Bruno Guimaraes, Lucas Paqueta, Tino Kadwere and Jerome Boateng could all miss Lyon's Europa League meeting with Rangers at Ibrox next week, according to various reports.
French media say Guimaraes, Paqueta and Kadwere could miss out for the French side due to Scottish Government red list rules.
Radio Scoop noted Lyon allowed Brazilian stars Guimaraes and Paqueta and Zimbabwe international Kadwere to head off on international duty in the most recent break, meaning they'd have to observe a hotel quarantine period if they were to travel to Scotland.
Reportedly, Holyrood has already informed the Ligue 1 club the aforementioned players won't be able to cross the Channel to take on the Light Blues next Thursday.
Radio Scoop claims Lyon are "turning to UEFA" to find a solution but it appears their heedless approach to the international break is going to hurt their European aspirations.
Meanwhile, German defender Boateng could also miss the match after appearing in court accused of attacking his ex-girlfriend.
The verdict is due to be heard on the day of the Gers game with the former Bayern Munich man potentially facing five years in prison for allegedly injuring his former partner in a dispute on holiday.
The 33-year-old, who joined Lyon on deadline day and is yet to play for the French giants, denies any wrongdoing but prosecutors have accused him of wilful bodily harm.
German media say four witnesses will be called in court and a verdict could be delivered on Thursday - the day Boateng is due to help a struggling Lyon side as they face Steven Gerrard's men.
