"I approached Scottish Rugby and asked for a release from my contract under compassionate grounds. Fukofuka says Scottish Rugby has been understanding of his decision - and that it had nothing to do with the governing body or its rugby programme. Scotland next face Canada in six weeks time and Fukofuka is backing "first-class individual" Butcher to succeed in the role. Scottish Rugby performance director David Nucifora added: "Whilst we are disappointed to see him depart, we fully respect and understand the reasons why he has made this decision. "During his time in the role, Sione showed great passion and commitment to the national team and the wider women's programme at Scottish Rugby."
