Names that have popped up over the past few days include Mark Kerr from north of the border. Kerr who is a defencive midfielder was linked with the Whites in March as a potential summer target. Nothing has been confirmed but it is thought that Irvine is a keen admirer.
As Preston look to see some activity up front Irvine is set to make his mind up on loan player Beattie from West Brom. It is also thought from reports from across the Atlantic that Taylor Twellman is still interested in signing for the Whites. Preston had to substantial offers of around £1.3 million turned down in January despite the New England striker wanting to move.
