CALLUM Bustin this afternoon signed a permanent deal with the Bulls.

The powerful forward has been a key figure in the promotion push while on loan from Castleford Tigers.

And he has now put pen to paper on a contract that will tie him to Odsal until the end of 2019.

Coach John Kear is delighted to pin down Bustin, who has scored four tries from 13 appearances.

He said: "Castleford have been great with us, we have agreed terms with Callum for next year and part of that agreement is that he is released from Castleford, so he becomes our player for 18 months.

"We have got a really good relationship with Jon Wells and Daryl Powell and I would like to thank them for their help with James Green and Callum.

"He is young, raw and an emerging prospect, but he is also 119kg, so he is big.

"He’ll benefit from James Green being here, just as he looks up to Steve Crossley as a sort of mentor and leader, as all of the forward pack do."
