Bradford Bulls have announced that head coach James Lowes has stepped down from his role because of personal reasons.
The 46-year-old joined the club in the summer of 2014, but has opted to leave with the Bulls fourth in the Championship table.
A statement from Lowes said: "This decision has come with a heavy heart and I have had to make this tough call for personal reasons, and I request everyone respects that.
"I would like to personally thank the players, directors, staff and especially, all the supporters of this great club for my time here."
Assistant coach Matt Diskin will take temporary charge of the team.
