Alexander Sims has been excluded from the first GP3 race at the Hungaroring, handing the championship lead to race winner Valtteri Bottas.
Bottas initially moved up to second in the points with his victory, while Sims retained the lead in the standings by coming home fourth.
However, the Briton's Status Grand Prix car was excluded from the race following scrutineering on Saturday evening, where it failed the rear floor height check. Status suspects the failure was related to damage to the car found post-race.
Bottas now leads the standings by two points from Sims heading into the second race of the weekend, where the former championship leader will have to start from the back of the grid.
