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(es) will take place as scheduled if at least 7 players registered on the players list (including at least one goalkeeper) are available. If less than 7 players registered on the players list or no registered goalkeeper are available, UEFA may allow a rescheduling of the match(es) (i.e. subject to viable rescheduling options being available) to allow a sufficient number of players (at least 7 players including at least one goalkeeper) to participate in the match(es). In this case, the team may field players who have not been registered with UEFA within the deadlines stipulated in the present regulations, provided that these players (i) are eligible to play in accordance with Article 36 of the competition regulations and (ii) that they fulfil the requirements of the UEFA Return to Play Protocol. Any additional player, included in the list of 25 players, called up to meet at least the minimum of 7 players requires that an equivalent number of quarantined players are definitively withdrawn from the 14 players list. If it is not possible to reschedule the match(es) within the final deadlines set out in Annex B.2.1, the team that cannot play the match(es) will be held responsible for the match(es) not taking place and the match(es) will be declared by the UEFA Control, Ethics and Disciplinary Body to be forfeited by the team, which will be considered to have lost them by 5-0. 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 teams, and/or (ii) may not be on the FIFA list.
