Warrington Wolves centre Rodrick Tai is leaving the club, while Sam Stone is joining from Salford Red Devils for the 2026 season.
Tai, 26, scored 13 tries in 41 appearances after signing from PNG Hunters but will not return next year.
Australian forward Stone joined the Wire on loan from Salford in June this year and scored three tries in 12 Super League appearances.
He has now signed a permanent two-year deal, while Alfie Johnson has left to join Championship side Halifax Panthers.
In a busy spell of restructuring, Toby King, Jake Thewlis, Sam Powell and Jordy Crowther have all signed new contracts.
Thewlis, who scored 14 tries in 19 appearances on the wing, has signed a two-year deal, King and Powell have signed new one-year deals, while Crowther has signed until the end of the 2027 season.
