Ange Postecoglou expects to be without Mikey Johnston "for a little while" after another nightmare injury blow for the forward.
The skilful attacker was sidelined for the majority of last season and the start of the current campaign with a series of niggling injuries.
He had ramped up his return under Postecoglou but limped off in the Scottish Cup win over Raith Rovers.
The Australian will be unable to select the 22-year-old for the Europa Conference League clash with Bodo/Glimt.
However, right-back Josip Juranovic does come back into the squad to face the Norwegian champions having missed the last two games.
Yosuke Ideguchi has also ramped up his return from injuries which have hampered his early Celtic Park career.
But he is unable to feature against Bodo/Glimt as he has not been registered for Celtic's European campaign as the club were only able to register three of their four first-team January arrivals.
Postecoglou said: "From last weekend, Mikey Johnston picked up an ankle sprain, nothing too serious but it will keep him out for a little while.
"Everyone else came through okay, Josip Juranovic is available, he's back training after missing the last couple of games.
"That's it. Yosuke Ideguchi is not registered (for Europe) so he won't be available but everyone else is okay."
