The 24-year-old, who came back to play in six matches at the end of last season after a groin operation, picked up the injury to his left leg, during the 6-0 pre-season defeat against Arsenal in London last Saturday.
He will undergo surgery in Lyon on Friday.
Grenier, was initially included in Didier Deschamps' France squad for last year's World Cup, before breaking down and missing the tournament.
Lyon have qualified automatically for the Champions League group phase, for the upcoming campaign, after finishing second in Ligue 1 last season behind champions Paris Saint-Germain.
