Fifteen professional players are being investigating by the French Football League (LFP) for breaking anti-betting regulations, the LFP said on Wednesday.
The regulations state that no player, referee or staff member is allowed to bet on "competitions organised by the LFP".
In the 2013/14 season, 87 professional players were found guilty of betting offences by the LFP, with 37 of them being sanctioned with fines.
