Marseille's Ligue 1 season opener against Saint-Etienne has been postponed after the club confirmed three positive coronavirus tests.
The Ligue 1 club revealed on Sunday that three individuals within their "professional workforce" had been detected as potentially having Covid-19.
Their communication at the time indicated the club were seeking confirmation regarding these cases and follow-up tests on Monday all came back positive.
These results take the French outfit's total positive cases up to four in the past week, with the club subsequently announcing the transfer of all relevant information to the LFP.
Marseille's administration team delivered a message to supporters via Twitter on Tuesday, which reads: "Following the tests carried out on Monday, no new cases of Covid-19 were revealed, but Sunday's 3 suspected cases have been confirmed."
Marseille were due to kick off the 2020-21 Ligue 1 campaign on Friday at home to Saint-Etienne – but French football authorities have now confirmed that the fixture has been called off.
An official statement released by Ligue 1 reads: "In view of the medical results transmitted by Olympique de Marseille on Tuesday, August 18, the national Covid commission indicates to the LFP Competitions Commission that the virus is circulating within the Marseille club and proposes the postponement of the match."
The match will now be rescheduled to take place on either Wednesday, September 16 or Thursday, September 17, subject to further medical evaluations.
Friday's contest would have been the first Ligue 1 fixture since early March, when French authorities suspended action due to the coronavirus – with the competition then officially ended prematurely on April 28.
PSG were subsequently crowned champions for a third successive year, while Marseille secured a runners-up spot and automatic Champions League qualification.
