West Bromwich Albion have informed Terry Burton and Mervyn Day that their services are no longer required at The Hawthorns.
As part of the club's "ongoing" backroom overhaul, Burton has left his post as technical director, while Day has lost his job as head of recruitment.
"Both Terry and Mervyn depart with our best wishes for their future endeavours and gratitude for their efforts during another demanding season," chairman Jeremy Peace told the club's official website.
"But I am on record as saying the club would be engaged in an ongoing review at all levels and it was felt changes were required."
Peace also confirmed that both men would be replaced, but the club is in no hurry to make appointments.
