Denmark's Women's Super League players are waiting to learn whether they will be allowed to travel for 1 December's home international against Italy.
Travel from Denmark to England has been restricted amid concerns about mink.
Earlier in November, the UK government agreed to an exemption to allow players to travel from the UK to Copenhagen and back, without needing to self-isolate.
That exemption was understood to expire on 26 November and it is unclear if it will be extended for 1 December's game.
The Danish women's national side are taking on the Italians in the city of Viborg, which is more than 150 miles from the capital of Copenhagen.
Danish and English football officials have asked the UK government for the exemption to be extended to allow the four WSL-based members of their national team to compete.
They are Chelsea's Pernille Harder, Everton's Nicoline Sorensen and Rikke Sevecke and Aston Villa's Stine Larsen.
Without an exemption from the government, the players and anybody else in their household would be required to self-isolate for 14 days after their return to England from Denmark.
That could see them have to miss WSL matches on the weekends of 5-6 December and 12-13 December, or miss Denmark's game against Italy instead.
The Danes have already qualified for the Women's European Championships, but Italy - who are second in their group - could need a result from 1 December's qualifier to reach the finals automatically.
There had been fears that the restrictions on travel between Denmark and England would see November's men's international game between Iceland and England postponed, because it was taking place three days after Iceland faced Denmark in Copenhagen.
But the government allowed a limited exemption for a small number of Danish and Icelandic national football players to travel from the UK to Copenhagen and back, without the need to self-isolate.
That meant Denmark's England-based men's international players could also play in their November fixtures too.
Representatives from the English Football Association are understood to have asked the government to grant the same exemption for Denmark's women's players, who hope to travel to their training camp on Wednesday.
The BBC has contacted the Department for Transport for a response.
