Luke Metcalf has rejoined the injury roster alongside co-captain Mitchell Barnett at the NZ Warriors.
Both players were in rehab together for several months following their ACL surgeries.
In just his second game back, Barnett fractured his right thumb in a match against the Wests Tigers and underwent surgery last week.
The timeline for his return remains uncertain.
Metcalf sustained a hamstring injury in the 75th minute during last Sunday's defeat to Cronulla Sutherland.
There is currently no set date for his comeback.
Meanwhile, second rower Kurt Capewell, who has a calf issue, was expected to return this week but is still sidelined.
