The Swede was left out of the starting XI in Saturday’s win over Brentford but is likely to play alongside Miguel Almiron and Anthony Gordon in attack.
Callum Wilson, who scored the winning goal against the Bees, trained individually in the lead-up to the game but is not believed to have an injury.
Another expected signing is Sandro Tonali, as the Italy international returns to his former club and the team he supported as a boy.
Joelinton sits on the treatment table alongside Joe Willock, Emil Krafth and Javier Manquillo and will miss the game.
Newcastle Predicted XI: Pope; Trippier, Schar, Botman, Burn; Guimaraes, Tonali, Longstaff; Almiron, Isak, Barnes
Injured: Joelinton, Willock
