Debris and a whole tire spewed into the stand where fans were watching, injuring at least 33 people in the accident.
Huffington Post reports:
Speedway President Joie Chitwood III has a news conference scheduled for Sunday morning to give the latest update on repairs and any safety changes that could be made before the “Great American Race.”
The 12-car crash began about 200 feet from the start-finish line as the front-runners approached the checkered flag. Leader Regan Smith attempted to block Brad Keselowski for the win, triggering a horrific pileup that could have been much worse.
Track workers were scrambling late into the night to repair a huge section of fence that separates fans from the high-speed track.
