The Springboks need to beat Argentina by a considerable margin in Durban on Saturday if they are to win the Rugby Championship title.
This follows New Zealand's 40-14 win over Australia in Auckland.
The bonus-point win put the All Blacks five points clear of the Springboks on the Rugby Championship standings, with a points difference of 67 (39 better than SA).
In order to win the title, the Springboks will not only have to score three tries more than Argentina to claim a winning bonus point, but they'll also have to beat Los Pumas by at least 39 points.
In case of teams finishing level, Sanzaar rules dictate that points difference head-to-head between them during the season will determine the winner.
A 39-point win for South Africa would therefore see them crowned champions because they boast a cumulative 49-45 score over New Zealand in their two matches (26-10 and 23-35). More wins cannot be a factor because both sides would be equal on that front too.
Saturday's clash at Kings Park kicks off at 17:05.
