Russell, who turned out for Scotland Under-18s last year, impressed County head coach Graeme Young so much in his few games in the RBS Premiership that he handed him the No.13 jersey in Ireland last Saturday.
However, the evening did not start well for Russell, the 18-year-old taking a knock to his nose after just five minutes. "It was quite a hit I took to my nose and there was a lot of blood, but the physio did a great job to patch me up and I was back on a few minutes later," he explained.
"The experienced players told me to expect the match to be that bit more physical and quicker than what I was used to and it certainly was. I loved it and, although we lost, I think myself and all the other young guys learned a lot. Now, it would be great to be involved this weekend when Plymouth Albion come to Bridgehaugh."
Russell is studying chemical engineering at Strathclyde University while living with older brother Finn, the Glasgow Warriors and Ayr stand-off. The duo often talk about rugby and use each other as sounding boards.
Russell, part of the County Under-18s who won their own championship last term, added: "The club have always been keen to get young players integrated into the first-team squad. We are all learning together and there is a great buzz, while the coaching team and the experienced players talk to us all the time and don't let us get too excited but stay focused on the game in hand."
