Barca's back-up keeper Cillessen will miss 3 Clasicos as he is out for 6 weeks.
In training today, Cillessen tore a muscle in his right calf and he will be out for around six weeks.
The Dutch stopper would have been used in the Copa del Rey against Real Madrid on Wednesday and in the semi final second leg in three weeks’ time.
The stopper has been superb whenever called upon by Ernesto Valverde and that was his competition.
Barcelona announced the news while also publishing their squad list to face Valencia on Saturday at Camp Nou, which obviously Cillessen is not on.
Sergi Samper is in the squad for the suspended Sergio Busquets, while Inaki Pena, the B team goalkeeper replaces Cillessen.
