nib Newcastle Knights forward Jermaine McEwen will miss the next two weeks after suffering a low-grade hamstring strain late last week.
Front-row forward Cody Hopwood will also be unavailable for this week's clash with the Sharks, after sustaining a low-grade calf strain.
Meanwhile, Knights winger James Schiller has undergone successful surgery on a neck injury and is expected to be sidelined for 4-6 weeks as he begins his rehabilitation.
The club will continue to monitor all players' rehabilitation and provide updates on their return to play as appropriate.
