Lyon ave Michel Bastos has revealed he will miss Wednesday's Champions League tie against Real Madrid through injury, although the nature of the problem is unknown.
The French champions host bitter rivals St Etienne in Ligue 1 on Saturday before entertaining Jose Mourinho's side at Stade Gerland, who demolished Lyon 4-0 last week.
Lyon are third in Group D with Madrid comfortably leading the pack on nine points, five points clear of Ajax.
Bastos will join Argentine striker Lisandro Lopez on the sidelines as he is still missing with the ankle injury that has ruled him out for eight weeks.
Bastos wrote on Twitter, "Bad news my friends; I'm injured and I will be out of action for three to four weeks."
