Lewis Hamilton and Fernando Alonso were handed 20-second penalties following the Malaysian Grand Prix at Sepang.
The McLaren driver, who endured a difficult race and finished in seventh position, was handed the penalty for making more than one move to defend his position when fighting with Alonso.
Ferrari driver Alonso was given the penalty after he made contact with Hamilton during their fight, the Spaniard damaging his front wing and having to pit to replace it.
Both were given post-race drive-throughs, meaning 20 seconds added to their final times.
The penalty has dropped Hamilton to eighth, with Sauber's Kamui Kobayashi taking seventh.
Alonso keeps sixth place.
