Rob Kearney.
Rob Kearney will start full-back for Ireland in Saturday's final November series encounter.
Joe Schmidt's men will face Argentina in a repeat of their 2015 World Cup quarter-final with Kearney set to win his 78th cap.
Ireland are looking to make it three wins from three having prevailed against South Africa and Fiji in their other outings in the Guinness Series.
There is no place for his younger sibling, Dave, in the 23-man squad.
