"Our thoughts remain with the families of Emiliano and David Ibbotson", said a message on Cardiff's club Twitter account shortly before kick-off.
It was Cardiff's first match since Emiliano Sala's body was recovered from an underwater wreckage in the English Channel - before being formally identified by the Dorset coroner.
French striker Kylian Mbappe has donated $35,000 to a fund to help the search for David Ibbotson, the pilot whose body has still not been found after the plane he was flying crashed with footballer Emiliano Sala on board.
"As a family, we are relying on the kindness of the good-hearted people", they continued.
Fans took to social media to slam the two men.
Investigators recovered the body on Wednesday and transported it to the southern English coast.
The page has a fundraising target of £300,000.
An initial search for the missing 28-year-old and Mr Ibbotson was called off on January 24 but, following calls for it to continue from the likes of Lionel Messi and Diego Maradona, a private operation funded by online donations was launched.
Of course, we would like to extend our deepest and most honest condolences to the families of both Emiliano Sala and David Ibbotson as they navigate these very hard times.
The light aircraft was en route to Cardiff when it crashed two days after Argentine striker Sala's £15m transfer was announced.
"We cannot bear the thought of him being alone, we need him home so that we are able to lay him to rest".
"The club will be taking an extremely firm stance against anyone involved and intends to ban those supporters identified".
Midfielder Aron Gunnarsson said: 'Sala's death brought everyone together, the performances and the fans and the lads and everyone around the club have been awesome at this hard time.
