Both players go ” isolate and train individually ”in private areas of St George’s Park training base in England until June 28, the FA said in a statement.
This means the pair will miss tonight’s Euro 2020 clash with the Czech Republic – and the decision was made in consultation with Public Health England.
The entire England squad and staff underwent lateral flow testing on Monday and all were negative again, as was the case with UEFA’s pre-match PCR testing on Sunday.
Further tests will be carried out as appropriate, the FA said.
Gilmour, who won the Man of the Match award for Scotland in the Group D second game against England, tested positive for COVID on Monday after Friday’s 0-0 draw.
In a statement, the Scottish FA said Gilmour – who plays club football for Chelsea – will self-isolate for 10 days after testing positive and miss ScotlandThird game against Croatia at Hampden Park in Glasgow tonight.
Mount and Chilwell hugged and spoke to Gilmour on the pitch and also reportedly spent 25 minutes with their Chelsea teammate in the tunnel afterward.
The pair could potentially miss England’s first knockout fixture for Euro 2020 depending on the outcome of tonight’s last Group D games.
If England are at the top of the group, they will face the second team in Group F (Portugal, France, Germany, Hungary) at Wembley next Tuesday.
But if Gareth Southgate’s team are finalists in Group D, they will face the finalists in Group E (Spain, Sweden, Poland, Slovakia) next Monday, which means Mount and Chilwell will not be available.
If England finish among the top four teams in third place, a situation which would force them to lose to the Czech Republic and Scotland to beat Croatia by a significant margin, they will face either the Group C winners or of group B on Sunday, or the winners of group E on Tuesday.
