The squad have been in Bilbao for the last eight of the competition, with goals from Marie-Antoinette Katoto and Signe Bruun allowing them to beat Arsenal 2-1 on Saturday evening to secure a place in the final four.
However, less than three hours before their semi-final was due to kick-off, PSG announced that in the latest round of testing, conducted on Tuesday 25 August, one of the members of their squad had tested positive for coronavirus.
“Covid-19 tests carried out on August 25 in Bilbao revealed that one of the Paris Saint-Germain players is positive for the virus,” the statement said.
“The player is currently isolated from the squad and will not take part in tonight’s meeting [with Lyon], in accordance with UEFA protocol.”
Earlier this month, there were concerns over whether Atletico Madrid‘s quarter-final tie with Barcelona in this competition would go ahead, after four new positive tests among the Atleti squad and coaching staff were announced just 10 days before the game.
The Spanish club, who had to cancel a friendly match just the week before due to another positive test, suspended all training as a result.
Atleti returned to training six days later, just four days before that clash with Barcelona, which they narrowly lost 1-0 after an 80th-minute goal from Kheira Hamraoui.
The German side triumphed behind a goal from Fridolina Rolfo, who sent Wolfsburg right through to the club’s fifth Women’s Champions League final.
Lyon are the current holders in the competition, having been crowned champions of European for the last four years running.
They got the better of their domestic rivals PSG in both the league and the cup in France this year too, beating their biggest rivals on penalties in the final of the latter at the beginning of August.
