As a rule, a player or team official sent off by the referee is automatically suspended for the next match in a UEFA club competition (i.e. UEFA Champions League, UEFA Europa League, UEFA Conference League or UEFA Super Cup). In the event of a serious offence, the UEFA disciplinary bodies are entitled to augment this punishment, including by extending it to other competitions.
Single yellow cards are cancelled at the end of the match and are not carried forward to another UEFA club competition.
