Derby have handed a trial to former Bristol City defender Clayton Fortune. The 23-year-old was released by City in the summer and rejected an offer from Port Vale where he spent seven months on loan last season.
The left-back moved to Aston Gate in 2000 from Tottenham Hotspur, where he had been a trainee.
Meanwhile, coach Steve Taylor, physio Dave Galley, sports therapist Faz Page and sports scientist Wayne Campbell have all left Pride Park.
The quartet's departure comes as part of new boss Billy Davies' restructuring plans.
