“Lewis tested negative for COVID-19 on Wednesday prior to completion of his self-isolation period in Bahrain,” Mercedes said in a statement.
“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 and will be able to take part in the race weekend,” added the team.
The FIA confirmed separately that Hamilton would be granted access to the paddock after testing negative in both Bahrain and Abu Dhabi.
While his return will be welcomed by fans, there will still be some disappointment for those who had hoped to see Russell get a second chance at victory after his impressive debut for the team a week ago.
The Mercedes-contracted youngster qualified on the front row, took the lead into the first corner and led for 59 laps before Mercedes botched his pitstop and a late puncture brought further misfortune.
Russell still finished ninth and with the fastest lap for his first points in Formula One.
