Aston Villa have confirmed winger Charles N'Zogbia has suffered an Achilles tendon injury.
A statement on the club's website said N'Zogbia sustained the injury while keeping fit on holiday in Miami and had undergone surgery in the United
The club did not reveal how long they expected N'Zogbia to be sidelined but Roddy MacDonald, head of sport and exercise medicine, has travelled to the US and will accompany the Frenchman back to Birmingham next week.
Villa boss Paul Lambert said: "The priority is to ensure that Charles receives the very best care, and he has done and will continue to do so throughout his recovery period.
"It's a blow for Charles, obviously, but he'll get his head down and get himself fit again and he'll have plenty of support in doing so."
