CELTIC will be without key midfielders Scott Brown and Shaun Maloney for their Europa League clash against Hamburg.
Both players were absent from Saturday's 3 - 0 league victory over Kilmarnock and did not fly out with the rest of the squad which
left for Germany.
Brown is sidelined with an ankle injury while Maloney is out with tendonitis in his achilles.
The Parkhead side, currently sitting bottom of Group C, must win if they are to stand any chance of qualifying for the next round of the Europa League.
