Sam Curran has gone into self-isolation and has taken a Covid-19 test after he bowed out of England's lone warm-up match owing to illness.
Curran was unbeaten on 15 at the end of the first day of the intra-squad practice game before he experienced sickness and diarrhoea overnight.
The warm-up match is taking place at the Ageas Bowl, the venue of next week's first Test between the hosts and the touring West Indies.
In line with the medical protocols to ensure a bio-secure atmosphere, Curran remained secluded in his room at the on-site hotel accommodation.
He thus took no part in Thursday's cricket action and avoided any interaction with teammates.
"Sam Curran has had sickness and diarrhoea overnight," the England and Wales Cricket Board said in a statement.
"He is feeling better this afternoon, and has been self-isolating in his room at the Ageas Bowl.
"He will play no further part in the practice match. He has been monitored by the team doctor throughout and was tested for COVID-19 earlier today."
England have not yet named the squad for the first Test scheduled to commence on July 8. The home side is already without the services of permanent red-ball skipper Joe Root with Ben Stokes named the stand-in captain.
