COLOGNE, June 24 (Reuters) - Switzerland defender Philippe Senderos will miss the rest of the World Cup after dislocating his shoulder in Friday's win over South Korea, team officials said on Saturday.
Doctor Rudolf Roeder said Senderos had suffered ligament damage in the incident.
'He will be out for a minimum of two weeks. There is a 50 percent chance he will require an operation but the most important thing is rest for now,' Roeder said.
Senderos was part of a Swiss defence that has yet to concede a goal at the World Cup.
'Of course, it is a big blow for us, but we have already seen his friend Johan (Djourou) standing in well in the defence,' said Swiss coach Koebi Kuhn.
'One of our strengths is that we can replace almost everybody in the team without losing too much strength,' he added.
Switzerland play Ukraine in the World Cup second round on Monday. The World Cup final is on July 9.
Senderos scored Switzerland's first goal in the 2-0 win over South Korea on Friday, sustaining a cut on his nose in the process which required stitches at halftime.
He missed last month's Champions League final between his club Arsenal and Barcelona because of a knee injury.
