South Africa have been given a 48-hour deadline to decide whether they will compete in the Rugby Championship.
The Springboks are due to start the defence of their title against Argentina at Suncorp Stadium in Brisbane on November 7.
Rugby South Africa (RSA) last week said "several hurdles needed to be cleared" before the organisation can confirm that the world champions will feature in the four-nation competition.
Concerns have been raised over a lack of playing time for South Africa players due to the coronavirus pandemic.
Tournament organisers SANZAAR on Wednesday stated that a decision must be made within two days.
A SANZAAR statement said: "The SANZAAR member unions have agreed to provide South Africa Rugby with an additional 48 hours to finalise its internal stakeholder discussions.
"This will now delay the scheduled departure of the Springboks from South Africa to Australia.
"SANZAAR will provide an update on the resolution of these discussions and a timetable for the Springboks participation in the Rugby Championship when available in the coming days."
