Channel 9 has learned the Daytona International Speedway and NASCAR will launch a major review of the catch fences along the track following a dangerous crash that injured 33 people Saturday during a Nationwide Series race.

Sources told Channel 9's Blaine Tolison risk management officials and attorneys with the speedway looked at the catch fences and it will be up to both the speedway and NASCAR to make changes.

New videos posted on YouTube by race fans show new angles of the unforgettable crash in which Kyle Larson's race car went airborne, slamming into the fence, sending his engine, a tire and other debris right through it.

"It happened right down in front of us and I was just shocked to see that the poles and everything were gone," said race fan Lenny Tobie. "I heard, like, a loud explosion."

In all, more than 28 fans were injured. It's now up to Speedway officials and NASCAR to determine how well the fencing did its job.

"Whatever comes out of it, we will definitely react, and that's the key," said Speedway President Joie Chitwood. "And we've done it before and if we learn some things out of this, we'll do it again."

For now, the speedway and NASCAR won't publicly discuss anything they may have already learned, but Chitwood praised his personnel for how they handled the accident.

"The grandstands are huge. We've done, I think, a good job making sure that drivers, fans and everyone is safe as possible," he said. "There are things that happen that are unexpected."

Next month, there will be motorcycle racing at the track. There won't be cars on the track until just before the Coke Zero 400 in July.

If NASCAR implements changes in Daytona, it could affect other tracks across the U.S. where the association sanctions racing.

Seven race fans remain in the hospital Monday.
