Fulham manager Mark Hughes has been handed some devastating news just three days before the start of the new season after it was revealed that new signing Philippe Senderos could be sidelined until February after rupturing his Achilles tendon.
The central defender suffered the injury while preparing in London for Switzerland's international friendly against Austria.
"It's an unbelievable setback for Philippe, a terrible blow for him, his club but also for the national team," said Switzerland coach Ottmar Hitzfeld.
"Senderos had played an important role in my arrangements for the launch of the European Championship qualification matches. He is a leader, on and off the pitch."
The 25-year-old only signed for the Cottagers in June just before then manager Roy Hodgson left the club to take up the managerial reins at Liverpool. He is expected to undergo an operation by the same surgeon in Finland who treated David Beckham for an Achilles injury in March.
Senderos was a member of Switzerland's World Cup squad in South Africa earlier this summer but suffered an ankle injury in the first half of their opening match, a 1-0 win against eventual champions Spain.
