Brad Keselowski was taken to the hospital after he crashed during a test session at Road Atlanta, Penske Racing said.

The severity of the crash was unknown but team officials said that Keselowski was able to exit the car under his own power. He was taken to the hospital as a precautionary measure.

Keselowski was in Road Atlanta testing for the upcoming Sprint Cup race at Watkins Glen International. He tweeted that he was doing about 100 miles per hour when the brakes failed and the car hit the wall head-on. That part of the wall did not have a SAFER barrier.

Keselowski tweeted that he should be able to race at Pocono Raceway this weekend, indicating that there were no serious injuries, just cuts and swelling.

Update: Penske Racing issued a statement about Brad Keselowski’s condition. It read:

Due to Brad Keselowski’s accident while testing at Road Atlanta yesterday, he will not participate in the NASCAR Nationwide Series race this weekend at Iowa Speedway. Parker Kligerman will practice the #22 Discount Tire Dodge Challenger on Friday, while Sam Hornish Jr. will qualify and race the car on Saturday. Penske Racing will continue to evaluate Brad’s condition. Further information will be provided as it becomes known.

Update 2: Brad Keselowski has been cleared to race at Pocono this weekend. Dr. Jerry Petty said of Keselowski:

After meeting with Brad Keselowski today it became clear that, despite an avulsion fracture of the left ankle, he would be able to compete this weekend at Pocono Raceway without any limitations.
