The cup match against Parla Escuela was supposed to be played last week, but was one of several Valencia matches that were postponed after the disaster in the region. Over 200 people have died in the massive floods.
The plan was to play the match instead on Wednesday, but Valencia asked the country's football association to postpone it further.
"During this difficult period, the club believes that all focus, all support, and all efforts should be directed towards helping those affected. Football can take a step back.", writes Valencia on its website.
Shortly afterwards, the Spanish football association decided to postpone the cup match against Parla Escuela once again.
The league match against Real Madrid, which was supposed to be played on Saturday, has also been postponed.
Several coaches and players in La Liga have argued that all matches in the men's top league should have been cancelled last weekend. Now, only Valencia's and Villarreal's (also from the affected region) home matches were postponed.
