Glasgow's Guinness PRO12 win over Connacht on Friday, said: "I have been on the fringes and went away to Italy but I never thought I was going to get the phone call.
"I can get excited now. It's my first World Cup so I will see what comes my way."
Scotland head coach Vern Cotter felt Bryce's versatility made him the right replacement.
"Our hookers can play loose-forward and Kevin as an ex-loose-forward ticks the boxes, he can cover two positions," Cotter said. "He came with us to Canada last year and played loose-forward in a game and came with us to Italy as back-up. He knows the squad.
"He's a very good ball-carrier, he's an aggressive chap and works hard. We know he will give us everything he has got."
Like Bryce, Edinburgh's McInally only has two caps, with injury and illness delaying his Scotland debut until the victory in Turin.
"I'm really disappointed for him," Cotter said. "He has worked hard and to not be able to take part in this year's World Cup is very tough on him.
"He's a great rugby player, a good character. He's a leader and we hope he recovers as quickly as possible."
