Wilson’s Dreyer and Reinbold Racing-run car was hit from behind by Katherine Legge’s Rahal Letterman Lanigan Racing machine after cars ahead of them stacked up at Turn 1.
Both cars spun and subsequently hit the wall at differing angles at high speed. While Legge’s struck the wall side-on, and she was unhurt, Wilson’s hit the SAFER barrier head-on.
As the AMR safety crew attended to him, they immediately called for a back brace and stretcher before he was extricated from the car in a carefully-executed procedure that took over 10 minutes. He gave a thumbs up as he was loaded into the ambulance.
The 33-year-old from Sheffield, UK was taken to the medical centre and then transported on to a local hospital for advanced imaging, where the injury was diagnosed.
