Full-back Lenny Sowah has also departed following the end of his deal and Accies announced that midfielders Tom Taiwo and Delphin Tshiembe had left by "mutual agreement".
St Johnstone striker David McMillan returns to Perth following his loan spell while Tony Andreu's loan stay has finished. The Frenchman is soon to be out of contract with Coventry.

A club statement read: "Further ins and outs will happen over the close season. We wish all departing players good wishes for the future."
