York City Knights have signed half-back Lee Williams from Hull FC.
Williams, 19, has joined York on a one-year deal with the option of a second after spending the last season full-time at the Super League club.
Knights coach Chris Thorman said: "Lee was at Hull whilst I was there and was always considered to be a good up and coming player.
"He has decided to try his luck in the Championship and I am sure he will prove to be a good signing."
Thorman added: "With the signings of Jamie Ellis and Brett Seymour and the other half-backs already at the club (Hull FC) Lee's chances were always going to be limited."
Williams signed for Hull aged 16 after representing England at Under-15 and Under-16 level.
