Busch wasn't injured in the accident.
"We just got hit from behind, and along for the ride we went," he said, adding "Yes, lovely," when asked if he was OK.
NASCAR sent the race into overtime after the final accident for one attempt at a green-white-checkered finish, and it seemed as though it might have been Kenseth's race to win.
He led a race-high 142 laps and was the leader on the final restart but was passed by Edwards on the first lap of overtime. He tried to get the lead back and was battling Edwards with no drafting partner. He never saw the pack coming behind him and, with nowhere to go, fell out of contention in the blink of an eye.
"Carl just got a rocket restart there, and he cleared me down the backstretch," Kenseth said. "He just got a huge run somehow. I was still second. I thought we still had a shot. I tried to get around Carl but he blocked, which you should. We got real wide getting up there and got pretty far to the top, and I just didn't watch the runs from the guys way in the back.
"I saw David at the last minute but he was going too fast. If I pulled in front of him I was just going to get wrecked. I just had to bite the bullet and try to find the hole, which there wasn't one. It was a disappointing end to the day but man, we had a great car.'
That's when Ragan and Gilliland came charging out of nowhere, sweeping past Edwards and Johnson and to the front.
"That was crazy," Edwards said. "I blocked everybody I could. I was doing everything I could. I blocked Matt and I thought, 'Oh, we've got it.' And then I saw Jimmie coming and I blocked him and I thought, 'Who is that back there?' It was this Ford freight train coming and I just couldn't stay in front of them."
