Kaz Grala took a hard frontal impact into the Turn 4 wall as practice was winding down. Grala’s Rick Ware Racing Ford Mustang Dark Horse appeared to get loose, shooting him hard to the outside wall and then back down the racetrack. Grala climbed out under his own power.
“That was so quick, I didn’t feel. Like I had any time to react to it,” Grala said. “It was definitely unexpected. We had been a little free through practice, but our race pace was actually really good, I felt like. I felt like that was maybe our best car of the year, and it was gone out from under me before I could try to save it.
“I’m definitely really disappointed; really unfortunate for our team. We’re obviously not in a good position for backup cars, so we’ll have to see what we have to work with for tomorrow, but far from an ideal situation. But I’m just glad I’m all right, and we’ll do what we can for tomorrow.”
Zane Smith also crashed during practice. The Spire Motorsports driver wasn’t sure if it was a tire issue that caused his Chevrolet to hit the wall and damage the right rear.
