Two other IndyCar drivers involved in the 15-car wreck that killed British driver Dan Wheldon at Las Vegas Motor Speedway on Sunday were treated for minor injuries, their teams said.
Will Power of Penske Racing, who finished second in the title standings behind champion Dario Franchitti, complained of pain in his upper back after his car went airborne in the crash.
But "there was no evidence of significant injuries so he has been released" from University Medical Center in Las Vegas, Penske Racing said.
Another driver, Pippa Mann of the Rahal Letterman Lanigan team, had surgery Sunday night at the same hospital to treat a severely burned pinkie finger on her right hand. She was being released Monday morning, her team said.
[Updated, 12:20 p.m. Oct. 17: A third driver, J.R. Hildebrand, suffered a “severely bruised sternum” in the accident and was held overnight at University Medical Center but was released Monday, his team, Panther Racing, said.]
The Izod IndyCar Series, meanwhile, announced that it canceled its championship banquet scheduled for Monday night at the Mandalay Bay Resort in Las Vegas.
The series also said information on a public memorial for Wheldon will be released at a later date.
