Scotland’s qualification hopes have been hit on the eve of their must-win Euro 2020 showdown with Croatia after Billy Gilmour returned a positive coronavirus test.

The Chelsea midfielder impressed in his first Scotland start on Friday as he helped the team earn a goalless draw with England at Wembley.

That result left Steve Clarke’s side still in with a shot at reaching the knockout stages.

But Scotland have now received a major blow ahead of facing Zlatko Dalic’s team at Hampden, with the Scottish Football Association announcing the 20-year-old Champions League winner will have to quarantine for the next 10 days.

Gilmour’s positive test is the second to hit the Scotland camp since the squad met up earlier this month.

Sheffield United midfielder John Fleck sat out both of the Scots’ warm-up fixtures against Holland and Luxembourg after contracting the virus.

Another six players missed the 2-2 draw with the Dutch as a precaution, although they were not formally designated close contacts of Fleck.

Clarke is due to hold a press conference on Monday at 5.45pm.
