England’s Ben Chilwell and Mason Mount are isolating after coming into contact with Scotland’s Billy Gilmour during Friday’s Euro 2020 match between the two countries.
Gilmour is also isolating after testing positive for COVID-19. All three play their club football with Chelsea.
England manager Gareth Southgate said there was “quite a doubt” that Chilwell and Mount would be available to play against Czech Republic at Wembley tomorrow.

Speaking in a news conference early on Monday evening, he added that the next 12 hours would be critical.
Isolation is being imposed on the midfielder and left back as a “precaution in consultation with Public Health England”, the FA said.
Southgate said PCR tests among his squad on Sunday had been followed by lateral flow ones on Monday, for a “belt and braces approach”.
None had tested positive, the FA said.
The Scottish FA said Gilmour will self-isolate for 10 days following the positive test and now misses Scotland‘s match against Croatia at Hampden Park in Glasgow on Tuesday.
The FA said in a statement: “As a precaution at this time and in consultation with Public Health England [PHE], Ben Chilwell and Mason Mount are isolating after interaction with Scotland player Billy Gilmour at Friday’s match.
“The pair will be kept away from the rest of the England players and wider support team, pending further discussions with PHE.”
Gilmour won the man of the match award in Scotland’s draw against England at Wembley on Friday – his full international debut.
Sky Sports News said it understands that no other Scotland players have been affected or identified as close contacts, meaning the remainder of the squad will be available for the Croatia match.
The Scots must win to progress to the knockout stages, in what is their first major tournament in 25 years.
