Cape Town - The Sunwolves have lost the services of lock Sam Wykes and fullback Yasutaka Sasakura ahead of Saturday's clash with the Stormers in Cape Town.
Both players sustained injuries during the Tokyo-based outfit's 94-7 defeat to the Lions in Johannesburg at the weekend.
The Sunwolves have called up lock Yuya Odo as a replacement for Wykes ahead of the clash at Newlands.
Despite representing Japan on three occasions, Odo will make his Super Rugby debut if he takes to the field this weekend.
