A day after the Warriors trumpeted the fact they would be able to play their top four props for the first time since June last year, Jacob Lillyman is a big doubt for Saturday's visit to Canberra.
Lillyman missed last weekend's 24-22 defeat to Souths with an ankle injury and didn't come through training today.
The Warriors have been a little down on grunt up front this season and were looking forward to fielding Lillyman, Sam Rapira, Ben Matulino and Russell Packer against the Raiders. Sebastine Ikahihifo, who is normally a second-rower, will come into the 17-man playing squad.
Back-rower Elijah Taylor is also a major doubt with a rib injury but centre Dane Nielsen returns after missing the Souths game with a rib cartilage injury.
Nielsen's recovery means coach Matt Elliott has a difficult decision to make. He said Manu Vatuvei would occupy one wing berth meaning either Bill Tupou or Ngani Laumape would miss out despite the fact the pair have been two of the best for the Warriors recently.
"Manu will be playing so it's down to Ngani or Bill,'' Elliott said. "Their contributions over the last two weeks is making this a tough call. I haven't made it yet. I need to think about that one.''
Warriors side to play Canberra at Canberra Stadium on Saturday: Kevin Locke, Bill Tupou/Ngani Laumape, Dane Nielsen, Konrad Hurrell, Manu Vatuvei, Thomas Leuluai, Shaun Johnson, Sam Rapira, Nathan Friend, Russell Packer, Feleti Mateo, Simon Mannering (c), Todd Lowrie. Interchange: Ben Matulino, Pita Godinet, Ben Henry, Sebastine Ikahihifo.
