After players who tested positive for Covid-19 developed lung lesions, French side Stade Francais cancelled its upcoming pre-season game.
The club was scheduled to face rivals Toulon before the season begins on September 5.
Up to 25 players in the team had tested positive for the virus according to French publication L’Equipe.
"In light of the mandatory medical examinations for all players who have been diagnosed positive with the RT-PCR test for Covid-19, it appears that some of them are carriers of lung lesions due to the virus,” read a club statement.
“These lesions require a period of complete rest estimated for the moment at a minimum of one week and which will be added to the fortnight already observed. Other reviews are currently underway.
“In addition, the input of the medical commission of the National Rugby League for an advisory opinion resulted, for obvious health reasons, in the cancellation of the friendly match against RC Toulon scheduled for August 27.
“Once again, the club would like to thank all those who have shown their support during these last days.”
