The network says a full investigation is under way and use of the camera is suspended indefinitely. Earlier, NASCAR said it would wait for Fox Sports to conclude its review before deciding if such technology would be used in the future.
Charlotte Motor Speedway said 10 people were injured when part of the drive rope landed in the grandstand; three were taken to hospitals. All were checked out and released soon after.
In a statement, Fox said it was “relieved and thankful to know that the injuries to fans caused then CAMCAT malfunctioned at Charlotte Motor Speedway were minor.”
The network again apologized for the disruption.
Several drivers, including then-leader Kyle Busch, reported damage to their cars from the rope.
