CONCORD, N.C. (AP) -- Fox Sports says on Monday it still had not determined why an overhead TV camera cable snapped during the Coca-Cola 600.
The network says a full investigation is underway 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 future races.
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.
Several drivers, including then-leader Kyle Busch, reported damage to their cars from the rope.
The network said the system was provided by Austrian company CAMCAT. The rope that failed was certified for a breaking strength of 9,300 pounds.
