Rangers manager Walter Smith is annoyed with Madjid Bougherra after the Algeria international returned to Glasgow late following his country's World Cup play-off victory against Egypt last Wednesday.
The defender could miss this week's Champions League clash with Stuttgart after failing to make himself available for Saturday's 3-0 victory against Kilmarnock.
"I'll probably speak to him today (Monday) at some stage," said Smith. "It's obviously a concern but it's happened and we just have to handle it. We'll just get on with it.
"We aren't the first club it's happened to and we won't be the last. We've not selected the team yet and we'll sit down and do that after training."
