Ospreys prop Jones had to have his shoulder put back in place after a charge from Springboks second row Bakkies Botha. The Springbok was cited after the game for the challenge and has been suspended for two weeks so will miss the final test as well.
Botha's charge led to Jones dislocating his right shoulder which was put back in place under anesthetic. He will see a specialist on his return to find the full extent of the damage.
Centres Jamie Roberts and Brian O'Driscoll also went to hospital, along with Tommy Bowe. Roberts damaged his right wrist, although X-Rays showed there is no fracture.
