The FA face an anxious wait to discover where England 's Nations League clash with Iceland will take place - following the Government's new travel ban on people visiting from Denmark.
The game at Wembley on November 18 is now in serious doubt due to restrictions relating to concerns over a new Covid-19 strain that has spread from minks to humans.
Iceland are due to face Denmark in Copenhagen 72-hours before facing the Three Lions.
FA bosses have written to the Government's DCMS committee seeking answers, but are not expected to hear back from them until later this week.
The FA are still hopeful the Danish squad will be granted 'exempt status' and be allowed to travel to London.
But if not, the FA will face the logistical nightmare of having to re-arrange the clash for a neutral venue, with Hungary, Greece, Poland and Cyprus being mooted as possible options.
Whatever happens, the game will still take place somewhere in Europe.
Elite sportspeople have been exempt from coronavirus-related travel restrictions since June.

Uefa's Covid-19 protocols state that international matches allow for a game to be rescheduled at a date fixed by Uefa, or to be played in a neutral venue if necessary decided by the host nation.
Under the new rules, UK citizens and visa holders can return from Denmark - but will have to isolate along with all members of their household for 14 days.
It means Danish stars who play in the Premier League might have to isolate for two weeks upon their return if they travel to the country for international duty.
This would affect the likes of Leicester goalkeeper Kasper Schmeichel, Everton's keeper Jonas Lossl, Chelsea defender Andreas Christensen, Southampton centre-back Jannik Vestergaard and Tottenham midfielder Pierre-Emile Hojbjerg, who are all in the squad.
Fifa rules outlined at the start of the pandemic allow clubs to withdraw players from international duty if there is a risk of coronavirus infection.
Liverpool are also due to play at Danish side FC Midtjylland on December 9 in the Champions League.
