The Blues have lost another player to injury with All Black lock Anthony Boric returning home with a neck complaint.
Boric left South Africa along with wing Rene Ranger who has been suspended.
Coach Pat Lam says Boric has a disc problem and he's been told he could be out of action between 2 to 6 weeks.
The Blues take on the Stormers in Cape Town this weekend with lock Filo Paulo getting his first start.
David Raikuna replaces Ranger, while wider training squad member Ben Lam goes onto the bench as cover for Michael Hobbs and Isaia Toeava, who left South Africa last week.
