Burnley captain Ben Mee has tested positive for Covid-19 and will miss Saturday's Premier League clash with Manchester City.
Clarets boss Sean Dyche said the 32-year-old defender was 'fine' and it was an isolated case, but it is not clear when Mee will be available again.
Dyche declined to reveal what percentage of his squad are vaccinated and he will continue to leave that decision up to individual players.
He said: 'Everyone's at liberty to decide what they wish to decide. I'm double vaccinated, all of my staff as far as I know are.
