Nottingham Forest owners, the Al-Hasawi family, have sacked a number of key figures at the Championship club.
CEO Mark Arthur, chief scout Keith Burt and club ambassador Frank Clark all have been dismissed.
All three men had long associations with Forest, with Clark serving as chairman, manager and as a player over the course of 38 years.
The club recently appointed Alex McLeish as manager following the sacking of Sean O'Driscoll.
