David Ragan said there was nobody to blame but himself after wrecking his No. 6 Ford in Saturday's first Sprint Cup practice, forcing him to go to a backup car for Sunday's Tums 500.
"I just made one mistake," said Ragan, whose primary car had posted the third-best lap before the incident.
"I drove in a little bit too deep getting into Turn 1. I was just trying to drive as hard as I would in the race to try and give good feedback and just made a mistake and didn't use good judgment on what we had. We had a real good car. ...(But) there's still no reason why we won't be a contender."
Ragan had the 15th-fastest lap in the backup car in the final session.
"The biggest thing is just staying on the lead lap and, between everyone beating and banging and some cautions, we should be able to make it to the front," Ragan said. "I just have to drive a super-smart race and just have to be perfect the rest of the weekend."
