Saints Academy Manager Simon Sinclair will leave the Club at the end of the season to take up a role with Bedford Modern School.
Sinclair, who has had a 14-year association with Saints as a coach, is to join Bedford Modern School as Director of Sport.
“Simon’s contribution to Saints has been outstanding,” said Northampton Saints CEO Mark Darbon.
“For the last 14 years he has been dedicated to helping develop and progress some of the players we see week in, week out at Franklin’s Gardens.
“He remains one of the most popular figures here at Saints and although we are always disappointed to see someone of his calibre go elsewhere, he leaves with our very best wishes.”
