FOREST GREEN have confirmed former captain Aarran Racine, Fabien Robert, Rhys Murphy and Rob Sinclair can find other clubs.
The quartet have spent pre-season with the academy.
A statement on the club website, said: "We are supporting these players to find opportunities at other clubs."
Robert and Murphy have two years left on their current deals.
Elsewhere, French goalkeeper Simon Lefebvre has left Forest Green by mutual consent.
Lefebvre joined the club in July 2016 on a two-year deal, but has been training with the academy. He dropped down the pecking order after Rovers signed former Port Vale keeper Harry Pickering as third-choice behind Chelsea loanee Brad Collins and Sam Russell.
