Ray Stone is out for four to six weeks after breaking his hand in the match against the Panthers.
The hard-hitting lock did the injury in the first half of the close loss to Penrith, but finished the match.
He did not require surgery, and his hand has been placed in a brace.
The earliest Stone could be available would be the match against the Roosters in round 24.
