Mercedes driver Valtteri Bottas has joined title leader Max Verstappen and Ferrari’s Carlos Sainz in being placed under investigation in Qatar.
AlphaTauri driver Pierre Gasly stopped off-line on the pit straight after sustaining front wing and front-right tyre damage when he ran heavily over the Turn 15 exit kerb.
Bottas, following behind on track, drove past the scene and has now been summoned over allegedly failing to adhere to a single-waved yellow flag.
Sainz is under investigation for the same offence while Verstappen is under investigation for allegedly failing to adhere to double-waved yellow flags.
Bottas must meet the stewards at 13:45 on Sunday, with Verstappen’s meeting scheduled for 13:00 and Sainz for 13:30.
In the event of Verstappen and Bottas receiving grid penalties then it would promote Gasly, who qualified fourth, onto the front row of the grid.
