New Zealand international Old has been granted a British work permit and is clear to join his new club after impressing in a lengthy trial.

Old has been at the club since late January, where one of his new teammates is former Australian Under 20 international Danny Invincibile.

Kilmarnock manager Jim Jefferies told the Kilmarnock Standard: "Having had Steven here on trial since January 22, it shows you how keen we were to get him.

"It's been a long process because there was so much information to gather and contracts to negotiate before going to the work permit appeal panel."
