A medical bulletin from the Verizon IndyCar Series released at 5.45pm BST on Monday confirms that Justin Wilson remains in intensive care following his freak accident during Sunday's ABC Supply 500 at Pocono Raceway.
The bulletin contains no new information and simply restates the broad facts released late Sunday evening after Wilson was airlifted to a nearby hospital.
The latest bulletin reads in full:
"Verizon IndyCar Series driver Justin Wilson remains hospitalised in a coma in the intensive care unit at Lehigh Valley Health Network Cedar Crest Hospital in Allentown, Pa., after sustaining a severe head injury during Sunday's event at Pocono Raceway. He remains in critical condition.
"IndyCar continues to send its thoughts and prayers to the family and thanks the entire motorsports community for the outpouring of support.
"Additional updates to Wilson's condition will be released when available."
Wilson was struck in the head by a large piece of flying debris - apparently part of the nose cone - following a separate crash involving Ganassi driver Sage Karam on lap 179 of the 200-lap race at the tri-oval in Long Pond.
Wilson was immediately attended to by multiple safety crews and extracted from his car, then moved by ambulance to the in-field care centre from where he was airlifted to hospital by medical helicopter.
Karam was also taken to hospital by ground transport for evaluation after the incident.
Wilson's wife Julia and brother Stefan - himself a former Indy Lights competitor - were not present at Pocono for the race but immediately flew to be with him, thanks to former IndyCar champion Tony Stewart loaning his private plane to get them to Pennsylvania as quickly as possible.
"I thought Justin was okay the whole time. I thought he was in an ambulance and was going to get a check," said Wilson's team mate Ryan Hunter-Reay, who was declared the eventual winner of Sunday's race under caution.
"All I know is that he was unconscious, he was not responding and he was airlifted," Hunter-Reay added.
"That's all very bad. I'm very worried right now," he admitted. "With heads exposed and when you get flying debris, it's a bad luck deal. Our thoughts are with him. I know him and his family well, they're great friends of ours. Really, really just thinking about Justin right now."
Drivers from across the world of motorsports have taken to social media in the hours since the accident to support Wilson, using the hashtag #PrayersForJustin.
Wilson has competed in US open wheel racing since 2004, after a season in Formula One racing for Minardi and Jaguar. Wilson took four wins in 54 starts in the Champ Car World Series, and to date has three wins in 104 starts in the IndyCar Series.
