Conor Murray is still struggling to come to terms with his shock inclusion in Ireland's World Cup squad.
Murray, 22, only broke into Munster's team this year and made his first Test appearance against France 10 days ago but he has edged out Tomas O'Leary for a place in the 30-man squad.
"I live with a few of the Munster lads and they were trying to shake me to get me excited," said Murray.
"I still hadn't really realised what had happened."
Murray has been the beneficiary of O'Leary's collapse in form.
O'Leary's poor display in Saturday's 26-22 defeat by France appeared to drop him from first choice in Declan Kidney's thinking to missing out altogether on the New Zealand trip behind Eoin Reddan, Isaac Boss and Murray.
Murray appeared just as surprised as the large media contingent at Monday's squad announcement in Kildare.
"Throughout pre-season I had an idea of where I was. I just didn't expect to get the call.
"It was bit of a surprise to make it at Tomas' expense but it's such a competitive squad, no one can take their place for granted.
"My first start was against the Dragons in March. I was just trying to have a good game. It was the biggest game I'd played at the time.
"I was kept for the next game and that gave me some confidence. I felt I could handle this level and kicked on from there.
"Everything's happened quicker than I expected."
