He was part of Gloucester's squad in the JP Morgan Asset Management Sevens tournament recently but the Scarlets match was his first involvement with the first XV.
Talking to the media after the game, Ryan was modest about his display and quick to credit some of the other young players in the Gloucester set up for helping to put him at ease.
"It was a tough game but we've trained hard for a few weeks now so it was just a question of putting it all into a game but I think it went well to be honest."
"I was originally named on the bench but I was lucky enough to make my first start and I was happy about that."
"It was good to have the likes of Jonny May and Charlie Sharples. They've both played a fair bit of Premiership but had been through what I was experiencing against the Scarlets."
"They've come through the system, Freddie Burns as well, which really helps you to deal with days like that."
Quizzed about his aspirations for the coming season, the Exeter born 18 year old isn't looking too far head and his feet are obviously firmly on the ground.
"I'm going to keep training and pushing hard to try and stay involved then it'll be down to the coaches. I'm hoping to make England 20s this year which would be good for myself and for Gloucester."
"I missed the (England U18) tour of South Africa due to injury. I had a bad hip flexor but I was involved throughout the season and it went well."
"England 18s like to play a really quick game and encourage you to play what you see which means your fitness has to be good and it helps you to develop as a player. I think the 20s will be similar if I make it in."
