The Iceland international, 35, has been ruled out of the sold-out clash with a hamstring injury picked up in the 3-0 win over Nottingham Forest on Saturday.
Rudy Gestede, his replacement against Billy Davies' men, scored twice to secure three points which leaves City needing just a point against the Addicks to secure Premier League football. He is competing with Joe Mason for a start.
Fellow striker Fraizer Campbell (ankle) and defender Matt Connolly (groin) will not feature having both missed the Forest victory.
But manager Malky Mackay has revealed that Nicky Maynard, who made just three appearances following his move from West Ham before suffering knee ligament damage back in the autumn, is back in full training and could even make an appearance before the end of the season.
