Didier Drogba is to have an operation to remove screws from his arm as he serves his domestic suspension.
Drogba was given a three-match ban after his dismissal during Chelsea's recent 1-0 defeat to QPR and, although he has already missed two domestic games, he will now go under the knife to remove screws inserted ahead of the 2010 World Cup.
He will miss Tuesday's visit to Genk in the Champions League and then sit out the final game of his suspension at Blackburn on November 5. Drogba may also be unavailable when Ivory Coast take on South Africa in the 17th edition of the Nelson Mandela Challenge on November 12, but he is set to be fit for Chelsea's game against Liverpool on November 20.
"[Drogba] should be ready for the team when the others go away for international fixtures," Andre Villas-Boas said. "We took the risk based on his domestic suspension and the forthcoming international break to remove six of the eight screws from his arm."
