The Gunners have been hit by an outbreak of the virus which has also seen Willian and Alex Runarsson test positive
Arsenal have confirmed that Pierre-Emerick Aubameyang and Alexandre Lacazette were among four positive Covid-19 cases before their Premier League opener last week.
Both men missed Arsenal's 1-0 defeat at Brentford on August 13 due to an at the time unspecified illness, along with backup goalkeeper Alex Runarsson.
The Gunners have now revealed that all three players were laid low with coronavirus, but Aubameyang will be available for their next fixture against Chelsea on Sunday after posting a negative test during the club's latest round of medical checks.
