The France Under-21 defender sustained the injury in the second half of Saturday's 1-1 Ligue 1 draw at OGC Nice and club doctor Jean-Jacques Amprino believes he will be sidelined for three weeks. The 21-year-old's absence is a blow to Lyon who are already without regular left-back Eric Abidal for three months due to a broken foot. Versatile defender Sylvain Monsoreau is likely to fill the void.
However, there was better news for Lamine Diatta, who was also forced off at the weekend with a shin injury. The Senegalese defender required a trip to hospital but a scan revealed no fracture and the 30-year-old could return for UEFA Champions League Matchday 6 on 6 December.
