Hull FC have released half-back Jacob Miller after agreeing a termination fee with the player.
The 22-year-old joined the Black and Whites from Wests Tigers on a two-and-a-half-year deal in May 2013.
He made 20 Super League appearances, scoring six tries and also started the 2013 Challenge Cup final.
Miller was on a dual-registration contract with Championship side Doncaster this season, having fallen down the pecking order at Hull.
The club said in a statement: "Hull FC would like to thank Jacob for his contribution to the club over the last 18 months."
