Venter to replace Jones

Jones cited family reasons for his decision to leave Vicarage Road just one season into a three-year deal, although it has been reported he is unhappy with the new management regime at the club.

"After careful consideration, I have decided to leave Saracens at the end of the current season. My reasons are entirely personal," said Jones, the former Australia head coach. "My wife and daughter have always given me unqualified support but it is now time for me to put the family needs first."

He added: "Naturally I remain 100% committed to the Saracens cause and eagerly look forward to building on the progress we have made this season and ensuring we challenge for a top-four finish in the Premiership and maintain our strong momentum in the European Challenge Cup."

Jones led Australia to the 2003 World Cup final and helped South Africa go one better in 2007 after being brought on board by head coach Jake White.

Jones first linked up with Saracens in 2006 in an advisory capacity before succeeding Alan Gaffney as director of rugby last summer.

He has recruited England captain Steve Borthwick and overseen the promotion of academy stars like Noah Cato and Alex Goode into the first XV.

The seamless transition of power between Gaffney and Jones was seen as the start of a period of much needed stability at Saracens after years spent chopping and changing coaches and players.

But Venter will take over next season as Saracens' seventh boss in as many years and further strengthen the club's South African connection.

Venter, the former Springboks and London Irish centre, is currently defence coach with the Stormers and will take charge from July 1.
