Jeremy Menez may have to undergo surgery to have part of his ear reattached after a freak accident on his debut for Bordeaux.
The French club were preparing for their upcoming season with a friendly match against Lorient where the incident happened.
The 29-year-old, who recently joined the club from Ligue 1 club from AC Milan, lost half of his right ear when Lorient midfielder Didier Ndong stepped on his head following a challenge.
A statement from the club read: "Jeremy Menez had part of an ear cut off during the encounter against Lorient, which led to his premature exit in the 77th minute.
"The medical staff will take a surgical opinion on whether to operate on the new Bordeaux player."
A shocked Ndong was apologetic for his part in what can only be described as a freak accident.
A statement by Ndong on the club's website read: "I offer my apologies to Jeremy Menez and Girondins de Bordeaux following a totally unintentional play which had unfortunate consequences for the Bordeaux striker.
"I give him my full support for the coming days and hope to see him very quickly on the pitches of Ligue 1."
