Fulham defender Philippe Senderos is expected to be out of action for around six months due to a ruptured Achilles tendon.
The Swiss Football Association confirmed the extent of the damage on Wednesday after the former Arsenal player was injured during a training session in London on Tuesday.
Senderos had been named in Swiss coach Ottmar Hitzfeld's squad for Wednesday's friendly against Austria but withdrew due to a toe injury and had reportedly been training alone when the Achilles injury struck.
"It's incredible bad luck for Philippe. A hard blow to him personally, for the club, but also for the Swiss national team," said Hitzfeld.
