Fulham defender Philippe Senderos has had an operation on his ruptured Achilles tendon in Finland in a bid to speed up his recovery, his father told a Swiss newspaper on Thursday.
"He called me as soon as he came out of the operating room. He was anxious before the operation. But everything went well," Julian Senderos told the Tribune de Geneve after surgery late Wednesday.
Senderos said the Finnish clinic was also used by David Beckham after he injured his Achilles tendon while playing for Milan last March.
"Philippe is obviously really downcast. He really wanted to get back to his best form, to get involved at Fulham, and with Switzerland as well. It's not easy to accept," he added.
The 25-year-old former Arsenal player, who moved to Craven Cottage in June, was injured while training in London after withdrawing from the Switzerland squad that beat Austria on Wednesday.
The injury leaves Fulham's new coach Mark Hughes with only two fit recognised centre-halves for six months, with the new English Premier League season due to kick off on Saturday.
Switzerland coach Ottmar Hitzfeld said it was also a setback for his side three weeks before their opening Euro 2012 qualifier against England.
