The LFP's Competitions Commission has overturned Nantes's opening-day victory against Bastia, after the club was found guilty of fielding suspended player Abdoulaye Toure.
Bastia will now be awarded all three points, but both sides will be awarded no goals towards their league statistics.
Nantes fielded Toure as a 67th-minute substitute, despite the player receiving a suspension from the Federal Disciplinary Committee after an accumulation of bookings in all competitions in the previous season.
As a result of the decision, Nantes now have 30 points in the Ligue 1 standings.
