“Lewis tested negative for Covid-19 on Wednesday prior to completion of his self-isolation period in Bahrain. This enabled him to travel to Abu Dhabi on Thursday afternoon and he tested negative on arrival.
“Lewis has therefore completed the protocols required by the FIA for his entry to the paddock tomorrow [Friday] and will be able to take part in the race weekend.
“George Russell will return to Williams Racing for the final event of the 2020 season.”
Hamilton first reported Covid symptoms the day after his Bahrain Grand Prix win and a positive test prevented him from racing in the second Bahrain race where Russell made an impressive debut.
His participation in the Abu Dhabi race remained unknown this morning, so Russell took on Mercedes media duties today.
