The Premier League will hold an emergency meeting on Friday, with the Arsenal and Chelsea first-team squads in self-isolation after positive coronavirus tests for Gunners manager Mikel Arteta and Chelsea winger Callum Hudson-Odoi.

This weekend’s programme is now in jeopardy after Arsenal confirmed Arteta had contracted Covid-19 before Chelsea reported Hudson-Odoi’s case hours later.

The Gunners’ trip to Brighton on Saturday was immediately postponed and further games appear certain to follow, while in golf, the US PGA on Thursday called off the Players Championship at Sawgrass after the first round, as well as its scheduled tournaments for the next three weeks.

The Premier League could follow the NBA in suspending its season, with US basketball officials clarifying on Thursday the league will be halted for at least 30 days.

In tennis the ATP Tour has announced a six-week suspension of activity. Aside from the men’s Players Championship abandonment the ANA Inspiration – the first women’s major of the year – is among five LPGA tournaments cancelled.

Major League Soccer, Major League Baseball, the NBA and NHL have all been paused in the United States. Other FIBA, NCAA and EuroLeague basketball games are also affected.

Other positive tests for coronavirus include former Southampton forward Manolo Gabbiadini and Colombian cyclist Fernando Gaviria.
