21.01 As a rule, a player who is sent off the field of play is suspended for the next
match in a UEFA club competition. The Control and Disciplinary Body is
entitled to augment this punishment. For serious offences the punishment
can be extended to all UEFA competition categories.
21.02 In case of repeated cautions, a player is suspended for the next competition
match:
a) after two cautions in two different matches during the qualifying phase;
b) from the first match in the first round, after three cautions in three different
matches, as well as following any subsequent odd-numbered caution
(fifth, seventh, ninth, etc.).
21.03 Single yellow cards and pending suspensions are always carried forward
either to the next stage of the competition or to another club competition in
the current season.
21.04 Exceptionally, single cautions from the qualifying phase that have not
resulted in a suspension expire on completion of the qualifying phase in
question.
21.05 Cautions and pending yellow-card suspensions from club competition
matches expire at the end of the season.
