28-year old Dutchman Loovens lasted just 18 minutes of yesterday’s 2-1 win over Aberdeen with a hamstring problem whilst 22-year old striker Bangura missed the clash due to a knee injury.
Celtic boss Neil Lennon confirmed both players would have scans today as he continues to deal with an increasing number of bodies in the treatment room.
"We lost Glenn through a hamstring injury so we have to wait and see the extent of that tomorrow," said Lennon after Sunday’s win.
"It could be a reoccurrence of the injury he had, we are not sure but he was feeling it and he will have a scan.
"We lost Mo Bangura yesterday, he has a swollen knee and he is going for a scan tomorrow as well so we don't know how long, if any length of time at all, he will be out for.
"We are up against it but I am really pleased with the players, especially the ones who played against Rennes on Thursday."
