England's Test squad has been cleared to begin training ahead of next week's series opener with Sri Lanka after being retested for coronavirus.
Joe Root's travelling party had been isolating in their hotel rooms after all-rounder Moeen Ali returned a positive result from PCR tests taken upon arrival at the airport in Hambantota on Sunday.
Moeen will continue to observe a 10-day quarantine period, while team-mate Chris Woakes will isolate for a minimum of seven days after being deemed a possible close contact.
However, the latest round of results show Moeen to be the only positive case and the rest of the squad can begin restricted training on Wednesday.
"All PCR tests from yesterday are negative, except for Moeen Ali, and we can start controlled training this afternoon," an ECB spokesman said.
"Close contact Chris Woakes tested negative but will continue to isolate in his room."
England's two-match series with Sri Lanka gets under way in Galle on January 14.
