Pat Lambie will miss the series decider against Ireland in Port Elizabeth on Saturday as a result of the concussion he suffered in Cape Town eight days ago.
The Bok flyhalf was sent home last Sunday for a week-long mandatory rest according to the World Rugby Return to Play Protocol, ruling him out of the second Test at Ellis Park.
'Pat is still experiencing symptoms of concussion and because of that we cannot start the Return to Play Protocol. As a result of that he will unfortunately not be available for selection,' explained Springbok team doctor Konrad von Hagen.
That means Morné Steyn is likely to once again warm the bench for the Boks on Saturday, with Elton Jantjies retaining the No 10 jersey.
Meanwhile, three players who suffered injuries in Johannesburg were assessed with the rest of the players before the squad’s departure to Port Elizabeth in the early afternoon.
The two No 8s, Duane Vermeulen and Warren Whiteley, sustained elbow and shoulder injuries respectively, while prop Trevor Nyakane received a knock on the ankle.
'Duane, Trevor and Warren will undergo further scans on Monday in order to determine the extent of their injuries,' said Von Hagen.
Lock Lood de Jager, who sat out the Ellis Park match because of a calf strain, is undergoing physiotherapy and a decision on his availability will be made later in the week.
The Boks will have an open training session at 15:00 on Monday at the Zwide Rugby Club.
