The Ireland coaching team have named the Ireland match day squad to play Argentina on Sunday afternoon in their final game of the Autumn Nations Series.
James Ryan assumes the captaincy in the absence of Johnny Sexton and is partnered in second row by Iain Henderson.
The front row of Andrew Porter, Ronan Kelleher and Tadgh Furlong is retained as is the backrow of Caelan Doris, Josh van der Flier and Jack Conan.
A new half-back pairing of Conor Murray and Joey Carbery is introduced and Robbie Henshaw makes his season debut at inside centre, partnering Garry Ringrose in the midfield.
Hugo Keenan gets another opportunity to impress in the No.15 jersey with James Lowe starting his third consecutive game for Ireland. Robert Baloucoune, who made his Ireland debut against the USA in July scoring a scintillating try, gets his second start.
Dan Sheehan, who won his first cap against Japan earlier this month, and Tom O’Toole, who was capped against USA in July, are named as front row cover alongside Cian Healy. Tadhg Beirne, Peter O’Mahony, Craig Casey, Harry Byrne and Keith Earls complete the 23.
