South Africa lock Bakkies Botha has lost his appeal against a two-week ban.
The Blue Bulls forward was cited for a dangerous charge on British and Irish Lions prop Adam Jones during last Saturday's second Test in Pretoria.
It left Wales international Jones with a dislocated shoulder, and he has now flown home for further treatment.
Botha's appeal was heard via conference call this morning, and the decision to uphold his suspension means he misses Saturday's final Test at Johannesburg's Ellis Park.
The Springboks, who hold an unassailable 2-0 series lead, will also be without flanker Schalk Burger.
Burger was cited and banned for eight weeks after being found guilty of making contact with the eye area of Lions' wing Luke Fitzgerald.
