The Crusaders will have to do without Crotty and Scott Barrett as both picked up injuries in their semi-final match last weekend.
Both players have also sustain bony injuries to their hands and will therefore not be available for the final against the Jaguares.
Crotty fractured his thumb and underwent surgery to stabilize it. He will be out of action for up to 8 weeks.
Barrett fractured the 2nd metacarpal, at the base of his index finger. He will only be able to return in 5 to 6 weeks.
The finals will be at 09:30 Saturday and it will be live on SuperSport 1
