As a rule, a player or a team official sent off from the field of play and/or its immediate surrounds, including the technical area, is automatically suspended for the next match in a UEFA club competition (i.e. UEFA Champions League, UEFA Europa League or UEFA Super Cup). In case of serious offences, the UEFA Control, Ethics and Disciplinary Body is entitled to augment this punishment, including by extending it to other competitions.
In case of repeated cautions:
before the group stage, players and team officials are suspended for the next competition match after three cautions, as well as after the fifth and seventh caution;
from the first match in the group stage, players and team officials are suspended for the next competition match after three cautions, as well as following any subsequent odd-numbered caution (fifth, seventh, ninth, etc.).
Single yellow cards and pending suspensions are always carried forward either to the next stage of the competition or to the UEFA Europa League in the current season.
Exceptionally, all yellow cards and pending yellow-card suspensions expire on completion of the play-offs. They are not carried forward to the group stage. In addition, all yellow cards expire on completion of the quarter-finals. They are not carried forward to the semi-finals.
Cautions and pending yellow-card suspensions from the competition or the UEFA Europa League expire at the end of the season.
