If any party to the match has any reason to doubt whether a particular match of the competition can take place as scheduled (including but not limited to pitch, facility and infrastructure, safety and security, operational and/or organisational problems and/or weather conditions), they must notify the UEFA administration immediately. If the UEFA administration receives any such notification, or has any reason itself to believe that a match may not be able to be played as scheduled, it decides if any change will be made to the stadium, venue, date and/or kick-off time. Such a decision by the UEFA administration is final. If the stadium is changed, the costs of staging the match(es) concerned are borne by the host association.
The referee decides if a match which has started must be suspended. This decision is made after consultation with the UEFA match delegate and, when possible, the UEFA administration.
