Leicester have moved to close their training ground for 48 hours from Thursday after Covid-19 cases in the squad forced the clash with Tottenham to be postponed.
With calls growing for the Premier League season to be paused amid outbreaks across the competition, the Foxes' match at Everton on Sunday now appears in doubt.
Neither Leicester nor Spurs had wanted to play the game due to the rapid spread of coronavirus in their squads and 'further positive tests' left manager Brendan Rodgers unable to field a team for Thursday.
