Panthers had big wraps on Fearnley.
He is expected to join prop forward Joshua Finau on the Sharks' development list in 2023.
The Sharks currently hold a decent stable of halves to cover the likes of Matt Moylan and Nicho Hynes, with Braydon Trindall, Connor Tracey and Lachlan Miller all capable of filing into the No. 6 or 7 jumper.
Craig Fitzgibbon is likely to hand Puru an opportunity with some of the first-grade talent in the 2023 trials, though Moylan and Hynes firmly have a grip on Cronulla's starting halves spots after guiding the club to a 2nd-placed finish in 2022.
