Celtic manager Neil Lennon faces a nervous wait on the injury news of defender Kristoffer Ajer, as reported by the Daily Record.
The centre-back has suffered a recurrence of the groin injury picked up in the Europa League draw at Lille last month.
Ajer missed games against Aberdeen and Sparta Prague due to the problem, before returning to start in Saturday’s win at Motherwell.
But the defender limped off late on in that victory after agitating his initial groin injury.
Despite the current situation, Norway manager Lars Lagerback has called up Ajer for the country’s upcoming matches against Israel, Romania and Austria.
Speaking on the player’s current availability, Lagerback said: “We do not know for sure. We have only had audio contact so far.
“We do not know how serious it is.”

Crucial period for Lennon’s outfit
Celtic return after the international break with a trip to fourth-placed Hibs, before travelling to Sparta Prague in the Europa League just five days later.
Lennon’s side have plenty to do in both competitions. They sit second in the league, nine points off leaders Rangers, but have two games in hand over Steven Gerrard’s men.
They face a much more difficult task in Europe, however, where they sit bottom of their Europa League group, having picked up just one point from their three matches so far.
Kristoffer Ajer a potential big miss for Norway
Kristoffer Ajer has played every minute of Norway’s five matches this year, helping his country to second spot in their Nations League group, level with leaders Austria.
The 22-year-old was, however, unable to prevent Lagerback’s side from losing their Euro 2020 qualifying play-off meeting with Serbia, with the visitors winning 2-1 after extra-time.
They now have a friendly with Israel on Wednesday, before completing their Nations League tournament at Romania and Austria on Sunday and Wednesday respectively.
