Lewis Hamilton has been slapped with a five-place grid penalty after Mercedes changed his gearbox.
Final practice did not end on the best of notes for Hamilton as the Mercedes driver suffered a rear-left tyre failure as the chequered flag was waved.
This damaged his W04's suspension resulting in Hamilton, who had been fifth quickest - 0.208s off the pace - limping back into the pits.
Mercedes were forced to repair the left corner of the car while the gearbox will also have to be replaced.
As such Hamilton will incur a five-place grid penalty for Sunday's 57-lap Bahrain Grand Prix.
