I know I was there & the wreck that happened Saturday night had Tommy Rhodes Jr go over Hupps Right rear in a similar fashion. Hupp did barrel rolls where as Tommy did endo's. Here's a pic of the car in the pits after the races. You can find updates on Tommy on Waynesfield's Facebook page.
BTW the front axle came completely off the car & over the turn 3 fence & it was on about the same place as Hupp's.
