Ex-Rangers ace Boyd to take legal action against Eskisehirspor
Boyds agent, Mark Donaghy, confirmed: "Kris has triggered a release clause in his contract. His contract has been terminated because of late payments and a legal process is now under way.
"He will now head back to the UK."
Boyd, who made just two league appearances for the Star of Anatolia, has also lodged a complaint with FIFA regarding his situation.
