 Chevrolet came down the front straightaway. We heard that he had a problem. Didn't know quite what it was when he got to turn one. It became very apparent. Right front tire went flat. He slid up the banking, gave a pretty good shot to the outside safer barrier at the exit of turn number one. Never spun the car, kept on going, but some substantial damage on the right front corner for Ross Chastain. I'm one of the things, a lot of rear grip.
