Springboks coach Jacques Nienaber reverted to the starting 15 which beat Scotland in their opening game, only without hooker Malcolm Marx, who was ruled out of the tournament with a knee injury. Bongi Mbonambi comes into the starting team for Marx.
How quarter-final match-ups are looking
Lock Eben Etzebeth was selected to start after sustaining a shoulder injury and going off in the first half against Scotland. Captain Siya Kolisi, Pieter-Steph du Toit and Jasper Wiese are the loose forward combination.
Faf de Klerk is back at halfback to link up with first five-eighth Manie Libbok, and wings Cheslin Kolbe and Kurt-Lee Arendse are recalled.
On the bench, halfback Cobus Reinach, who can also play wing, is the only backline player among the reserves, with the Springboks naming three reserve front-row forwards, two reserve locks and two reserve loose forwards. Among them is Deon Fourie, the 36-year-old flanker who has been switched to reserve hooker after Marx’s tournament-ending injury.
While the 7-1 split worked against New Zealand, setting the Boks up for a record 35-7 win over their archrival, it also poses a major risk if one or more backline players get injured.
Ireland is rugby’s form team and on a run of 15 straight wins since July last year.
“We know it’s going to be a grind of a match and we know we need to pitch up physically and mentally. We also need to start with intensity and stay focused until the final whistle,” Nienaber said. “This is a massive game for both sides with an eye to progressing out of our pool, so we need to be extremely accurate in all areas of our game.”
