England coach Chris Silverwood will miss the fourth Ashes Test after a family member of the touring party tested positive for coronavirus.

Silverwood's position has come under question after England's dismal form in Australia, with the hosts having already retained the urn by racing into a 3-0 series lead.

Defeats in Brisbane and Adelaide were followed by a capitulation in Melbourne this week, with the third Test not even lasting three days.

Silverwood will be unable to be in attendance for the fourth match of the Tour in Sydney, as England desperately search for a result in order to avoid a whitewash.

A family member who travelled to Australia has tested positive for COVID-19 in the latest round of PCR tests administered to the touring party, the England and Wales Cricket Board (ECB) confirmed.

Silverwood will therefore have to isolate for 10 days, along with his family, in Melbourne. Another round of PCR tests will take place on Thursday.

The fourth Test is due to start at Sydney Cricket Ground on January 5, with the series finishing in Hobart after coronavirus regulations in Western Australia meant Perth was unable to host the final match.
