Inter have confirmed that Alexis Sánchez has undergone surgery on his ankle to address the injury which he picked up on international duty.
The winger suffered tendon damage in his ankle whilst away with Chile, and he was sent to Barcelona on Wednesday to meet with a surgeon to assess the severity of the injury.
As noted by the club's official website, Sánchez met with specialist Dr Ramon Cugat, who recommended that surgery was the way forward. He has now had the operation, which Inter say was a success.
There is no mention of how long Sánchez will be on the sidelines for, but Chile manager Reinaldo Rueda suggested that it could be up to three months before the winger is able to return to action.
