Members of the Blitzboks will be tested for the coronavirus after it was feared that they might have been exposed while at the Los Angeles and Vancouver Sevens tournaments.
The decision to test members of the team was as a result of the fact that two members of the Australian Sevens team had tested positive for the virus.
South Africa won the Los Angeles round of the Sevens World Series and finished fourth in Canada.
Rugby, like all sport around the globe has been severely hit by the pandemic.
