Bradford have signed young centre or back-rower Callum Bustin on loan from Castleford.
Bustin, 20, was released by London Broncos midway through last season but was picked up by the Tigers.
He made 14 appearances in 2017 for four clubs, including the Broncos, London Skolars, Newcastle Thunder and Oxford.
Bulls co-owner Andrew Chalmers said: “He’s an impressive young talent and someone that we have been keeping an eye on for a long time.
“Joining our scheme this year will not only benefit Callum, but also our great club. He’ll be able to really prove himself in the upcoming pre-season games and begin to blend into the team as a vital member of the squad.”
