Parramatta and Wests Tigers are reportedly two clubs that could be in a position to make Johnson a decent offer should he be forced to leave the Sharks.
The Warriors are another club with money to throw around after they opted not to replace Johnson, and in stark contrast to the Sharks predicament, the Auckland-based outfit remain well poised to strengthen their playing stocks if the right player becomes available.
But the Warriors have so far resisted the temptation to try and lure another experienced playmaker and are set to gamble on partnering one of the club's untested young halves alongside veteran five-eighth Blake Green.
Coach Stephen Kearney will test the credentials of former Penrith reserve grader Adam Keighran and Warriors juniors Chanel Harris-Tevita and Hayze Perham during the upcoming trial games against Melbourne and Wests Tigers, ahead of their first NRL match against the Bulldogs on March 16.
But the Sharks continue their nervous wait for the NRL to wrap up their investigation after the game's governing body reportedly finished interviewing Sharks players and officials this week, as speculation grows that their cap breaches could be more serious than first thought.
The investigation has already claimed the career of banned premiership winning head coach Shane Flanagan, with the Sharks appointing his assistant John Morris as his replacement.
It remains to be seen whether Johnson is another casualty and what impact any further sanctions have on their 2019 premiership tilt.
