Hull City have parted company with former first-team coaches Steve Wigley and Stuart Watkiss.
The departures were expected after Steve Bruce replaced the sacked Nick Barmby as manager last week.
Fitness co-ordinator Shaun Rush is also believed to have left the club, but goalkeeping coach Gary Walsh - a former team-mate of Bruce - is to stay on.
Bruce is believed to have made approaches to fill the vacancies but nothing has been firmed up yet.
However, BBC Radio Humberside is reporting that Eric Black, who worked as assistant manager to Bruce at both Sunderland and Birmingham, is unlikely to be one of those coming in.
