Following a messy, stacked-up start the Juncos Hollinger Racing driver was hit up the rear by Chip Ganassi Racing’s Scott Dixon – who had already brushed wheels with a fast-starting Colton Herta (Andretti Global) as the race went green moments earlier – on the run towards Turn 1.
The nose-to-tail contact with Dixon sent Grosjean spinning out of control through the dust towards the apex of the first corner.
