Gary Roberts, Franny Jeffers, Ian Craney and John Keeley depart Portman Road
John McGreal will be in charge of Town for Tuesday night’s trip to Charlton.
The former Blues defender has been named as the Club’s interim manager following the departure of Paul Cook at the weekend.
Rene Gilmartin, who was John’s assistant during his short spell at Swindon Town, will join him in the away dugout at The Valley.
John will also be assisted Town U23s coach Kieron Dyer and head of academy goalkeeping Carl Pentney.
Gary Roberts, Franny Jeffers, Ian Craney and John Keeley have all departed Portman Road alongside Paul.
The Club would like to thank them all for their efforts and wish them the best for the future.
