KANSAS CITY, Kan. -- Kyle Busch's car was a mangled mess early in the LifeLock 400, thanks to the man who will replace him at Hendrick Motorsports next season.
Busch slammed the backstretch wall head on in the No. 5 Chevy after being bumped from behind by Dale Earnhardt Jr. on Lap 29.
"I got run in the back of and spun out down the back straightaway for absolutely no reason," Busch said. "It was a pretty stupid move on [Earnhardt's] part.
"I'm sure these guys he's going to be working with next year don't really appreciate it because they have a championship they can win this year. I don't know what he was thinking or what the problem was."
And Busch said he had a contending car at Kansas.
"It's very unfortunate," Busch said. "That car was top three, definitely, maybe even a winning car. I was just minding my own business and got run over."
Earnhardt took the blame for the accident.
"It was my fault," Earnhardt said. "I thought for a second he was going to give me the bottom down the straightaway. Then he just moved up and I go into him. I should have been able to get out of [the gas]. I was screaming for him to save it, but he couldn't gather it up."
