Red Bull pair Daniil Kvyat and Daniel Ricciardo have both been given a 10-place grid penalty ahead of the Austrian Grand Prix.
Both Red Bull cars were fitted with their fifth engines of the season ahead of practice, which automatically triggers the penalties.
Both drivers will need to qualify in the top 10 in order to avoid further time penalties. Kvyat was sixth-fastest in first practice, with Ricciardo finishing in seventh.
Ricciardo is currently seventh in the Formula 1 standings, with Kvyat in eighth.
