Lewis Hamilton will serve a 10-place grid penalty for Sunday's Turkish Grand Prix.
The seven-time world champion has been forced to take on a new engine – his fourth of the year, one more than is permitted.
However, Hamilton will avoid starting from the back as he is changing only the internal combustion engine and not a full power unit.
And there was at least some early good news for the British driver on Friday as he completed a practice double on a dominant day for the seven-time world champion in Turkey.
The Briton ended the opening session on top - four tenths faster than Drivers’ Championship rival Max Verstappen - before setting the quickest time in the afternoon running.
The Mercedes driver finished 0.166 seconds clear of Ferrari’s Charles Leclerc with Valtteri Bottas third in the other Mercedes.
Verstappen was fifth in the day’s concluding running, 0.635 sec adrift of his championship rival.
Hamilton will hope to come through the field like the Dutchman did at the last race in Russia, where the Red Bull driver served his own grid penalty for taking on a fourth engine.
Hamilton leads Verstappen by two points with seven races of a fiercely contested season remaining.
Ferrari's Carlos Sainz will also start Sunday's race from the rear with a new power unit.
