Springbok training has been suspended for Monday following a positive test in the squad.
The players have been placed in preventative isolation prior to further PCR testing and a review of the testing data by the Medical Advisory Group (MAG).
Lood de Jager returned a positive outcome in scheduled testing and, because of his close contact with a number of squad members, the entire group has gone into isolation.
An update will be issued following the review by the MAG and the further testing.
It is not the first time the Bok camp has had to contend with a Covid case after three positive Covid-19 tests were reported last month.
Sbu Nkosi, Vincent Koch and Herschel Jantjies were put into self-isolation as a precaution.
