Striker Noel Hunt is among the players leaving League One club Southend United this summer.
Midfielder Kevan Hurst's departure from Roots Hall had already been confirmed earlier in the week.
Hunt, winger Myles Weston, plus defenders Cian Bolger and Luke Prosser will leave when their contracts expire.
Midfielder Gary Deegan has had his contract terminated by mutual consent, while Jamar Loza's loan deal from Norwich will not be made permanent.
Sam McQueen and Glen Kamara will also return to their parent clubs, Southampton and Arsenal respectively, after loan spells at Roots Hall.
