Stefan Wilson has been ruled out of the 107th running of the Indianapolis 500 following a terrifying high-speed crash with Katherine Legge during Monday's practice session.
The two cars came together at Turn 1 after Legge failed to check up in time, colliding with the back of the No. 24 DRR Cusick CareKeepers Chevrolet car and sending both drivers into the safer barrier.
Legge managed to climb out of her Rahal Letterman Lanigan car without any visible issue, but Wilson was eventually taken away on a stretcher by the medical team.
The 33-year-old British driver will now miss the 107th running with a fractured vertebra, meaning Dreyer & Reinbold Racing will have to find a substitute for Sunday's race.
Wilson had qualified in P25 for his fifth Indy500 appearance but will now miss out on the chance to start the race as the Dreyer & Reinbold Racing team scrambles to prepare the backup car.
JR Hildebrand and Graham Rahal are the most likely candidates to replace Wilson for the Indy500 on Sunday, although we are still waiting for an official decision.
