Players from Danish Super League clubs Brondby and Lyngby are in isolation after they met and hugged former Denmark international Thomas Kahlenberg, who has since tested positive for coronavirus, at a match last weekend.
Kahlenberg, who played 47 matches for Denmark between 2003 and 2014 and also played for clubs Auxerre and Wolfsburg before retiring in 2017, tested positive on Thursday and has been in quarantine.
Kahlenberg, who played for Denmark at the 2010 World Cup, was infected during a visit to Amsterdam.
Brondby, who beat Lyngby 1-0 last Sunday, said 13 employees had been put in isolation, including the general manager Ole Palma, defender Joel Kabongo and assistant coach Martin Retov.
Lyngby said three players, who were in physical contact with Kahlenberg on Sunday, had been put in isolation.
Both teams have league games this weekend. The Danish FA said that for now all matches will go ahead as planned this coming weekend, but that it is monitoring the situation.
