Lyon defender Christophe Jallet looks set to miss at least this weekend's Ligue 1 trip to Guingamp after suffering a reported dislocated shoulder during France's 2-0 friendly win over Denmark on Sunday evening.
The 31-year-old was forced off the pitch late on at St Etienne's Stade Geoffroy-Guichard after hurting his right shoulder, and now looks set for a spell on the sidelines.
OL president Jean-Michel Aulas tweeted: "It's sad news for Jaja, to whom we wish a speedy recovery."
Lyon are currently second in Ligue 1, one point behind Paris Saint-Germain.
