Hull FC have named former Leeds forward Andy Hay as their new assistant coach as they look to complete their backroom team for 2012.
It follows the appointment of captain Lee Radford to a similar role under new incoming head coach Peter Gentle.
Hay told the club's website: "Hull have been a sleeping giant in recent seasons but the potential here is massive."
Hay, 37, was a strong running forward for Sheffield Eagles before earning big money moves to Castleford and Leeds.
His performances were good enough to earn him selection for the 2000 World Cup, when he played two matches for England.
Hay has spent six seasons at Castleford in an assistant coach capacity but has chosen to move following the departure of former Tigers' coach Terry Matterson.
New Hull coach Gentle is due to start work at the end of October, with pre-season training begining in mid-November.
