Lots could be drawn if a Nations League match cannot go ahead due to the coronavirus pandemic and both or neither country is deemed responsible.
The executive committee of European football's governing body UEFA has set out what would happen in the event of matches in the competition – which starts in the forthcoming September international break – being affected by Covid-19.
It ruled that a match could go ahead in the event of players being placed into quarantine or self-isolation provided a national squad had a minimum of 13 players left to call on, including at least one goalkeeper.
If a country has fewer than 13 players available, efforts should be made to reschedule the match in the first instance but if not, UEFA’s control, ethics and disciplinary body (CEDB) will determine where responsibility for the cancelled fixture lies.
If one country is deemed responsible, it will forfeit the match. If neither or both are determined to be responsible, lots will be drawn to decide whether the match should be awarded as a 1-0 home win, a goalless draw or a 1-0 away win.
The same principles will apply to European Under-21 Championship qualifiers and Women’s Euro qualifiers, UEFA said.
The Republic of Ireland begin their Nations League campaign this week with an away date against Bulgaria on Thursday, in what will be Stephen Kenny's first game in charge.
