Wilson was unconscious when he was transported by helicopter to a hospital near the Long Pond, Pa., track. In a statement late Sunday, IndyCar officials said Wilson was in a coma.

The piece of debris came from the car of Sage Karam, who spun into the wall with 18 laps remaining in the race. Impact from the crash sent pieces of the car flying into the air as approaching drivers passed by. One of the larger objects can be seen falling onto Wilson’s head before his car veers to the left directly into an interior wall.

“INDYCAR sends its thoughts and prayers to Justin, his family and Andretti Autosport during this difficult time.

“Additional updates to Wilson’s condition will be released when available.”

Safety personnel quickly surrounded the British driver, who was airlifted from the track.

Wilson, 36, is from Sheffield, England, and resides in Longmont, Colo.

He has competed in American open-wheel racing since 2004, and this season joined Andretti Autosport for the final six races.

“It’s a tough one right now,” team owner Michael Andretti said after the race, unable to provide an update on Wilson’s condition. “Our thoughts and prayers are with Justin right now.” 

Ryan-Hunter Reay, an Andretti teammate of Wilson’s, was the eventual race winner. 

Hunter-Reay said he was told Wilson was “unconscious and not responding” when he was airlifted to the hospital.

“I saw the trucks around him. … First thoughts with Justin, for sure. He’s my friend. I have no details right now, so it’s a bit hard not knowing anything,” Hunter-Reay said, via USA Today. “I thought Justin was OK the whole time. I thought he was in an ambulance and was going to get a check.”

Wilson’s brother, Stefan, tweeted Sunday night that he was attempting to get to the hospital from Indianapolis. Justin’s wife, Julia, was also traveling to Pennsylvania from their Colorado home.
