i'm making a fan game and if i mention fnaf itself will i get sued?

the game i'm making is like a sister location to freddy's and goes by "Luna's Diner". i'm modeling all new characters and the fnaf mention is very brief in a phone call and the missing children are mentioned as well. i don't want to get into legal trouble, i will mention FNAF belongs to Scott Cawthon and that it's a fan game, will that be enough?
