The Warriors hope to know in the next 48 hours whether off-contract hooker Issac Luke will re-sign for next season.
The club is still waiting to hear whether the 31-year-old will agree to take up a modest one-year deal, with a rival offer from Newcastle reportedly on shaky ground.
The Knights recently tabled a one-year offer for the 254 game veteran with an option for a second season in the club's favour.
That offer is understood to be short of the lengthy term Luke is seeking, while the Knights reportedly have concerns about signing the Kiwi international, who is booked in to have shoulder surgery on Thursday.
The Warriors have so far been patient in waiting for Luke to make a call on his playing future but want the matter resolved as soon as possible.
