He thought it might have been a tap from Roush Racing teammate Greg Biffle, who was following Kenseth from the airport to Indianapolis Motor Speedway for testing.
"He always runs into me, so I thought it was him joking," Kenseth was quoted as saying Monday in a NASCAR news release. "It wasn't. It was a student driver and instructor; just pile drove into the back of me. That was exciting."
As for Sunday's bump from Gordon, which dropped Kenseth from first place to a 22nd-place finish, Kenseth said he is moving on.
"I'd rather just keep to myself and go and do my job and not have any of that," Kenseth was quoted as saying. "But if you're going to be competitive and you're going to try as hard as you can every week, try to run up front, do all that, it's pretty hard not to ever get in a conflict with anybody. It's just part of the business."
