Several Chelsea players test positive for COVID-19: reports

Several Chelsea players have not returned for pre-season training after testing positive for COVID-19, according to reports in British media.

The reports did not name the players and Chelsea did not immediately respond to a Reuters request for comment.

Players who test positive have to self isolate for 10 days and return a negative coronavirus test before they can take part in training.

Sheffield United, Brighton & Hove Albion and West Ham United were among the other Premier League clubs to report positive COVID-19 cases in recent weeks, the Times said.

Frank Lampard's men, who finished fourth last season, kick off their campaign against Brighton on September 14.
