Alexander Lacazette, Lyon's top goalscorer, was not in the squad but tweeted: "Pffff shameful!"
With tensions running high going into the game, home fans invaded the pitch as OL players were warming up and attacked the visitors. However, after further chaos at half-time, the league's authoritative body, the LFP, has made a decision to put a stop to the game.
The Lyon team ran to the dressing room after the Corsican club's supporters charged onto the field at the Stade Armand Cesari and threw punches at the visiting players. The French league said in a statement that, after the first trouble, it had been decided that the match could go ahead but would be stopped if another incident happened.
Lyon players fled the pitch after a pre-match training session when they were charged by supporters of Corsican side Bastia, with kick-off delayed for almost an hour.

"The players then huddled together. Both they and the coaching staff are very shocked", said Berthod.
L'Equipe journalist Vincent Duluc was quoted on the OLTV account as saying: "Memphis was pushed by a supporter".
Smoke from something thrown onto the pitch as Lyon's Corentin Tolisso, center, celebrates scoring a goal during the Europa League quarterfinal soccer match between Lyon and Besiktas, in Decines, near Lyon, central France, Thursday, April 13, 2017. "I've never seen anything like it in 30 years".
UEFA has opened disciplinary proceedings against Lyon and Besiktas and there will likely be a French league investigation into the latest events, with the LFP adding: "The LFP asked SC Bastia to take all necessary measures to allow stadium bans to be imposed on the individuals responsible for these actions".
