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).
