RICHMOND is now searching for up to five new assistant coaches.
The future of Mark P. Williams is also unclear, with the Tigers yet to confirm what role he will play at the club in 2017.
The departures leave the highly rated Ben Rutten as Hardwick's only remaining assistant coach, with development coaches Ryan Ferguson and Andrew McQualter also still at the club.
Interviews for the group's replacements are under way and will continue when incoming football manager Neil Balme starts in his new role on Monday.
The club has met already with assistant coaches Brett Montgomery and Blake Caracella, who are both completing the AFL's Level Four accreditation course.
The Tigers face a challenge in filling up to five vacancies but could turn to retired defender Troy Chaplin, who impressed in the last six weeks of the season in an off-field role assisting the coaches.
