The 23 players in Wales’ matchday squad have 334 caps between them, while South Africa’s replacements alone have played a collective total of 431 international games.
In all, the Springboks’ matchday 23 have 951 caps between them.
South Africa are overwhelming favourites to inflict defeat on Wales, who have lost their past 11 Test matches.
Speculation continues about Warren Gatland’s future as Wales head coach in the wake of last weekend’s defeat 52-20 against Australia.
Gatland has won just six games from 23 Tests since returning for a second stint as head coach in December 2022. The 11-match losing run is a new record for Wales.
“Last week’s result hurts and we are just as disappointed by it as the fans,” said Gatland.
“Our focus now is on training and preparing well for our final game of this Autumn Nations Series.
“There were good elements that we can definitely build on going into Saturday but we have to improve our accuracy.
“We know what a quality side South Africa are and the physicality they bring. This week we need to show real courage and front up against the world champions.”
