Stoke manager Michael O'Neill has tested positive for Covid-19 as a friendly between the Potters and Manchester United was called off.
The sides were due to take part in a bounce game to prepare for restarts in the English Premier League and Championship.
But the game was cancelled just before kick-off as the former Northern Ireland manager tested positive in a release of Monday's results.
Social distancing measures mean that Stoke players did not come into contact with the Manchester United squad and O'Neill is said to be asymptomatic.
A Stoke statement read: " Stoke City can confirm that manager Michael O'Neill has tested positive for the Covid-19 virus following the latest round of testing on Monday (June 8).
"O'Neill had tested negative in the previous five rounds of testing.
"He will now follow the relevant guidance and undergo a period of isolation, whilst continuing to be in regular virtual contact with his coaching staff and players.
"Assistant manager Billy McKinlay will take charge of training as the Potters prepare for their game against Reading on June 20.
"The club will be making no further comment on this matter."
