The match referee for England's Twenty20 series whitewash of Sri Lanka this week has tested positive for COVID-19.
Phil Whitticase returned the positive result following a PCR test administered on Friday at the Ageas Bowl in Southampton.
He will now observe a 10-day period of self-isolation from June 25 in accordance with the UK Government's protocol on quarantine, a statement from the England and Wales Cricket Board (ECB) said.
The ECB also confirmed seven other members from the match officials and anti-corruption unit teams were deemed to be close contacts, including five people who were due to officiate at England's first ODI match against Sri Lanka in Durham on Tuesday. They will also have to self-isolate for 10 days.
No members of the two teams were impacted, according to the ECB, which said alternative arrangements will be put in place to ensure Tuesday's ODI goes ahead as planned.
