Andy Farrell takes charge of Ireland for the first time as they begin their Six Nations campaign later today.
They host Scotland at the Aviva Stadium from a quarter-to-five, with Leinster's Caelan Doris in line to make his debut at number eight.
CJ Stander starts at blindside flanker - and he's looking forward to the challenge; "Place that I'm familiar with in this squad, it's really a number change and I think my job there is to make sure I get into space a little bit and work with the boys around me and gave them an easier job".
