The Daytona 500 ran as scheduled Sundaydespite a jaw-dropping crash a day earlier that flung debris into the stands at the Daytona International Speedway.

At least 28 fans were injured when more than a dozen cars piled up in the final curve of the Nationwide Series Drive4COPD 300 in Daytona Beach, Florida, on Saturday. Some of the debris went over a 22-foot-high fence that was built in 2010, and some of it went through holes as the fence shredded when a car slammed into it and bounced back onto the track.

"At 8 a.m., we met with NASCAR, we reviewed all of the repairs that we made last evening," speedway president Joie Chitwood told reporters Sunday morning. "We worked late into the evening and are prepared to go racing today."

Some of the fans who were sitting in that area returned for Sunday's race, which began just after 1 p.m. ET, Chitwood said. Jimmie Johnson won the race, edging out Dale Earnhardt Jr. and a host of others down the stretch.
