The Copa del Rey matches involving Valencia and Levante have been postponed following floods that killed more than 60 people and caused havoc in southern Spain.
Other sporting events were also affected by Tuesday's flash floods that swept away cars, turned village streets into rivers and disrupted rail lines and highways in the worst natural disaster to hit the European nation in recent memory.
Clubs, soccer stars and other athletes - including Vinicius Junior, Luka Modric, Sergio Ramos, Diego Simeone and Thibaut Courtois - were quick to post messages of support on social media.
"Real Madrid is deeply saddened and expresses its solidarity with all the people affected by this catastrophe, to whom it conveys all its full support and sympathy," the club said.
Both Madrid and Barcelona held a moment of silence before their training sessions on Wednesday.
