No substitute driver able to take Mazepin's place at this stage of the weekend so one fewer car than normal raced on Sunday

Haas driver Nikita Mazepin has tested positive for Covid-19, causing him to miss Sunday's season-ending Abu Dhabi GP.
It means that only 19 drivers took part in the race. Substitutes are only able to compete if they have taken part in at least one practice session.
Mazepin, the 22-year-old Russian, had driven in all sessions ahead of the race.
Mick Schumacher was therefore the sole Haas car on Sunday afternoon's grid when the race started.
Writing on Twitter, Mazepin posted:
Ahead of Sunday's event, F1 said that all Mazepin's contacts have been declared and that there would be no wider impact on the running of the race.
