The Nottingham Forest boss is one of four names reportedly in the frame to succeed Chris Hughton after he became the new manager of Norwich City, former City Ground supremo Colin Calderwood following him to Carrow Road.
While wild rumours of Neil Warnock being lined up by potential new Forest owners continue to circulate, the Birmingham Mail reports on Wednesday that Blues are unlikely to approach a manager currently in a job elsewhere.
Acting chairman Peter Pannu is overseeing the appointment of a new boss with former Huddersfield chief Lee Clark now the clear favourite.
