The Daily Telegraph understands all four players have agreed to terms but the club is reluctant to be caught out with another “Kade Snowden” type announcement until all contracts have been signed.
Fifita is a sensational prospect who played City-Country this year and who recently agreed to a 12-month contract extension at Leichhardt.
Salary cap pressure from signing Adam Blair has now forced coach Tim Sheens to release both players.
De Gois will be returning home to Cronulla after three years in Newcastle, where he was signed to replace local legend Danny Buderus.
He actually agreed to a new deal under the previous Knights management but the offer was withdrawn by the Nathan Tinkler Group.
Local junior Townsend, who made his first grade debut on Friday night against the Broncos, has signed on for a further two years. He’s such an outstanding prospect that Robson from Parramatta will be flat out getting the half-back jersey from him.
The Sharks have also not ruled out offering an early release to struggling back-rower Anthony Tupou, who is soaking up $400,000 of the salary cap.
He is under contract until the end of next season.
