The duo are also paired in the Heineken Cup Pool stages and Ryan is hopeful that his side can continue the Scottish men’s miserable winless record in the RDS.
With Leinster minus many front-line stars, Ryan acknowledges there is a greater onus on him to lead by example.
“I suppose I find myself one of the more experienced players in the squad in recent times, but I prefer to lead with actions rather than words,” he said.”
Luke Fitzgerald takes his place at inside centre alongside Eoin O’Malley for tonight’s match, while Fionn Carr and Ian Madigan continue in a backline which also includes Isa Nacewa and Cillian Willis. In the pack, Leo Auva’a makes his first start for the province at number eight after appearing twice off the bench so far this season and he joins Ryan and Ruddock in the back-row.
