Pippa Mann and JR Hildebrand have both been released from Las Vegas' University Medical Center after overnight stays following the 15-car accident on Sunday afternoon in which Dan Wheldon lost his life.
Mann required surgery on a serious burn injury, and will require further treatment at the end of the month.
The statement from the team said:
Rahal Letterman Lanigan driver Pippa Mann had surgery last night to clean and assess a severe burn injury to the little finger of her right hand after the accident in yesterday's IZOD Indy Car World Championships in Las Vegas.
She is being released from the University Medical Center in Las Vegas this morning. She will need a subsequent surgery in 2-3 weeks to fully repair the injury but is expected to make a full recovery.
In JR Hildebrand's case, he has been released after an overnight stay for observation:
Panther Racing driver JR Hildebrand was released from University Medical Center in Las Vegas today following an injury suffered in yesterday's IndyCar Series race at Las Vegas Motor Speedway. Hildebrand suffered a severely bruised sternum in a multi-car accident and was held overnight at the hospital for observation.
Blows to the chest can have cardiac implications if not monitored properly, but Hildebrand's release from hospital on Monday morning confirms that doctors have found no such indications. However, Hildebrand will still need post-season treatment for a knee injury he sustained while filming a promotion in June.
Will Power was also evaluated at the University Medical Center on Sunday evening after complaining of lower back pain following the accident, but he was cleared and released without having to stay overnight.
However, he has since announced that he will not be competing in the V8 Supercars event on the Gold Coast next weekend as a result. Tony Kanaan has also pulled out in the wake of his close friend Dan Wheldon's death.
All the other drivers caught up in the 15-car accident at the start of lap 12 on Sunday were reviewed in the in-field care centre at Las Vegas Motor Speedway and cleared for release without the need for further treatment or evaluation.
