(AP) - NASCAR will look at the placement of gates at its tracks after a Nationwide Series car crashed through the fence at the Daytona 500 and injured more than two dozen fans. Steve O'Donnell, NASCAR's Senior Vice President of Racing Operations, said on Saturday that the gate where rookie Kyle Larson's car hit the fence was locked, but that pieces of the car still went through the fence. He said the safety elements of Larson's car appeared to work, but the section that the engine is tethered to sheared off and sent pieces of the car flying into the stands. O'Donnell also said two of the injured fans are still at the hospital, but that everyone else has been released.
