DAYTONA BEACH, Fla. (AP) - Some NASCAR fans have been injured by flying debris from a final-lap accident during today's Nationwide Series race at Daytona International Speedway.

Large chunks of debris, including a tire, sailed into the grandstands when a car flew into the fence.

The crash began as the field closed in on the finish line and sent rookie Kyle Larson's car sailing into the fence that separates the track from the seats.

The car had its entire front sheared off, with the burning engine wedged through a gaping hole in the fence.

The accident spread into the upper deck and emergency crews treated fans on both levels. There were five stretchers that appeared to be carrying fans out, and a helicopter flew overhead.

Neither NASCAR nor track officials had any immediate details on injuries.

Tony Stewart won the race, but skipped the traditional post-race celebration.
