Celtic striker Moussa Dembele will miss the Champions League qualifier with Rosenborg with a hamstring problem.
"It was just a minor strain," said manager Brendan Rodgers. "Sometimes the hamstring can be six to eight weeks but this one, from the time it happened, we were told two to three weeks maximum."
Dembele scored twice in Celtic's 3-0 victory in Glasgow before limping off in the second half.
