The Wallabies have suffered a blow ahead of their Rugby Championship match against South Africa as Stephen Moore has been ruled out due to injury.

Moore was ruled out of the match and withdrawn from the Wallabies squad due to a lower grade strain in his right hamstring.

Moore's injury means that Tatafu Polota Nau moves up from the bench to the starting line up and his place on the bench is taken by Reds hooker Saia Fainga'a
