The disgraced 21-year old defender, who pleaded guilty to sex offences with two girls last year, was sent on loan to Lithuanian club FK Suduva when it appeared his Hearts career could be over.

"My Suduva deal ends in July. I don't know what will happen then. Perhaps I'll return to Hearts," he said.
