Valencia defender Philippe Senderos has been ruled out of action for the next 10 days with a hamstring injury.
The Switzerland international, who moved to Los Che from Fulham in January, picked up the injury during a training session this week.
Subsequent tests have revealed that the centre-back has suffered a hamstring strain, which will rule him out of Thursday's Europa League clash with Ludogorets Razgrad and Sunday's league tie with Villarreal.
Valencia are also still without the services of Pablo Piatti, who has an ankle injury.
