England players Mason Mount and Ben Chilwell have been told to isolate until the end of Monday.
They've been confirmed as close contacts of Scotland's Billy Gilmour - who tested positive for coronavirus in the days following Friday's goalless draw at Euro 2020.
Both players will miss tonight's Group D match with the Czech Republic and will train alone - but if England finish top of their group, they will be available for their last-16 game next Tuesday.
Also this evening, Scotland will look to progress into the knockout stage.
They need to beat Croatia at Hampden Park to advance.
Both games kick off at 8pm
