Conference side Dover Athletic have announced they will not offer new deals to six players, including midfielders Barry Cogan and Solomon Taiwo.
Christian Nanetti, Adam Mekki, Jake Reid and Joe O'Cearuill are also leaving the Crabble.
However, all six will be invited back for pre-season training by the Whites if they cannot find other clubs.
Defender Sean Francis has turned down a new deal to join Bromley, who were promoted from Conference South.
Last month Dover signed Kidderminster defender Jamie Grimes, while goalkeeper Mitch Walker agreed a new contract with the club.
