The big one.

Ireland boss Andy Farrell has named his team for this weekend’s crucial Rugby World Cup clash with South Africa in Paris.

Bundee Aki is set to win his 50th Test cap for Ireland as he partners Garry Ringrose in midfield for the third consecutive match. Aki made his Ireland debut against South Africa in November 2017.

Hugo Keenan, Mack Hansen and James Lowe continue in the back three, with captain Jonathan Sexton and Jamison Gibson-Park named at out-half and scrum-half respectively.

Farrell has named an unchanged pack from last weekend’s defeat of Tonga in Nantes. Andrew Porter, Ronan Kelleher and Tadhg Furlong pack down in the front row, with Tadhg Beirne and James Ryan in the second row. Peter O’Mahony, Josh van der Flier and Caelan Doris complete the starting XV.

Dan Sheehan has returned to fitness to be named on the replacements bench alongside forwards David Kilcoyne, Finlay Bealham, Iain Henderson and Ryan Baird, while Conor Murray, Jack Crowley and Robbie Henshaw provide the backline reinforcements.
