Assassin may nominate one of the two face down cards that are not in play?

Yes. The Assassin names a Role (not a player) who will lose his turn. If the role is out of play this turn, he wasted his ability.

In theory, the Assassin may also name the face-up Role which is not in play, if he feels like wasting his ability for some reason.
