Ireland take on South Africa in first of two Tests in Pretora (16:00 BST)
Andy Farrell's side have only won once on South African soil - in June 2016 - and have never won a series.
This will be Farrell's last series before taking a year sabbatical to lead the British and Irish Lions in Australia in 2025.
Farrell hands a debut to Leinster full-back Jamie Osbourne with Munster's Craig Casey preferred to Conor Murray at scrum-half.
South Africa name 12 starters from the World Cup final win over New Zealand with scrum-half Faf de Klerk passed fit after an injury doubt.
The double world champions are the number one ranked side in world rugby with Ireland currently ranked second.

A massive carry from Siya Kolisi and Hensahw felt the full force of that. Thankfully no impact on his head or neck but that's a marker set from the Springbok captain.
Handre Pollard
Never in doubt. South Africa's lead is back up to seven.

Henshaw is back to his feet. That power from Kolisi was something else.
The Boks will have the put in at the scrum.

Siya Kolisi has absolutely flattened Robbie Henshaw. Like I mean completely steam rolled over the top of him.
Luke Pearce does the sensible thing and stops play so the medics can give Henshaw a quick check over.
