Sale Sharks coach John Mitchell has resigned from his position at the Premiership club after Friday's 33-27 win over Worcester.
Mitchell, who coached the All Blacks from 2002 to 2003, left his position as head coach of South African outfit the Golden Lions in November, after being cleared of misconduct charges by the Johannesburg-based side.
He then took over the reins at struggling Sale but will now return to South Africa prematurely according to Sale Sharks owner Brian Kennedy.
"John was brought in on a consultancy basis with a view to the possibility of being employed in a longer term position within Sale Sharks," Kennedy said in a press statement.
"He has had to return to South Africa for personal reasons which we respect.
"We are grateful for his valuable and insightful contributions albeit for a shorter term than envisaged.
"Steve Diamond, Bryan Redpath and Pete Anglesea will continue to coach the side, implementing many of John's ideas, and building on last nights excellent performance."
The Sharks' win over Worcester moved them to within one point of London Irish on the Premiership table.
Mitchell, who had a spell as player/coach with Sale during the late 1990s, had previously been helping the club on a part-time consultancy basis.
