Elliott Whitehead will miss one more week of action with a shoulder injury sustained in the Raiders round 16 match against the Titans.
Whitehead was hopeful of being able to play against the Sharks this weekend, but medical staff have decided to give him a further week to fully recover.
Dunamis Lui injured his calf in last week's win over Manly and will miss 1-2 weeks.
