Bastia defender Gilles Cioni will be out for around a month with a fractured jaw, the Corsican club have announced.
Cioni was forced off late in Saturday's 1-0 win at Reims having earlier being caught by the elbow of opponent Prince Oniangue, who was booked for the challenge.
A statement on Bastia's website read: "Gilles Cioni will be absent for a minimum of four to five weeks. The defender had scans on Monday morning which revealed a fracture."
