The Warriors have been dealt a double injury blow with Tohu Harris and Bunty Afoa both ruled out for six weeks.
Both players were forced off the field in the side's 18-15 loss to the Sharks on Friday.
The club reports on their website that both forwards will miss at least six weeks.
Harris limped off in the final minute of the loss and scans have revealed a meniscus tear in his left knee. Afoa dislocated his left elbow and faces a similar length on the sidelines.
