Football fans have been asked to end so-called 'tragedy chanting' ahead of Leeds United's game with Liverpool on Monday evening.
Flowers are due to be presented pre-match to remember the 97 Liverpool fans who died in the Hillsborough disaster.
The Leeds United Supporters' Trust said club CEOs would swap pennants in front of a plaque for killed Leeds fans Christopher Loftus and Kevin Speight.
The trust asked fans to consider the impact of chants on affected families.
"We remind fans about [Christopher and Kevin's] families' request to put an end to tragedy chanting and to understand and respect the impact it has on those affected," they said in a Tweet.
