The Blitzboks were stunned by Argentina on Tuesday, losing their quarter-final at the Tokyo Olympics 19-14 to see their chances of a medal disappear.
It is an incredibly disappointing result for Team South Africa, who were banking on the sevens side for a medal after they won bronze at Rio in 2016.
The South African task should have been made significantly easier by the fact the Argentina played the majority of the match with just six players after Gaston Revol was red-carded in just the third minute.
Instead, the South Americans were galvanised by that moment, and they ran in two tries in the first-half to take a 14-7 lead into the break after Selvyn Davids had scored first for South Africa.
When the underdogs scored their third try, South Africa were19-7 down and buried against all odds.
The Blitzboks were awarded a penalty try in the final minute of play, but it was too little too late.
Argentina - down to five men after a late yellow card - secured the kick-off as the hooter sounded and then cleared the ball into touch.
As the final whistle sounded, the South Africans fell to the turf in disbelief as their campaign came to an abrupt and unexpected end.
It will go down as one of the great Olympic Sevens upsets.
