WEATHER
There are light rain showers forecast for Dublin for early evening on Saturday. Temperatures expected to be around 7C.
Ireland face South Africa for the 31st time on Saturday evening with the hosts have 10 wins to their name in the fixture.
The Springboks have won 19 but they haven't tasted victory in Dublin since 2012, while there's been one draw, an 8-8 stalemate in 1970.
While the South Africans have almost double the wins, the tale of the tape reveals a close rivalry in recent years.
Ireland have won nine of the last 14 and four of the last five, most notably the Rugby World Cup pool clash in Paris in 2023.
South Africa, six-point favourites, are ranked one in the world, while Ireland dropped to fourth despite beating Australia last weekend – England's win over New Zealand worth more points in the World Rugby criteria.
Ireland could actually move to second in the rankings if they win by 15 points or more.
Andy Farrell’s side have a formidable home record with 25 victories from their last 27, while the visitors are on a nine-match winning run in Europe.
In team news, Farrell has recalled Garry Ringrose and Josh van der Flier, who missed the 46-19 win over the Wallabies through injury, while Bundee Aki comes in for Stuart McCloskey.
Andrew Porter starts at loosehead having come off the bench last weekend.
Caelan Doris moves to 8 from openside wingforward.

Having rested many of his frontliners in the 32-19 success over Italy last weekend, in which they played for most of the game with 14 players after Franco Mostert’s since-rescinded red card, Rassie Erasmus makes just two changes, Canan Moodie and Ruan Nortje, to the side that lined up against France two weeks ago.
That was a clash they also had to navigate with 14 after the dismissal of Lood de Jager, who yesterday had an appeal dismissed.
Boan Venter, Siya Kolisi, Damian Willemse and Canan Moodie remain from the win in Turin.
Leinster’s RG Snyman is on the bench and will win his 50th international cap, while even though Mostert was not considered, there is no place in the squad for Munster’s Jean Kleyn.

WHAT THEY SAID:
Andy Farrell (Ireland head coach): "We'll learn no matter what [the result], we'll learn but we're trying to prove to ourselves the whole time that we're taking steps forward.
"And this will be the litmus test for where we are, certainly, that's going to concentrate the mind in the next couple of months leading up to the Six Nations."
Rassie Erasmus (South Africa head coach): "It is a massive game. There has been good history between us and banter between the fans and the pundits.
"If we had lost to France and to New Zealand twice then what would the nature of this game be? We would be in survival mode. It is nicely pitched now."
