A sport jacket really is too casual for the "modified formal" standard of dress of the "formal" evenings. If one does not have a tuxedo or a dinner jacket, the substitute should be a dark -- and I do mean DARK -- business suit.
Celebrity eliminated the dark from their suit definition about two years ago. They only request a Tuxedo, dinner jacket or suit...
Cocktail dress, gown or dressy pantsuit
Tuxedo, suit or dinner jacket with slacks
