The Scotland U20 centre impressed on his Glasgow debut and received praise from Glasgow Head Coach Franco Smith.
"I thought Kerr was good," said Smith in The Scotsman. "He found his feet. He received some hard tackles from experienced campaigners. The two centres, their combined age is about four times his. So he did well to manage that and to stay in the game.
"I thought the way that the rest of the team helped him to adapt was really good. He's definitely made his mark and he now understands what it takes."
Kerr's father, Stuart Yule, is the Scotland's strength and conditioning coach, and his son looks physically equipped to deal with the demands of the URC.
Glasgow's skipper on Friday, Stafford McDowall, has watched Yule's progress over the last few seasons.
"I know his dad through doing the national team stuff and have followed him through the U20s," said McDowall. "He's obviously got quite a lot about him to come out as the 20s' most capped player ever. We've all watched him improve through training in the last two or three years and improve with the 20s and turn into a key player for them and eventually he'll turn into a key player for us and it was good to see him get his first game.
"He's some unit. He's definitely got the strength from his dad, I think. I see him in the gym and he's lifting more than most of us. He's a great guy, he's got a real level head and you can see he was really calm when it got tough out there."
