Championship leader Lewis Hamilton suffered his first retirement of the season after he went off the track at the Chinese Grand Prix.
The McLaren driver was running on worn-out intermediate tyres, with his right rear tyre delaminating fast.
Hamilton lost control of his car when trying to enter the pits, going off at the entry of the pitlane. He ended up stuck in the gravel and was unable to return to the track.
"The tyres were finished, and these things happen," Hamilton told ITV.
Hamilton, 12 points ahead of teammate Fernando Alonso before this race, needed to finish ahead of the Spaniard and Kimi Raikkonen to clinch the title.
His retirement left Raikkonen in the lead with Alonso in second, meaning the title battle is likely to go down to the wire.
"I'm sorry for the team, but I can still do it, don't worry," Hamilton added.
