Red Bull will not take part in tomorrow's qualifying for the Abu Dhabi Grand Prix after a breach of car regulations.
Daniel Ricciardo and Sebastian Vettel finished Saturday's qualifying in fifth and sixth respectively, but were both called before the stewards after the FIA technical delegate decided that the front wings of their cars were illegal.
A statement from the FIA said: "When checking the front wing of car numbers one and three, it was found that the front wing flags were designed to flex under aerodynamic load.
"In my opinion, this is not in compliance with article 3.15 of the Formula 1 technical regulations. Therefore, I am referring this matter to the stewards for their consideration."
Ricciardo and Vettel's exclusion was confirmed at 9.26pm local time.
