Three people have tested positive for coronavirus at Cologne and will be placed into a 14-day quarantine, the Bundesliga club said, in a potential blow to hopes of restarting the German football season this month.

“Cologne had the entire team and coaching staff, along with the backroom staff, tested on Thursday for Covid-19. Three people tested positive, all are symptom free,” the club said in a statement on its website.

“After an assessment of the cases by the responsible health authorities, the three people who tested positive will go into a 14-day quarantine at home.”

The club said it would continue to train as part of plans to resume the campaign.
