Ireland head coach Joe Schmidt will announce his team to face Argentina later this evening.
All eyes will be on who will be chosen to fill the outside centre position, with Darren Cave being tipped to be offered the first chance to stake a claim to becoming Brian O'Driscoll's replacement.
Ulster's Robbie Diack could be in contention to win his first cap for Ireland, while Connacht's Rodney Ah You is also likely to make his Test debut at some point during Saturday's clash with the Pumas.
