The 22 year old is experienced within the Super League competition, already making 50 first-team appearances in his career.
Playing as a fullback/winger, Ian has progressed through the ranks at Saints. He established himself as a first-team regular in 2004, aged 18, making 21 appearances and consolidated his position in Super League X.
Hardman has a great vision for the game and is a welcomed addition to the side. Hull Kingston Rovers Head Coach Justin Morgan said: “Ian is player of great ability and he will add a touch of flare to our backs. This opportunity to bring him in on loan will give us great cover for Byron Ford who sustained an injury during the Easter period.”
