Tottenham Hotspur midfielder Sandro will be on the sidelines for three months after recently undergoing knee surgery.
The 22-year-old Brazilian returned to the UK this week after suffering the injury on international duty with Brazil.
"Following consultation with an independent knee specialist, Sandro underwent surgery on his left knee in London. Scans confirmed he had torn his lateral meniscus, as well as suffering a calf strain. The specialist has advised a three-month rehabilitation period before a return to full training," read a statement on the team's website.
The Brazilian made 19 league appearances, eight of them from the bench, for Tottenham last campaign, scoring his only goal in the defeat to Chelsea in April.
