The Potters have annouced their annual retained list, and its bad news for four first team squad members.
Striker Vincent Pericard along with ex-academy graduates Tom Thorley, Marc Grocott and Jimmy Phillips have all been released after their contracts run out.
19-year-old goalkeeper Danzelle St.Louis-Hamilton, who recently spent three months out on loan at League One side Bristol Rovers, has agreed a new 12-month deal whilst a one-year extension has been offered to Salif Diao, but this has yet to have been accepted by the Senegalese international.
All but one 2nd year academy players were released, with highly rated midfielder Nathaniel Wedderburn the only survivor.
Loanee's Stephen Kelly and Henri Camara have returned to Birmingham and Wigan respectively leaving the Potters with a current squad of 29 professionals awaiting Diao's reply
