The Raiders are all but resigned to the fact that star forward Corey Harawira-Naera will have to retire.
The Kiwi Test forward hasn't played since suffering a seizure on the field in Round 13 against South Sydney.
It was expected that the club would assess Harawira-Naera's future in the new year, but coach Ricky Stuart has told Wide World of Sports that officials are not optimistic.
