Town's crunch trip to the City Ground to be broadcast live
Blues will kick-off at the City Ground at midday on May 7 with the hosts in danger of being relegated.
Forest are locked in three-way last day shoot-out with Blackburn and Birmingham, who are two points better off than their rivals.
Rovers, managed by former Town skipper, Tony Mowbray, are in action at Brentford, while Birmingham are at Bristol City.
Forest and Blackburn are separated only by goal difference with Forest one goal better off but if both win and Birmingham fail to win at Ashton Gate, they will go down because of an inferior goal difference.
Forest won at Portman Road 2-0 back in November in front of the live Sky TV cameras.
