Jesse Kriel has not recovered sufficiently from a hamstring injury so will be replaced in the Springbok squad by Damian Willemse, the Stormers back who has been on loan with Saracens in England.
Kriel sustained a hamstring injury in the opening match of the tournament against New Zealand and although the condition has improved it was insufficient to put him in contention for either of the remaining two pool games.
Willemse, 21, will join the squad in Japan on Thursday. He won all of his five caps in 2018.
“Damian would have been more involved with us this year but for injury, but he is familiar with our systems and should have no problem slotting in,” said Rassie Erasmus, South Africa’s director of rugby.
“He has the ability to play in a number of positions in the back division, while other players can cover Jesse’s No 13 jersey. I feel for Jesse. He has been in the match-day 23 for almost every match since I took over and is a model professional. He was a key member of the squad.”
Willemse is the second replacement in the Springbok squad after prop Thomas du Toit had previously replaced Trevor Nyakane.
The Springboks face Italy on Friday in Shizuoka in a crucial Pool B clash.
