Springbok Sevens coach Neil Powell said the long-term welfare of the player was paramount.
“Hacjivah has a full season of rugby ahead of him next year and his recovery towards that is more important than our short-term goals for this weekend, so there is no sense in risking him,” said Powell.
Dayimani will be replaced by Impi Visser, who played in all 10 tournaments of the HSBC World Rugby Sevens Series last season. Powell will name his 12-man squad for the tournament on Thursday.
