Last year, the ICC approved “like for like” substitutes across all formats of international cricket to replace concussed players during matches and Elworthy said the same rule would have to be applied for Covid-19 substitutes.
“Covid replacements are certainly something that the ICC are discussing,” Elworthy told Sky Sports.
“I’ve seen communication about that and it’s certainly something we hope would be allowed - specifically for Test matches, not necessarily ODIs (one-day internationals) or T20s (Twenty20).
“That replacement would have to be a ‘like for like’ player... Our on-site Covid medical practitioner and Public Health England would be informed immediately and that player would then be put into isolation for a period of time.”
England are set to host the West Indies in a three-Test series next month, with the visitors flying in a 14-man squad plus 11 reserves who will train and quarantine together before the first Test scheduled for July 8 in Southampton.
“With the testing protocols of getting those players into that (bio-secure) bubble first, you would hope that wouldn’t be a scenario we’d have to deal with,” Elworthy added.
“But clearly it’s something we are planning for.”
The behind-closed doors matches will take places at Hampshire’s Ageas Bowl on July 8, followed by two Tests at Old Trafford beginning on July 16 and July 24 respectively.
The West Indies team, which agreed in principle to take part in the series last week, is scheduled to travel to England on June 9, and will be based at Old Trafford for quarantine and training.
