Van Staden has been drafted in as cover for Siya Kolisi and will remain in camp until there is absolute clarity about whether Kolisi will be able to take part in the initial stages of the Castle Lager Rugby Championship. Kolisi injured his knee in the Vodacom Super Rugby competition and is continuing with his rehabilitation in camp.

The Springboks will kick off their shortened Castle Lager Rugby Championship campaign on Saturday, 20 July, against the Wallabies in Johannesburg, which will be followed a week later by the keenly awaited rematch with New Zealand in Wellington - the scene of last year’s epic away win against the All Blacks.

The Boks will conclude their official campaign against Argentina two weeks later, on Saturday, 10 August, in Salta, while the same two teams are set to meet again a week later in Pretoria in a once-off Test before the Boks report for Rugby World Cup training duty.

The updated Springbok training group in Pretoria is:
