French league clubs Monaco and Lens both say one of their players has tested positive for the coronavirus.
Monaco did not name the player but says he is recovering and that the club has informed league officials.
Monaco is scheduled to play at home against Reims on Sunday in the opening weekend of the season.
Lens defender Jonathan Clauss has also tested positive for the virus. Lens coach Franck Haise says Clauss is showing no symptoms and is in isolation from the rest of the squad.
Newly-promoted Lens is also in action on Sunday. The club will travel south to play Nice.
