Stuart Hogg and Sean Maitland are both included in the squad as is former Warrior Richie Gray.
Sean told Sky Sports News: "I'm pretty speechless, I am over the moon, words can't describe what I'm feeling at the moment. The squad went live, I was watching it with the Glasgow boys in the changing room and that's when I found out.
"It's been a rollercoaster for me, coming over here to try and achieve new goals.
"Playing for Scotland was a very proud moment and in a Lions year it has worked out well for me, but the hard work begins now."
Sean is also the cousin of Australia fly-half Quade Cooper, and would relish the chance to lock horns if the Reds playmaker is included in the Wallaby squad.
He said: "We could talk about a rivalry that started at the age of five when he beat me in a long-distance race. He's had the wood over me in a few recent battles so hopefully we can get one over him."
Stuart Hogg could not bear to watch the announcement with the rest of his Glasgow teammates. “I was out kicking with Mossy [Chris Paterson],” he explained in the Scotsman. “I ran back in to get my kicking tee and picked up my phone at the same time, and gave it to him and started kicking. After I’d kicked a few, I asked him for the phone and went up the other end and started watching it on the Sky app.
“Initially, I wasn’t going to watch it, then I was, then I wasn’t, and then I did. As soon as I saw it on the screen I screamed like a little girl. Mossy heard me from the other end of the pitch. It’s a feeling that I’ve never really experienced before. I have no idea how to describe it. When your name comes up it’s just a big relief. Jim [Renwick] just sent me a message with two words: ‘ya beauty’. So I think he’s happy.”
