The Warriors are in a race against time to see if captain Roger Tuivasa-Sheck can overcome an ankle injury for Saturday's NRL playoff against the Panthers in Sydney.
Tuivasa-Sheck picked up the injury late in the Warriors' 20-16 win over the Raiders last week.
He is yet to run on it and will need to prove his fitness tomorrow in order to be cleared for the do-or-die clash at ANZ Stadium.
Assistant coach Andrew McFadden said he's confident the 25-year-old will play.
"We're hopeful. Roger hasn't run yet but that's just to give him the best chance physically," said McFadden.
"He's obviously played the majority of our games this year so he should be right and Simon [Mannering] had a good run yesterday so we're hopeful.
"He'll definitely have to have a run and that's when we'll get a real indication but he looks pretty good."
A positive sign for Warriors fans is that the fullback was spotted walking freely at Auckland Airport today as the team departed for Sydney.
Should Tuivasa-Sheck be ruled out, utility Peta Hiku will take over the No.1 jersey with Gerard Beale slotting into the centres.
"There is a chance [Roger won't play]," McFadden said.
"He obviously has to be fit, but we're hopeful, but the medical staff say he'll be fine.
"We have Gerard Beale on the bench and Peta Hiku can slot in, if need be. If worst come to worst, we'll be fine."
The Warriors play the Panthers at 7:30pm on Saturday.
