England bowler Jofra Archer has been sent into self-isolation and ruled out of today's second Test against the West Indies after "a breach of the team's bio-secure protocols".
Both teams have been living, training and sleeping in two 'bubble' sites, at the Ageas Bowl and Emirates Old Trafford, adhering to strict health and safety procedures agreed by both boards, put in place due to the coronavirus pandemic.
Archer has now confessed to breaking those rules and has been removed from the team environment immediately.
Archer said: "I am extremely sorry for what I have done. I have put, not only myself, but the whole team and management in danger. I fully accept the consequences of my actions, and I want to sincerely apologise to everyone in the bio-secure bubble."
Archer, who had been retained for this week's game in Manchester while James Anderson and Mark Wood were rested, added: "I have put, not only myself, but the whole team and management in danger. I fully accept the consequences of my actions, and I want to sincerely apologise to everyone in the bio-secure bubble."
A statement from the England and Wales Cricket Board said: "Archer will now commence five days of isolation and will undergo two COVID-19 tests in this period, which have to test negative before his self-isolation period is lifted.
"The West Indies team have been made aware and are satisfied with the measures that have been imposed."
While it is not yet clear what Archer did to contravene the rules, it is understood the breach did not occur at Old Trafford, but in between the venues.
At one stage there were serious concerns that the entire English summer programme would be wiped out by Covid-19 - with chief executive Tom Harrison outlining that the worst-case estimates for that scenario involved a near £400million loss to the game.
The West Indies' willingness to travel and take part in the series was, therefore, a huge boost and involved much meticulous planning.
For an individual to have put the mutual trust at risk will, in the circumstances, be seen as a matter of utmost seriousness.
