Arsenal manager Mikel Arteta has tested positive for coronavirus, the Premier League club have announced.
The Gunners have closed their training ground and club staff who had recent contact with Arteta will now self-isolate.
The Premier League will hold "an emergency club meeting" on Friday to discuss future fixtures, BBC reported.
"This is really disappointing," Spaniard Arteta said. "I took the test after feeling poorly. I will be at work as soon as I'm allowed."
Arsenal expects a "significant number of people" will self-isolate, including the "full first-team squad".
The club were due to face Brighton in the Premier League at Amex Stadium on Saturday (15:00 GMT) but Brighton released a statement, shortly after confirmation of Arteta's positive test, announcing that the game had been called off.
