Championship leader Lando Norris and his McLaren teammate Oscar Piastri were disqualified on Sunday from the Las Vegas Grand Prix for technical infringements.
The skid blocks on both cars were found after the race to be less than the minimum depth.
Norris had finished second in the race behind Red Bull's title-chasing Max Verstappen with Piastri in fourth.
The disqualification means that Norris is now 24 points ahead of both Piastri and Verstappen going into the penultimate race of the season in Qatar next weekend, which includes a sprint.
With a maximum of 58 points available in the final two grands prix, Norris can win the title in Qatar if he earns two more points than both Verstappen and Piastri over the course of the weekend.
