In-form wing Mack Hansen will make his Ireland debut in Saturday's Six Nations opener against defending champions Wales in Dublin.
The Australia-born 23-year-old, whose mother is Irish, has been selected on the left flank in place of the injured James Lowe following a string of standout displays for Connacht.
Hansen used to play Super Rugby for the Brumbies and represented the Wallabies at under-20s level, but is named by Ireland after his scintillating form for his province.
