DAYTONA, Fla. -- A local NASCAR fan witnesses the Daytona Nationwide Series crash right in front of the fence pierced by the debris from the wreck.

"I looked over and saw a hole in the fence, and looked behind me and saw a tire, a man under a tire and there were people screaming where's my kid and the emotion was running high there," said Tyler Andersen of Jacksonville.

16-year-old Andersen recorded the crash on his iPhone while sitting in row 8watching the last lap of the Daytona Nationwide Series COPD300 race. Herecorded the multi-car crashthat sentflying debris through the safety fence and into the grandstands right below from where he was sitting.

"The smoke and the debris in front of me, it was nothing like I've ever seen before," said Andersen.

In his video you can see the smoke over the fence and people crowding around the injured, calling for help. At least 14 were treated on-site. A spokesperson for the Halifax Medical Center in Daytona says initially 12 people were transported to there, but onlyseven had injuries related to the crash. Of those seven, two were in critical condition upon arrival, but they are no longer listed as being critical.

Newsgirls races have been Andersen's passion for over five years, but today's race will be one he'll never forget.

"I've watched NASCAR a lot of times and this is just not supposed to happen," said Andersen.

At least 12 cars were involved the crash. One driver was hospitalized and is being kept overnight for observation. Number 32, Kyle Larson's car is the one that lost its engine and tire in the wreck. Larson escaped the crash unharmed.

"As with any of these incidents we'll conduct a thorough review as we do with all our events, learn what we can and see what we can apply in the future," said Steve O'Donnell Senior VP of racing operations NASCAR.

As for Andersen, he says he is praying for the families involved and says this won't stop him from going to future races.

"I want to thank God for looking over me and I hope he's with the families right now, for all those involved," said Andersen.

NASCAR began repairs of the facility on Saturday and say they will be ready for Sunday's Daytona 500.
