Injuries have rocked the Bulls while Luke Watson’s throat injury has forced him out of the Kings historic Super Rugby tour to New Zealand and Australia.
The Bulls management confirmed winger Akona Ndungane, scrumhalf Francois Hougaard and centre Wynand Olivier will return to South Africa because of injury. All three are Boks.
The replacements are Francois Venter, Ruan Snyman and Bjorn Basson.
The Bulls beat the Blues in their tour opener but took a 41-19 pasting against the Crusaders in Christchurch.
Watson, whose Kings face the Crusaders this weekend, has not recovered from the larynx injury suffered in the opening game against the Force.
