If one or more players or officials of a team test positive for COVID-19 in the tests required by the UEFA Return to Play Protocol, the match(es) will take place as scheduled unless the national authorities of the host association/host country or, in case of a neutral host country, the authority of the country where the match will take place require a large group of players or the entire team to go into quarantine. If at least 7 players registered on the players list (including at least one goalkeeper) are available, the match(es) must go ahead on the scheduled date(s). If less than 7 players registered on the players list or no registered goalkeeper are available, UEFA may allow a rescheduling of the match, if the relevant national authority seeks new tests to allow a sufficient number of players (at least 7 including at least one goalkeeper) to participate in the match. Alternatively, 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 the relevant competition and (ii) are tested negative in accordance with the UEFA Return to Play Protocol. If it is not possible to reschedule the match(es) within the final deadline set out in Annex B.4.1, the team that cannot play the match(es) will be held responsible for the match 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 it 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.
