Well, piecing together all the clues on here e.g. Surname of G and possibly from Kilmarnock, the player could very well be Gordon Greer. Currently with Kilmarnock, but has played for Blackburn and Stockport (on loan).
In the story below, from May 2007, it says that Greer is looking for a move back to England due to personal circumstances.

I could be wrong, but it makes sense.
