Glenn Hall spent three years with Manly before signing for the Bulls
Bradford Bulls have cut short the contract of Australian prop Glenn Hall by mutual consent.
Sydney-born Hall, 29, who signed from Manly for the 2010 season on a three-year deal, is to return down under, where his wife is expecting a baby.
"We've agreed for various reasons that it's best to go our separate ways," said Bulls chief executive Peter Hood.
"Glenn has at all times proved himself a model professional and we wish him every success in the future".
Hall made 25 Super League appearances for the Bulls, running in two tries.
Meanwhile, the Bulls have named eight of their new winter signings for Jamie Langley's testimonial against Halifax on Sunday.
Patrick Ah Van, Shaun Ainscough, Bryn Hargreaves, Marc Herbert, Gareth Raynor, Ian Sibbit and Chev Walker all feature in a 20-man squad, while Shad Royston makes his first appearance in a Bulls shirt against his former club, for whom he was top try scorer last season.
