Joe Ledley and Beram Kayal will undergo scans on Wednesday after sustaining injuries in Celtic's victory over Helsingborg.
Kayal, who was substituted at half-time in the 2-0 Champions League play-off round win, took a knock to his ankle during the first half.
Ledley meanwhile has a groin injury and manager Neil Lennon will nervously await the result of the scans, ahead of the weekend trip to face Inverness Caledonian Thistle.
Central defender Thomas Rogne also sustained an ankle injury during the game and will be monitored when the squad return to training at Lennoxtown on Thursday.
