Should a group of players of a team be placed into mandatory quarantine or self-isolation following positive COVID-19 tests and in line with the measures set out in the UEFA Return to Play Protocol (and/or following a decision of a competent national/local authority), the match must go ahead on the scheduled date if at least 13 players registered on the 40 players list (including at least one goalkeeper) are available. If less than 13 players registered on the 40 players list, or no registered goalkeeper, are available, UEFA may allow a rescheduling of the match to allow a sufficient number of players (at least 13 including at least one goalkeeper) to participate in the match. In this case, the club may field players who have not been registered with UEFA within the deadlines stipulated in the present regulations, provided that these players (i) are duly registered with their national association as playing for the club concerned in accordance with the association’s own rules and those of FIFA, (ii) comply with the age limit as established in the competition regulations, and (iii) comply with the requirements of the UEFA Return to Play Protocol. If it is not possible to reschedule the match within the final deadline set out in, the club that cannot play the match will be held responsible for the match not taking place and the match will be declared by the UEFA Control, Ethics and Disciplinary Body to be forfeited by the club, which will be considered to have lost it by 3-0. Moreover, the UEFA Control, Ethics and Disciplinary Body may take further disciplinary measures if the circumstances so justify.
If any member of the appointed referee team for a match tests positive for COVID-19, UEFA may exceptionally appoint replacement match officials who (i) may be of the same nationality as one of the clubs, and/or (ii) may not be on the FIFA list.
