Is this a sign of things to come?
South Africa's rugby sevens team could miss the Olympics after being forced into quarantine following a positive Covid test from a passenger they were sat near to, on a flight to Tokyo.
According to reports, 14 South Africa players and four staff members sat near the traveller.
The group tested negative upon arrival, but will move into a quarantine hotel.
That period in isolation ahead of the Olympics could last for as long as 14 days. The sevens competition due to start on July 26 they face a race against time.
