The English Premier League will convene an emergency meeting on Friday to discuss future fixtures, following Arsenal manager Mikel Arteta contracting the coronavirus.
"In light of Arsenal's announcement tonight confirming that their first team coach Mikel Arteta has tested positive for COVID-19, the Premier League will convene an emergency club meeting tomorrow morning," the Premier League said in a statement.
Earlier Arsenal released a statement revealing Spanish coach Arteta had picked up the virus and, as a result, their entire squad would now be quarantined.
"Our London Colney training centre has been closed after head coach Mikel Arteta received a positive Covid-19 result this evening," a club statement read.
"Arsenal personnel who had recent close contact with Mikel will now self-isolate in line with Government health guidelines.
"We expect this to be a significant number of people from Colney, including the full first-team squad and coaching staff."
The Gunners were due to travel to Brighton on Saturday and their midweek match with Manchester City was also postponed as some of their players had come into contact with the owner of Olympiacos, who tested positive for the virus.
Chelsea are also affected with the club confirming winger Callum Hudson-Odoi has tested positive for the virus.
The 19-year-old displayed cold symptoms on Monday morning and has stayed away from the club since then. His test result was returned on Thursday night.
"Chelsea personnel who had recent close contact with the player in the men's team building will now self-isolate in line with Government health guidelines," the club said.
"These will include initially the full men's team squad, coaching staff and a number of backroom staff."
The Blues have also closed two buildings at their training facility.
Earlier, defending Premier League champions Manchester City confirmed one of their players is in self-isolation after a family member was taken to hospital with symptoms of a respiratory illness.
A City statement said the family member had undergone tests at hospital, including for the coronavirus, and the player would continue to self isolate until the results were known.
The club did not say which player was self-isolating, but British media reported it was French defender Benjamin Mendy.
City's Champions League last-16 second leg against Real Madrid set for next Tuesday has been postponed after Real players were ordered into quarantine when a member of the club's basketball team tested positive for coronavirus.
The Premier League earlier issued a statement saying matches would go ahead at the weekend, but that is looking increasingly unlikely now.
