Jenson Button has been hit with a penalty for his accident with Pastor Maldonado during the Chinese Grand Prix.
The Briton and the Venezuelan were involved in an intense battle for 12th position when the McLaren driver crashed into the back of the Lotus at the end of the straight near the end of the race.
Maldonado was sent into a spin and later retired, while Button damaged his front wing but could continue to finish in 13th.
The incident was investigated by the stewards, who deemed Button was at fault.
The former world champion has been handed a five-second time penalty and two penalty points.
"The driver of car 22 admitted that he had made a mistake and had caused a collision with car 13 in Turn 1," said the stewards.
The penalty drops Button from 13th to 14th.
Button admits blame
"There was room on the inside," said Button, who apologised to his team on the in-lap. "An incident you never want to happen... a misjudgment I guess."
Maldonado said: "I was not expecting the contact. We were having a good fight but then I think he lost completely his braking point. I think he did a mistake."
Manor's Roberto Merhi was also penalised for failing to stay above the required time set by the FIA ECU during the deployment of the safety car.
The Spaniard was also handed a five-second penalty and two penalty points. He finished in 16th and last.
