A broken leg could see Warriors recruit and Kiwis utility back Gerard Beale miss up to eight weeks of next year's NRL campaign.
The 27-year-old Beale collapsed in New Zealand's 38-8 Rugby League World Cup pool win over Toa Samoa in late October and duly underwent surgery.
While he appeared to injure himself under no contact, coach David Kidwell later told reporters that Beale had hurt himself making an earlier tackle.
His recovery time has been projected at six months, ruling the ex-Shark out of the remainder of the World Cup and around eight weeks of NRL in 2018.
He is convalescing in Auckland, and has been in regular contact with Kidwell and the rest of his Kiwis teammates as they look to progress through Pool B.
They'll play Tonga for top spot in the pool on Saturday.
Dean Whare stepped in admirably for Beale in last week's 74-6 thumping of Scotland, while Peta Hiku is also capable of stepping into the breach.
As a result, Kidwell was rebuffed in his attempts last week to nominate a replacement for Beale. Rugby League World Cup guidelines allow for player replacements, but only if injuries leave a team short in a particular position.
"It's not possible - through the Rugby League World Cup rules, you have to wait until your stocks are depleted," Kidwell said this week.
"There's 24 committed guys in the jersey and Gerard's still part of this team, still feels like he belongs and, whenever he can, he'll be part of this."
Elsewhere, the Warriors confirmed Tongan centre Solomone Kata would have surgery on a broken foot sustained in his side's 32-18 Cup win over Samoa.
He would be ready for pre-season training in January.
