CONCORD, N.C. (AP) — NASCAR will wait on Fox Sports' investigation of what caused an overhead TV camera rope to snap during the Coca-Cola 600 before deciding if such technology will be used in future races.
NASCAR spokesman Kerry Tharp told The Associated Press on Monday that there were no plans to use the system at upcoming races "so we'll have ample time to review."
Fox indefinitely suspended use of the system after the nylon rope fell onto the track about a quarter of the way through Sunday's 600-mile race. Charlotte Motor Speedway said 10 people were injured when part of the 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.
Fox was expected to release more information about the breakdown later Monday. The network said the system was used successfully at the Daytona 500 and last week's Sprint All-Star race in Charlotte.
Fox's final NASCAR telecast this year comes Sunday at Dover International Speedway.
Tharp said NASCAR would let the network determine what went wrong.
"We'll sync up with them on what they have learned this week and go from there," he said.
The network explained how the drive rope moves the camera back and forth and failed near its turn one connection. The camera, it said in a statement, did not come down "because the guide ropes acted as designed."
The pictures such cameras provide can be extraordinary. But in this case, the failure brought confusion and chaos to the racers and the fans.
Coca-Cola 600 winner Kevin Harvick thought he was imagining things when he noticed the black rope on the track. He was among the lucky ones who escaped without damage. Busch said he heard a "thunk" when he ran over it and knew he'd have problems.
Busch used a cellphone to take a picture of the mangled metal around his front, right-side wheel so his team could figure out how to repair the damage.
Marcos Ambrose dragged a piece of the rope that got caught up in his car behind him on the track. Mark Martin also reported problems after driving over the rope.
NASCAR red-flagged the race for about 30 minutes and allowed teams back to their pits to get their cars back to race trim.
NASCAR first threw a caution flag before two red flags came out. It eventually allowed the cars to come into the pits, giving crews 15 minutes to work on their cars.
During the break, Busch's crew frantically worked to repair several problems to the right front wheel well. After completing repairs, the crew slapped high-fives as the car rolled back on the track.
Busch remained competitive and was running in the top five at the midpoint of the race. But his night ended in frustration when his engine blew up on lap 253. He said the engine problem was not related the rope damage. He thanked NASCAR for how it handled the unique stoppage.
"I commend NASCAR for taking the initiative and letting us repair our damaged cars from the issue we had," Busch said.
Busch said he never saw the nylon rope.
Ambrose wound up ninth behind Harvick, the second top-10 finish of the year for the Richard Petty Motorsports team.
Kasey Kahne led 156 laps, most of the night, and was second to Harvick. He was as bewildered as everyone else with the TV cable across the track.
"I've never seen anything like it," he said. "I came around turn four, saw it wrapped around Kyle's car, hit mine. I thought I was seeing things."
The camera hung in place over the large painted logo on the grass between the start-finish line and pit road.
Fox broadcaster Chris Myers apologized during the telecast several times to fans, drivers and race teams for the disruption. The network's statement offered "a sincere 'thank you' to the staff at CMS for attending to the injuries and keep us informed on this developing situation."
Busch wasn't sure anybody had seen that happen before and offered a solution: "Maybe now we can rid of that thing."
