Celtic face losing the services of Daniel Arzani and Eboue Kouassi for the remainder of the season.
Kouassi was injured against Hearts at Murrayfield on Sunday and has been diagnosed with a knee ligament injury.
Arzani made his debut at Dundee on Wednesday but was taken off.
“We are waiting on the final analysis of the scans but it is unfortunate. It looks like we will have two cruciate injuries,” said Celtic manager Brendan Rodgers.
“If it is the case it will rule them both out for the rest of the season.”
