Lewis Hamilton has tested positive for Covid-19.
He will miss this weekend’s F1 Rolex Sakhir Grand Prix.
“The FIA, Formula 1 and Mercedes-AMG Petronas F1 Team can today confirm that during mandatory pre-race PCR testing for the Sakhir Grand Prix, Lewis Hamilton has tested positive for COVID-19,” said a FIA statement.
“In accordance with Covid-19 protocols and public health authority guidelines in Bahrain he is now isolating.
“All contacts have been declared.
“The procedures set out by the FIA and Formula 1 will ensure no wider impact on this weekend’s event.”
Mercedes have yet to name Hamilton's replacement.
"Apart from mild symptoms, he is otherwise fit and well, and the entire team sends him its very best wishes for a swift recovery," Mercedes said in a statement.
Hamilton needs a negative test before being allowed to return to the paddock, and therefore remains a doubt for the final race of the season in Abu Dhabi.
The Briton is the third F1 driver to test positive for Covid-19 this season, following Sergio Perez at Silverstone and Lance Stroll in Germany.
