On the eighth lap of the already accident-riddled ABC Supply 500 race, Canadian driver Robert Wickens made contact with Ryan Hunter-Reay's vehicle coming out of Turn 2.
The Verizon IndyCar Series race was red flagged and did not restart for approximately two hours after the crash, which occurred at approximately 2:30 p.m.
Canadian driver Robert Wickens was attempting to pass Ryan Hunter-Reay, but the two collided. Wickens' auto ended up careening into the wall and then sailed over a low wall and crashed into a safety fence before spinning back on to the track.
Repairs on the wall took roughly two hours.
IndyCar officials reported that Wickens was awake and alert, but no further details of his condition were released.
"I'm just thinking about Robert (Wickens) right now", Hunter-Reay said.
Medical workers calmly attended to Wickens, who was taken to an ambulance before he was transported to the helicopter. I took my hands off the wheel when I went backwards, and I think some piece of debris came in as I was holding them (my hands) in, kind of just smacked the top of them so I took of bit of beating, but nothing is broken, just some swelling and some cuts.
James Hinchcliff was caught up in the wreck and held his wrists as he slowly left the vehicle. We will see everyone this weekend from Gateway Motorsports Park outside of St. Louis, Missouri for the Bommarito Automotive Group 500 on August 24-25.
"It's an exceptional day, but right now, Rob and James and everyone involved in that, Ryan, have our thoughts, and it's tough to really celebrate after what happened". "It's unfortunate but I just hope Robert is okay".
Hinchcliffe is a team teammate of Wickens on the all-Canadian team. "He's hurt. He's awake and alert and at least he's alive", French driver Sebastien Bourdais said.
Fittipaldi was checked for an ankle injury.
Rossi's plain sailing lasted until Lap 90, when his lead of more than a dozen seconds over Power dissipated to under four as he struggled to put a lap on AJ Foyt Racing's Matheus Leist.
On the race's start, Graham Rahal tangled up with Spencer Pigot as cars tried to get off to a quick start in the 200-lap race. Pigot's vehicle did not return to the race but the first eight laps were run under the yellow flag.
Wickens' accident was eerily similar to the crash that claimed the life of British driver Dan Wheldon in 2011. Numerous drivers admitted they thought about what had happened to Wickens and made a decision to take a more cautious approach to the remainder of the contest.
Rossi's deficit to point leader Dixon has been cut by 41 in the past two races; he's just 29 back.
"I talked to Hinch and Sato, there was so much debris and fluid on the track".
"That's the worst thing you can see".
