The controversy over the eligibility of Zimbabwe-born Tendai "Beast" Mtawarira to play for the Springbok rugby side has stalled his international career.
An instruction from the Department of Sport and Recreation to the South African Rugby Union means Mtawarira - or any other non-South African passport holder - will not be able to represent the national side.
Though resident and employed by the Sharks, Mtawairira - who has gained 22 Test caps since his debut in 2008 - still holds Zimbabwean citizenship.
"We have had extensive and robust conversations with government on this issue," said Oregan Hoskins, president of Saru. "But we respect the authority of the Ministry and have instructed our selectors in that regard."
Hoskins added that Mtawarira wished to become a South African citizens as soon as possible and Saru had been assisting him in fulfilling the necessary criteria.
