Paris Saint-Germain have confirmed three players have tested positive for COVID-19 ahead of their return to Ligue 1 action next week.
The 2019-20 Champions League finalists are due to begin their domestic title defence at Lens on September 10, with that fixture pushed back at PSG's request.
However, a trio of players have contracted coronavirus ahead of that match, which will likely be postponed should a fourth positive test be returned.
A PSG statement on Wednesday read: "Three PSG players are confirmed positive after a Sars CoV2 test and have undergone the appropriate health protocols.
"All players and staff will continue to be tested over the next few days."
Both ESPN and L'Equipe are reporting that one of those players that tested positive is Neymar, who has been in Ibiza on holiday in recent days.
Thomas Tuchel's men were crowned Ligue 1 champions on a points-per-game basis after the 2019-20 season was abandoned in April because of the coronavirus pandemic.
They went on to win both domestic cups in the space of a week but were denied an historic quadruple after losing 1-0 to Bayern Munich in the Champions League final on August 23.
