The French club have also been given a transfer ban after racking up more than £500million in debt.
According to talkSPORT's Ben Jacobs, the club were due to appear before France's financial football watchdog, the DNCG, on Friday morning.
This was to discuss the future of its operations.
The club, whose majority owner is Crystal Palace co-owner John Textor, were confident they could convince the DNCG that Lyon will be in a better financial situation come the end of the season.
French outlet L'Equipe reports chiefs were going to detail the potential sale of players from their stock or that of their Brazilian club Botafogo, as well as the sale of Eagle Group's 45 per cent share in Crystal Palace, to the DNCG.

Now, though, the club have been handed severe sanctions, with them needing to get their finances in line before the end of the season to avoid relegation.
They will need circa €100m (£91m) in revenue to escape their current punishments.
Their payroll is now also controlled by the DNCG.
Former Ligue 1 winners Girondins Bordeaux suffered similar punishment before they were relegated to the fourth tier of French football.
