Kris Boyd has terminated his contract with Turkish club Eskisehirspor and started legal proceedings against them for alleged loss of earnings.

Boyd: Eskisehirspor departure

The Scottish Premier League's all-time highest goalscorer has left the club only five months after joining them from Middlesbrough on a lucrative three-year contract.

Boyd's agent, Mark Donaghy, has confirmed that the former Rangers and Scotland striker will be available to join another club in next month's transfer window.

"Kris has triggered a release clause in his contract." Donaghy told Sky Sports News.

"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."

It's believed Boyd has yet to receive a monthly salary from Eskisehirspor after he received a signing-on fee in July.

Eskisehirspor are currently five points behind leaders Galatasaray, and are understood to have made repeated requests for Boyd to stay.

Boyd, 28, featured in just two games for Eskisehirspor during his stint with the club - playing just 76 minutes of football all season.
