An alternative slot of Friday 15 May, at 20:00 BST, has been proposed, should Forest beat Aston Villa in the semi-finals of the UEFA Europa League.
This would enable them to have time to prepare for the showpiece occasion in Istanbul, against either Braga or Freiburg.
The second leg of the tie with Villa is being played on Thursday 7 May, when the matter will become clear and confirmation of our game will be possible.
