"In application of articles 124 of the FFF (French federation) regulations and 407 of the LFP regulations, the Disciplinary Committee will investigate 87 players from professional clubs who have failed to abide by the betting ban on LFP sanctioned games," the LFP said in a statement.
The LFP added, however, that there was no suspicion of any match-fixing.
Professional soccer players have been barred from betting on LFP matches since Feb. 1, 2012.
