Nottingham Forest have sacked academy director Nick Marshall, reports BBC Radio Nottingham.
The club are also understood to have parted company with finance director John Pelling, media and communications manager Fraser Nicholson and operations manager Brandon Furse.
Last month chief executive Mark Arthur, head of recruitment Keith Burt and club ambassador Frank Clark also left.
Forest have made no comment yet about the latest departures.
Billy Davies, who Marshall previously worked with at the City Ground during his 16 years with the club, was last week re-appointed as Forest manager just 20 months after he was sacked.
