Gaetano Berardi has received a club record eight red cards for Leeds United, although his last against Millwall was rescinded by the Football Association. Officially, Gaetano Berardi holds the joint-club record for most sendings off alongside Alan Smith with seven dismissals each.

The card system was experimented with at the 1970 World Cup in Mexico following the idea by English referee Ken Aston. It was introduced to the Football League by the Football Association six years later in 1976. In January 1981, the card system was abolished by the FA council because the FA believed that "demonstrative referees" were becoming a problem. The International Board reintroduced red and yellow cards at the start of the 1987/88 season.
The Premier League introduced red and yellow cards to managers and team officials for misconduct ahead of the 2019/20 season. Leeds' managerial sendings off have also recently been added to the records.
