Portuguese winger Jota returns to the Celtic squad after dropping out of the Europa League squad in midweek as he was not registered. Summer signing Landon Emenalo is fit after his rehabilitation at parent club Chelsea and could be added to the squad. Cameron Carter-Vickers (hamstring) is a doubt and Yang Hyun-jun and Alistair Johnston (hamstring) are set to remain sidelined. Hearts will have Tomas Magnusson available after suspension, but Ageu (muscle), Craig Halkett (Achilles), Blair Spittal (shin) and Tom Renaud (ankle) are out.
