IndyCar said in a statement the 29-year-old Canadian was scheduled for surgery Monday night in an Allentown hospital.
While Hunter-Reay spun, Wickens' auto went airborne and into the catchfence before bouncing off and spinning several times in mid-air before coming to a rest along the inside retaining wall on the track. Wickens' vehicle then ran on top of Hunter-Reay's and smashed against the wall and catch fence at full speed, completely disintegrating on impact. "There's something that has to be thought out with either increasing the size of the wall, putting something like a bullet-proof material in front of these existing fences in the corner to be able to keep the cars inside the track".
Medical workers attended to Wickens, who was awake and alert, before transporting him to Lehigh Valley Hospital-Cedar Crest via helicopter.
Like him, drivers were shaken by the crash, which delayed the race for two hours while the catch fence was repaired and cast a pall over the scene. Four years later, the closed cockpit debate was re-ignited when Justin Wilson died after being struck in the head by debris from a crash at Pocono. Teammate and fellow Canadian James Hinchcliffe was also involved in the crash. Hinchcliffe was cleared and released from the medical centre. "He's as tough as they come, I know he'll be focused on getting back on track".More news: Clarkson Tallies 28 against China in International Debut
"We'll enjoy this one, but dark cloud (today)", Rossi said.
"Obviously, I'm just hoping Robbie's alright". But he got back in the auto.
Driver Sebastien Bourdais echoed Hinchcliffe's sentiments.
Wickens remains in the same Lehigh Valley Hospital - Cedar Crest hospital in Pennsylvania. where he was transported after being involved in a crash during Sunday's ABC Supply 500. After a almost two-hour delay, the race resumed without another spate of aggressive driving - Graham Rahal tangled with Spencer Pigot as the field was brought to green - and ended without another caution.More news: Here's Why a Harvard Professor Says Coconut Oil Is "Pure Poison"
Pocono Raceway president Ben May said about 80 feet of fence and a few posts were damaged in the wreck. Bourdais raised concerns about the quality of the repairs and condition of the fence before he got back in the vehicle. Track President Ben May said: "It may not be the prettiest job but it's going to be safe".
Bourdais said the repairs were "pretty lousy".
Hinchcliffe and Wickens form the all-Canadian Schmidt Peterson Motorsports team. The two raced each other as youngsters in Toronto and Hinchcliffe, runner-up on ABC's "Dancing With The Stars" in 2017, helped lure Wickens to IndyCar this season after a successful career in Europe.
