England head coach Chris Silverwood will miss the fourth Ashes test in Sydney next week after a family member tested positive for COVID-19 and he must isolate for 10 days, the England and Wales Cricket Board said in a statement on Wednesday.
The fourth Test is due to start next Tuesday with Australia having already retained the Ashes, leading the series 3-0 with two matches to play.
"Following the latest round of PCR tests administered to the England men's touring party on Wednesday 29 December, one family member has tested positive," the ECB statement read.
