Sam Prendergast starts at out-half as Garry Ringrose and Josh van der Flier are back at centre as Ireland face South Africa on Saturday.
"South Africa are the world champions and we know the challenge that awaits us this weekend” said Ireland head coach Andy Farrell.
“Whenever you face a top side you know that you have to be on top of your game and that you will be tested and we'll look to build on the momentum from last weekend and approach the game positively”.
"The players were galvanised by the support (last weekend) and it makes such a positive point of difference when you're at home”.
“There’s familiarity and respect between both teams and I know how excited the squad is to represent Ireland to the best of our ability for our last home game of 2025."
Captain Caelan Doris leads the side from the back row as Farrell's side welcome the Springboks to Dublin for the final Test of 2025.
