Injured first five eighth Peter Grant and number eight Ryan Kankowski have withdrawn from the Springbok squad for the Test against Argentina and the Tri-Nations series.
Grant is to have surgery to his right shoulder this week and is expected to be out for six to 12 weeks, effectively ruling him out of any further participation.
Kankowski also has a shoulder injury. He won't need surgery but is expected to recover in two to three weeks.
The Springboks face Argentina in Johannesburg on August 9th before continuing their quest for the Tri-Nations trophy against New Zealand in Cape Town a week later.
With Butch James expected to continue at No.10, Francois Steyn will likely provide cover at that position in Grant's absence, while Joe van Niekerk and Pierre Spies are established number eights.
