Valencia will be without attacking duo Santi Mina and Nani for Sunday's trip to Barcelona in La Liga.
Mina joined Nani on the sidelines on Wednesday after tests confirmed he was suffering from a calf problem.
Los Che have confirmed, meanwhile, that Nani, who was ruled out on Tuesday, will "visit a medical specialist to assess his recent injuries to try and reappear as soon as possible."
The Portugual international has been struggling with a thigh injury and has not played since being taken off in the first half of the 2-1 win over Real Madrid at the end of February.
Striker Rodrigo Moreno is also missing for Valencia, meaning on loan Barca forward Munir El Haddadi is once again likely to start against his former club.
Munir scored against Barca in October's game at Mestalla, which was settled via a last-minute Lionel Messi penalty.
Barca can ill-afford more dropped points against Valencia after losing to Deportivo La Coruna at the weekend.
They're two points behind La Liga leaders Madrid but have played a game more and face an improved Valencia side on Sunday.
Under Voro, their third manager of the season, they have won five of their last 10 league games, including impressive victories over Athletic Bilbao and Madrid.
They won in the league at Camp Nou last season, too, although they were hammered 7-0 there in Copa del Rey when Gary Neville was in charge.
