What happened to Ty Dillon in qualifying?

Ty Dillon, subbing for injured Tony Stewart in the #14 Bass Pro Shops Chevy at Bristol, was involved in an on track accident during qualifying. The team decided NOT to go to a back-up car. A couple of Q&A;’s with Dillon:
Q) TOUGH QUALIFYING EFFORT OUT THERE, CAN YOU TELL US WHAT HAPPENED?
Dillon: ‘Yeah, probably one of my most embarrassing moments in racing. I was coming off the corner there and getting up to speed and I clipped the apron and I slid and got loose and slid into the #38 car. It destroyed our right front and took away any good shot we had at a real qualifying lap. Not what I wanted to do in stepping into this No. 14 ride with Bass Pro Shops and Stewart-Haas. I thank them for the opportunity and I feel bad that I tore it up in qualifying and we are starting in the back of the field. But we will work on it and race back up through the field. We have been doing that the entire year. I am just disappointed in myself in making a mental mistake in getting up to speed there. Just real disappointed, but we will come back tomorrow, forget about it, and go forward.’
Q) YOUR TEAM TALKED ABOUT GOING TO A BACK-UP CAR. DID YOU FEEL ANYTHING WHEN YOU WENT BACK OUT THERE THAT MIGHT INDICATE THE NEED FOR A BACK-UP CAR?
Dillon: ‘Yeah, it just didn’t have the speed, it was real tight feeling. The aero is really messed up. These guys are the best in the business so they will get it fixed. Whether we have to go to a back-up or not, we will be alright.’(Team Chevy)
