Pope played the full match on Tuesday night as Vale lost 2-0 at home to Leyton Orient but he has since missed training through illness. Adams hopes his 14-goal striker will overcome the stomach bug and be fit for Sunday's game.
If Pope does not make it Louis Dodds or Jordan Hugill may come into the starting line-up, while the likes of Dan Jones, Chris Lines, Jack Grimmer and Billy Knott provide options for Adams in defence and midfield.
Four defeats in the last five games has seen Vale's play-off hopes fade in recent weeks.
