Nick Heidfeld has been handed a three-place grid penalty for the Chinese Grand Prix after the race stewards deemed he had impeded David Coulthard in qualifying.
Coulthard was furious after Q1 when Heidfeld slowed him down as the pair battled to get through to the second part of qualifying.
Afterwards the Red Bull Racing driver said: "He would have known he was in the top ten already, so for me it was very unsportsmanlike behaviour, as all he did was screw up my last flying lap - there wasn't any intention of him doing a quicker time."
The stewards took more than three hours to decide that Heidfeld had been guilty, and the penalty moves the German down to ninth on the grid.
"I have expressed my opinion about the incident. Now I will try tomorrow to do the best I can from P9," said Heidfeld.
