Reid will take temporary charge at the City ground.
Chris Hughton has been sacked as manager of Nottingham Forest.
The former Republic of Ireland player and coach has been shown the door following last night's 2-0 defeat to Middlesbrough.
The result means Forest are botton of the Championship with just one point from seven matches.
Another former Irish international, Steven Reid, will take temporary charge at the City ground.
